I bought a 50pk of the leds looks like I need a cheap host, any ideas?
None of the links above work?
Here is the Mod steps for this Pailide GL-037-13 with the Neutral White emitter.
- First carefully push the reflector, lens, plastic pill and driver from the front of the light head out through the back. (with thumb) and dissemble the components as seen in image # 1 below.
( Note the replacement N/W Emitter next to the original Straw-Hat generic LED & board.)
- Next unsolder & remove the original LED,( Imagte # 2) then drill two 1/16” holes roughly 1/4” apart as seen in Image # 3. Bend the tabs on side of the emitter ( # 4 and # 5)
and re-solder the driver wires to the tabs of the emitter on the otehr side of the star-board.
As the driver is only drawing 0.60 Amps and puts out only 45 to 55 Lumens, the emitter is not driven hard enough to require an aluminum or copper star, though if you with to upgrade the driver to a more powerful multi-mode boost driver (as in the 20-mode 7880 Driver) you will need to mount the emitter on a metal star for more heat dissipation. (and maybe a custom metal pill for better heat sinking)
In Picture # 2 below:
- file or sand down the base of the reflector roughly 1/16” of an inch, and drill out the opening to roughly 3/16” inch, to accommodate the larger emitter. (Image # 1. and 2.)
Re-assemble the flashlight head, ( image # 3.) (note that i placed two blobs of solder opposite of each other on the negative ring of the driver for better contact points for turning on.)
There you have it. 
(image # 4)
A simple mod that costs less than 2 bucks in total to get a simple, EDC light with a great Tint, with just enough output for close range work that tail stands and not a big loss if you loose one.
For a little more time and cost a multi-mode driver can be added, for more output and modes. ( as in the 7880 driver possibly. )
Thanks a lot for the mod!
Your welcome. I am doing another fo these lights with a multi-mode driver and XP-G2 emitter to see how it works.
If those lights are similar to some cheap AA lights I’ve modded, and if you need/want a pill instead of the plastic collar, take a look at the series of threads that ImA4Wheelr did like this one:
Thanks for the link.
Is this still available anywhere.
Most of the place they were available seem to have been sold out for a long time,
only here maybe: http://loeldeal.com/goods-1750-Pailide%2BGl-037-13%2B3w%2Bcharge%2Bstrong%2Blight%2Bflashlight%2Bcree%2Bled%2Bwaterproof%2BLed%2BFlashlight.html
Just got a refund from loeldeal…the item is not available anymore…
Very sad
Wow…Brilliant and simple mod…excellent!
I discovered that too when i went to order more. hopfully it will show up again somewhere.
if it does i will post the update here.
Really sad.
How many were you looking to buy from them ?
Just tried this mod, with one of the police lights. Worked exactly like you pointed it out.
Driver looks the same there is just an additional spring underneath the pill for making contact with the body.
This light pulls very little current around 0.2A on an eneloop, so this light has a long runtime.
It lost a bit of “throw” but the blue tint has gone.
LEDs In neutral white ordered, I hope these perform a bit better than the ones I had laying here.
hows the tint uniformity across the beam?
a lot of those leds i have seen in the past were poor in that aspect.beamshot looks good.
I did testing on that. and interesting that these low-cost Luxeon clones are almost as uniform throughout the emittance angle with the tint as the Nichia 219’s are, and MUCH better uniform tint & color rendering than most CREE emitters including the NW XM-L2.
Here is a photo showing the tint shift in the CREE XM-L2 vs. the Nichia 219 vs. this Luxeon clone:
Interesting. I never tried this mod on the 3W police hosts yet.
Looks like i have another budget-project light is in the works. 
great.will pick some up.
True budget light mod, very impressive sir!!! Thanks for taking the time and documenting everything, I really appreciate it!!!
