    Default Ferei W150

    So I saw this little light and decided to give it a try as a modder. Got it yeasterday. In stock fashion, it is a cool light. However, the magnet is not strong to make it turn on. Damn! I have contacted them and we will see if I ever get one that works.

    Looks interesting. What mods do you have in mind?
    I guess a XP-G would be a good starting point.

    Not sure what I wanted to do... Just thought I would get it and see. I was thinking XML, but it would have to run on 2 CR123 and would only get about 30 minutes run time... May be use as a canister light head???

    OK, so me have news good... Magnet in light unstrong enough to work light in high tech self intellectual lighting system...

    OK, really... I got the light to operate with the stock magnet. For some reason it just started working. Sometimes I have to hit it to make it work, but it works. I tested to 265' max for a total of 8 hours or so and it was totally dry after the time. Overall a great light for the $55. Tail cap amps showed about 0.76 amps and battery voltage static was 4.0 volts. I have a 16mm XML coming for some playing around along with a kaidonaim 18mm driver board. This should make an interesting build!

    Will have to wait, going diving in Cozumel later this week.

    Back from Cozumel and dove 14 dives with the light attached to me. Max depth 134'. I actually used it on two night dives. The light performed well. I really like this little light. This one will make it to tlslights.com inventory...

    Does this mean you're going to start selling the light on your website? Did you do any modifications to it? My "small" light is a UK SL4 with the DX R2 dropin. I'm looking for a smaller light though.

    Yes, I will be carrying these. I have not modded one yet, but I have a buddy who wants a UV one so that will probably be the first. Price will be $55-60 plus ship and Paypal. The light comes with 1 18650 battery, single cell charger, lanyard and a spare set of orings. It is manufacturer rated to 150m and I have personallly tested to 265'.
    Thanks

    Hi 350,

    I'm anxious to see what else you've done with your W150. I just one as well, along with an XML T6 light.

    I took a stock one diving in Cozumel then I built the XML one and did not do anything else with it. I still have both in the garage!

    I got my W150 from eBay for $31 - shipped!...

    And I just got it in the mail today along with my XML T6.

    As bright as the Ferei is, I'd like to convert it to the XML. 350, any news on your project?

    I guess what I want to know is that if I stick an XML T6 LED star onto the stock Ferei driver in the W150, will it work? What kind of burn-time am I looking with this modification?

    Yes, you can put an XML in the W150... However, the stock driver will have to be replaced if you want to use the XMLs brightness. The W150 is only about 1 amp driver. You need 3 amps for the XML. Use the kaidomain P7 2.8 amp driver for that. They have a 19mm drover that will work. It's about $12.

    Oh, and get the XML mounted in the smaller board... Not the full-sized star board.

    Thanks Hector! Exactly the info I was looking for The LED I got was on a 16mm board. Another question though: I noted that the hotspot of the XML is a bit floodier than the current Q5 using the same reflector. Did you note the same on your modded light and was backscatter a subsequent issue?

    Yes, the reflector being so small gives a floodier beam. I never dove mine so I can't speak for backscatter.

    is the reflector the same size as a w200 one ?

    are the quality check better than the W200 ones, since i wish to change of model eventought i did build some 2*18650 with MC-E or X-ML. I have 10 of ordered and none were watertight at arrival. Some even took water in a bucket, the others leak in my test pot when i put them in shallow water. They all need a oring job !

    So, can i be confident with W150 or not ?

    I got my 16mm XML T6 star yesterday, then it got me thinking: If the W150 driver is 1 amp, and the nominal current for the XML is 3, I would theoretically get 1/3 the max lumens but 3x the battery life? So, if the XML T6 is around 900-1000 lumens, could I get 300 lumens for 6 hours in lieu of the current W150 200 lumens for 2 hours using the same driver?

    At 1A, the battery life would be 3x longer than if you ran it at 3A, but would be the same as running the original led at the original current of 1A. You would, however get the 50% increase in output.

    The W150 uses a single 18650, at 2.2-2.6 amp-hours. The battery voltage is a little higher than the LED voltage, so a buck switching driver could give you a little more output current that input current, so maybe you get 3 A-h into the LED. At 1A, you'd expect around 3 hours. If the driver is any good, with an XML you will get full (300 lm) brightness until the battery is pretty nearly dead, then it will taper off fairly quickly. A higher voltage LED would make the brightness start tapering off sooner, but the ultimate life would probably be similar.

    Sounds like I'm good to go then - longer battery life and a slight increase in brightness. I guess as long as I don't keep my expectations too high, this would be a quick swap - then maybe when the right driver comes along, the swap will be complete.
