LED Houselights

[AKCamper]

I am looking for LED houselight replacement bulbs.
A friend of mine was saying that i cant put my hands on one for under $15.00.
I told him he was wrong but i have no evidence to back up my statement, help me out here.

I am almost positive they are crap though.. Almost because I have never tried them before.. I highly doubt you can get quality LED lights at that price.

I think this thread should be in Fixed Lighting btw..

Your friend is more or less correct. Some suppliers & prices:

http://eliteled.com/products/lightbulbs.html
http://www.ccrane.com/lights/led-light-bulbs/index.aspx

But if you do not mind getting crap:

Please note a shorted out bulb CAN BURN DOWN YOUR HOUSE.
For 2 years now some Canadian electrical utilities have been distributing LED Xmas lights to encourage conservation. The manufacturers have provided samples which obtained CSA approval. Unfortunately the production units are nowhere near the same quality and all the lights have to be recalled. Buyer beware when purchasing from unknown sources!!!

EDIT
BTW stay away from the 5 mm showerhead variety. They last from 1 week to 1 year (nowhere near close to the 100,000 hour/10 year claims).

At least they are all UL listed. Unfortunately they are all of the 5 mm variety.

wow, this is dissapointing. You would think with as cheap as they are selling super bright flashlites they would be selling and making some decent LED house lites.

 

[coolwaters]

lol when i saw the title i was like "that would be the biggest LED ever lol"
also with the biggest heatsink.

edit: i thought i saw lighthouse...

Yeah...same here. I have direct applications for LED lighting in progress, and the available products are *so bad* I'm having to build my own fixtures from scratch.

IMHO - I avoid bulbs like these because the cheap power supplies cause an annoying flicker. Not rectified I believe.

Then again, with the main serious application of LEDs on this forum being flashlights and light sabers it's no wonder........

I had one of those multicolour LED lamps fail, quoted as 50,000 hours, lasted less than 1000.

I took it apart, suprising to find a full wave rectifier hence 100Hz with a 50V100uF cap, zener circuit, an IC and some transisitors.
Also a crystal oscillator was connected to the IC. (probably for the colour changes)
The voltage was dropped by means of a 684 , 400 Volts capacitor.
across that cap was a 1/8 Watt 150 k.ohm bleed resistor, (well under rated, although no signs of stress)

Good to see that there was an 1 ohm resisitor in one of the supply leads.
Then a MOV was across the input terminals as well.

By putting 22.5 V dc on the 100uF cap I managed to get the LED's going.

The miniature board is very awkward to work on, so my guess is that the rectifier or cap has failed.

I can add some photo's if anyone is interested.

If you want the same output as your household incan bulbs then forget the cheap options. You'll have to pay big $$$. This is just an example:

A 75W incan bulb will give around 1000lm. For that you'll need 2 conservatively driven (for decent lifetime) SSC P7's. ($40) Add some heatsinking, decent electronics etc, and then add some profit for the manufacturing company and that's at least $100.

A "daylight spectrum" tri-phosphor fluorescent bulb would be much more economical and give better colour rendition.

 

[AKCamper]

Ouch, $100 that sucks. Untill they come out with a cheaper version i think i will just stick to the fluorescent bulds

 

[Melchior]

THEY LIVE (err exist)

$15, is probably too low a figure.

However around $20 can get you a light good enough to use for a reading lamp or desk light.

Also avoid ANYTHING 5mm LED. Junk Junk and MORE JUNK!

Power Emitters are the ONLY way to go.

Lights like:

Possibly:

Large heatsinks are a must, the electronics might work without creating alot of heat, but they LEDs will fail if they overheat (as will the electronics).

If you look into the future, a combination of cheaper LEDs and mass production should bring this price down a lot. I reckon that in 5-10 years time it should be possible for under $15.

 

[AKCamper]

LOL yes, i looked into the future just the other day through my grandmothers old crystal ball and i saw an LED houselite for $12! Amazing! LOL

I saw some 1.5 Watt colored bulbs at Tesco, but for something actually useful with sufficient Lumens I think the price is still higher. There are suppliers that offer cheap many LED bulbs using cheap LEDs. When I say many I mean very many small low power LEDs all together. A really good LED light that can replace a 60 Watt bulb may cost more than $50. Look for the type of LEDs used, CREE, SSC, SEMI are all good. Look at the Lens Angle and light color.

If you are interested in house LED lighting you might want to look at what some are doing over at CFGGREEN. Neat stuff, but I am sure it is not cheap!

Check Walmart. I recently bought a couple of 1.5 watt l.e.d. screw in lamps for $5.50 each. They were warm white and claimed to be as bright as a 40 watt incandescent bulb. I put two in my bathroom to replace the heat lamps on the ceiling. For spotlights, they do pretty well. Walmart also had other l.e.d. bulbs between $5.50 and $30 in cool and warm white. Walmart had one that looked like it had three Crees for around $30. Home Depot has l.e.d. recessed can lighting now. The 4 inch kit was $40 and the 6 inch kit was $60 or $65.

The led bulbs you get from the Warmart is really so cheap, how about the brightness?

 

[eyeeatingfish]

So far LED houselight bulbs havent really caught up. I think you might get the equivalent of a 40 watt incandesant at best now, maybe a 60.
You can get some others that make great night lights or small lamp lights. I posed a review of two that I bought here.
