    I like the idea of using an array of many SMD LED to achieve high lumen in lanterns rather than one or a few high power LED.
    You should post photos of your lantern and provide the link to your eBay store.
    Or if your link is deleted by our overenthusiastic mod then PM me.

    I live in Greece, so i made a listing to the UK ebay. In case you want to find it, just search at ebay.co.uk as "LED lantern"
    I guess i can to US but have not experience with that.


    In case you have any other question. feel free to ask.

    Cheers all, and keep darkness at bay

    Just to post a couple of vids.

    This is my new made lantern ΙΓ - the third of I series. 13inch tall, large globe and more warmwhite light, being a bit more powerful than the others.

    Love it! Great mix of old and new.

    Question, do you find it dim enough at 10%. That still strikes me as relatively bright.

    Hello semiman,

    that excactly i had in mind. having a vintage looking item, yet outputing what contemporary electronics can offer.
    hmm.. , the dim is not dim enough huh? Hmm yea.. it can be said so since, in the dimmest setting is about twice more bright that a fully running petroleum hurricane lamp.
    By the way, this was made by hunch and personal preferences rather than asking. Feel free to give ideas

    Nevertheless, i am planning a new model lantern, having fewer smd leds that can reach as much as 130 - 140 lumens per watt! A lantern running at 500 lumens at max setting is what i desire for now, having around 70-7 hours of service per charge (for the small 10'' lanterns and more for the larger ones). This is still in the wish list of course


    ps: Thank you starthalo

    I would love this for camping and often the light is just for the mood or to make it back to the trailer and in the trailer often with others asleep. In those instances a quite low setting would be nice. I have a small lantern that is about 200 lumens but runs mainly in the 10-20 range as its enough for what is needed at the time.

    Ok, i will have that in mind. BTW, i make those lanterns with max light output in mind, knowing that, 80% of the time, the lantern is required to be on a lower setting, but when settling around or working or just doing about anything for that 10% of the on time, you really want a bright light.

    I was thinking my next lantern series, to have a button that would allow a "boost" mode , e.g. whereas in nominal light output range 50-500 lumens in "boost mode" to be achieved as much as 1500 lumens!

    What u think guys?

    Can't find your listing for this lantern on eBay uk. Can you send me a link? Interested in buying... Are you using genuine Dietz lanterns as a base? Also check out Kirkman lanterns as an upgrade over Dietz.

    I am gona have a site that will present there my lanterns soon.

    regarding the chassis, nope, i am using chinese lantern chassis that meets my criteria as durable enough, tank diameter and depth to accomodate the electronics and battery holder etc. I really want to modify a Dietz lantern, but material costs will be considerable elevated.

    In any case, those common brand chassis lamps have being reworked with epoxy putty giving a solid feeling, stregth and will endure hard knocks. In general lamp is safe as long as the glass is intact. If knocks in the lamp's body are hard enough to break the glass, then lamp chassis and internal electronics are in danger too.

    Being said all that, anyone that will treat my lanterns with a minimum of respect should expect them to endure a lifetime. (Except batteries of course that in 3 to 5 years will need replacement)

    Great job Baroutologe, now how about some mild weatherproofing for light outdoors duty (in case of rain or high humidity). Do you think you will be able to make the lowest output even lower for the IΓ by the way? Also, is there parasitic drain when the light is turned off?

    Μπράβο μεγάλε.

    Cool! Checked your site out. Nice job! Loving this project!

    What are the specs of your LEDs? Are they heat sunk? What are they mounted on? What current are they driven at? I'm thinking they are running at very low current to keep them cool, and using many to achieve high lumen output. What is the runtime/current draw at max w 4 cells? It will run on one cell, so more cells only increase runtime, correct? Draw with one cell? The cells charge internally with your included charger? Where is the on/off switch? Does the fuel cap and wick control play a part?

    How would you feel about building one if I drop shipped a Dietz or Kirkman to you? They are available with a frosted globe, so I would be paying for the lantern and frosting up front.

    Hello phaseburn,

    Those Leds are of superbright quality, typically 80 lumens / watt, clustered together 96 used, operated at 1 or 2 - 20mA current, and due to being so many they work air cooled.

    Concerning the specs of the I series: IB and IΓ lamps draw some 1,6 amps at 3,7 volts (nominal) either being 1 or 4 cells current draw does not change. All cells are placed inside in an electricall parallel mode wheras holder requires them in a series look. Lamp will operate with just one cell , placed anywhere in the holder, lasting 1 2/5 hour or so at maximum setting. (good cell)
    The more the merrier when it comes to cells :P with a respective increase in run time.

    Yes, cells charge internally. Once inserted to the lantern, there is no reason to take them out again unless they have expired after years of service.
    If you study the videos, the wick control is used for altering lanterns's brightness and serves as an on / off switch. Fuel cap is just for decor here.

    Finnally, yes i have already undertaken a promise to make a custom lantern per wish specs. I can do that for you.

    Cheers

    I'm working on a similar personal project and I'm stuck at the driver.

    I'm looking for something with single li-ion input, in the neighborhood of 1.5A output and external current regulation as in a pot or some sort of a turn knob. Any ideas?

    Default Re: Baroutologos's Handcrafted - Rechargeable LED Hurricane Lanterns

    hello Evo,

    Yes, the driver circuit can be a pain.. Mine so far consisted of a pulse width modulated 555 timer operating a transistor switching a custom transformer that meets string LEDs needs. Now i am going to experiment with dedicated LED driver low voltage ICs and Boost-Buck low voltage ICs for simplification of design.

    Nevertheless, a circuit as simple as that in order to run your LED strings effectively requires basic knowledge and experience of electronics, soldering, some inspiration and the secesary tools. Of course having all those, trial and error cannot be avoided for novel projects, a procedure that takes me considerable time.

    ..
    Li ions cell(s), have additional issues to tackle with, in contrast of an alcaline operated circuit, i.e. you need a protection circuit (under voltage, overvoltage, overcurrent) that exist readily, a charger and perhaps some fusing for additional safety.

    My piece of advice is design your project in electronic terms, search the component values to meet your criteria, (usually the IC that regulates current works with a pot 10k or 100K are typical values) procure a breadboard, and start experimenting.

    Default Ledaddict's custom made Lanterns

    Since i had presented my work here, i was contacted by member Ledaddict (Bryan), to discuss the potential of making him a custom lantern(s). An e-mail conversation was made
    in order to identify what it would to be created.


    Prerequisites were,
    * a superior quality vintage hurricane style lantern
    * made to provide considerable luminosity (1000 lumens+) with full dimming capability
    * robust in making destined to hold in time
    * powered by 12volt (main PSU adaptor or battery used during power outage, camping etc)


    Bryan, one of the most patient individuals i have known, was being informed of the progress, we were discussing technical issues, ideas,how-to(s) etc.
    I must confess, i have been inexcusable delayed (2 months +) at making those lanterns since i have experimented (time allowed) with almost everything from circuits
    and IC boost regulators chips to brittle 2523 samsung smd leds etc + the fact that most electronics components come from China and take an age to arrive. After the time consuming experimentation came to a halt, finnaly lanterns were assembled and tested.


    Specs:


    Kirkman No2 Champion Hurricane style chassis


    Working voltage 12v (max 1.7 amp draw around 90% efficiency)
    Power output 0.5 / 0.8 - 12 / 20 watts (potentiometer regulated)
    output: (flyback) 80-300 volts DC. At 330v circuit halts.


    takes an ordinary corn led bulb that is modified to run in dc rather AC, with max dimensions 5 cm circumference and 13cm long. Standard E27 socket.
    Current Led Bulb 48 x 5630 smd leds,approx power input 13watts out 1000 lumens average
    wick controller provides the dimming and on/off function and has an auxiliary master switch for rapid start.

    I have not dispatch them to him yet, since i await some new bulbs to arrive since the already existing are pure white and neutral white. Those need to be warm white both.

    Everything stated above is correct.

    My only regret is that I could not visit with the engineer in person to speak with him
    and share some good food.

    This man knows what he is doing and he takes the time to explain it to those of us who are not electrical experts.

    γεια σου nik,

    Tell me stupid but now i noticed your comment. sorry.
    Concerning the mild weatherproof for outdoor light, i am working on it. Generally, high lumens output are (so far) incompatible with water resistance but solution is around the corner.. The lowest posible output is done lower... in few days or a week i will present the next K-series.
    Parasitic drain in the I-series is null. In the K-series that is to come is about 60-70uA.

    Ευχαριστώ φίλε

    Default Re: Baroutologos's Handcrafted - Rechargeable LED Hurricane Lanterns

    Hello all,


    Today i am going to present my third lantern of the K series. Generally K-series, is the result of further improving my lantern making technique and addressing a bunch of issues as

    * increased luminosity with more efficiency
    * dimming down to few lumens
    * replaceable led bulbs
    * using high efficiency LEDs of still warmer white color
    * simpler electronic design

    Overally, the vintage outlook of the lantern is pretty much the same as the previous series i.e. modified petroleum hurricane lanterns, but the above attributes were achieved after hard work and lots and lots time of experimentation in order to put all together despite the inherent restrictions of making such lanterns.

    About the KΓ lantern
    ........

    Chassis: Standard 30cm height (12''), plain type, reinforced with standard glass treated so as to be semi-frosted (antiglare) and labeled

    the "bulb": An improvised LED fasten-heatsink 5-sided element that has mounted x 15 (5 each side) 2323SMD Samsung SPMWHT221MD5WAW0 see datasheet here http://www.led1.de/shop/files/Samsun...1MD5WAW0S0.pdf
    Ahhh... those tiny and rather expensive SMD leds are a pain to be handled and soldered without damaging them. But the light they emit is almost heavenly. Warm white (2700K)
    That improvised bulb is mounted on a GU10 male socket that fits on a porcelain female socket permanently fastened on the lantern chassis. If ever for some reason the bulb is damaged, easily can be replaced, let aside
    the fact that LED technology improves month after month so the 125 lumens / watt of this bulb could be easily 200 or even 250 in few years. :P

    the batts: ΚΓ lantern once open the bottom lid, takes in a similar fashion with all lanterns made by me so far, takes 3 x C alkaline batteries of 1.5 volts each. They are calculated to last according energizer's datasheet around 12 hours
    at max.

    the circuit: A use of MC34063A boost controller IC, that inputs from 4.5 volts down to 2.5 volts whereas providing stable power output around 1.35 watts. Its efficiency is around 85% at max setting and in lowest voltage.
    (meaning in most current draw for those who know about electronics). In other words, lamp's brightness is undiminished irrelevantly of batteries' status (unless exhausted). At that power lamp shines with 140+ lumens at
    max.
    Minimum luminosity is less than a lumen. Once closed (FET switched) no quiescent current. The circuit needs some 25mW to run. Once the bulb is removed circuit will stay idle (no burn). A pot is attached to circuit for
    voltage level adjustment (power out restricted)

    weight: Less than 900gr with batteries (2 pounds)

    ...

    Forgive my tech enthusiasm but i am an enthusiast :P

    i made this lantern having in mind those who want a vintage, unique made lamp, robust, that needs no maintenance (higher power rechargeable li-cells needs), that will stay year after year in place and when it is needed it would be there to provide all the light you need and create an wonderful atmosphere. Also being independent of charger will continue happily to light once supplied with a fresh set of batteries.

    Hello all,

    During my holidays back in home, i searched the cellar and surprising i found my very first lantern i had when i was little child. Its a BAT brand, No 158 made in GDR or Germany Democratic Repuplic or Eastern Germany. This must be more than thirty years old (its 25 years in my possession and was given to me).

    It was partially rusted, its tinning damaged and in general nonfunctional. After treating it with acid to remove rust and paint with a anti-rust and then black, i proceed with the standard methodology of converting it to a electrical lantern. It follows the general lines of K series, as replaceable bulb capability, voltage boost controller with short circuit protection (makes use of the FP5138 IC), adjusted max output power 250-400 lumens (set to 350).

    Its named KA. Has no protection circuit embeded and must take protected 18650 cells. A genuine antique lantern converted to powerful led one.

    ps: a little promo i good i suppose

    Hi @ all,

    Free time allowed, i completed 4 more Hurricane lanterns of the K series modes namely KA,KB,KΔ & ΚΕ.

    KA - is the above presented lantern only having its exterior artistic details worked out http://rechargeable-led-lantern.com/?p=225

    KB - is a retrofitted MEVA contemporary lantern http://rechargeable-led-lantern.com/?p=287

    KE - is a vintage (around 20 years old) retrofitted MEVA lantern in a bloody red shinny color http://rechargeable-led-lantern.com/?p=290

    KΔ - on the other hand is a retrofitted chinese contemporary lantern big enough to take 4 Li cells http://rechargeable-led-lantern.com/?p=299


    In any respect i have perfected the circuits (far less bugs), the aesthetics and functionality..
    Any ideas for further improvement is welcomed.

    Congratulations on a great thread and a very nice product apparently. Certainly a novel idea.

    But PLEASE lose the trustfire cells and use some decent Panasonics or Sanyos instead, especially when posting on CPF!

    I beg your forgiveness about my insult to any knowledgeable CPFer, but if i may say, those near to recycle cells are only intended for test running, test charging and just staffing the newly made lanterns just to confirm they operate as intended!

    Thanks a lot for your kind words.

    A lantern with a driver that can handle a wide range of input volts would be nice. Something that could run on internal 18650's or AA good in emergency to have optional power source, also maybe a plug in external power source such as 12v car battery, power supply or R/C hobby lipo pack's. Possibly a external jack to charge with USB type chargers, such as used for cell phone and of course a USB output jack so we can see and charge cell phone, hide ports under fuel cap to keep rain out.
    Okay I get a little out there with ideas, just the 18650/AA power would be cool.
    PS forgot to say, some cool looking lamps you built.
