Hi guys, i recently bought an ultrafire wf-502b, XML-T6 flashlight which is rated at 1000 lumens on a single 18650 (3.7v). The light output is awesome but i don't think it is a 1000 lumens, i'd say around 700-750.
So... i've been searching around to find a brighter drop in. I'd like to keep the ultrafire as my host.
i have an 18650 extender tube aswell if the voltage of the dropin is slightly higher, I also have a lot of 3.7v 16340 batteries which i wanna put to use...
I'd love to hear some of your thoughts on what drop in is truely very bright!
I just received an Ultrafire WF-501B from TMart. I got it in 6 days, cost $14.99 and draws 3.35 Amps on an unprotected cell. I don't have any really good protected cells, but they draw 3.0 Amps. It is VERY bright.
The famous Manafont/Ultrafire 3 mode drop in is by far the brightest most popular drop in on the site as long as I have been around, unless you want a custom made one.
I make them and "nailbender" on CPF does also or you can make one yourself, here are a couple how to links to look at.
There are quite a few advantages to custom drop ins. You get many different options such as:
1. Any emitter and tint you want.
2. Maximum drive current usually from 1 amp up to 3.8 amps for an XML, but the sky is the limit here.
3. Mode selection my favorite is a custom 5 mode from moon low .002 amps to turbo 3.5 amps 1 to 900 lumen with the press of a button.
4. No visible PWN if that is bothersome to you it can be all but eliminated with a custom driver.
5. Reflector option SMO smooth or OP orange peel and different sizes as well.
6. Potting, you can have the empty air space filled with heat conductive adhesive to increase the heat sink abilities and increase strength for say a weapon mount light.
7. Spring size and position, don't laugh P-60 hosts vary so much different spring sizes can be required and heavier gauge spring flow more amps with less heat.
Basically anything you can think of can be done on a custom build, plus doing it yourself is quite fun and satifying.
If you can solder you should really try building one yourself.
