Flashlight Modding and DIY Parts

I just create ny first R5 drop-in with these parts:

I have to admit that i'm pretty surprised of the result. Considering the 1A input, it's really bright with a good flood and a nice hot spot. With 1A i have no heatsink problem and a longer runtime. Probably one of my best drop-in.

Nothing like DIY , + the XP-G has matured nicely .

I think the ones available now , are simply better than the ones from 12 months ago ..

Cree did have problems with the XP-G

You're damn right.

I compared the R5 (1A current) with an XML (3A current). Obviously there a differnce but not so big as you can expect.

Ive been getting into pushing the R5's with 1.5A's and higher and when they hot close to 2A they start giving XML's a run for the money. But heat is still an issue tho, But if you stay below 1.5A they do well even in small hosts with minimal heat issues.

I have similar setup in my L2i.

Pill & LED are from Solarforce dropin but driver is the same. (although I somehow got the AK-47c)

Makes a good general use light and PWM is nicely very high!!

I have been experimenting with XPGs lately as well. I have a couple P-60 drop ins running with 5 7135s at 1.7 amps and one with 6 at 2.0 amps all in 501A hosts and they have been holding up great and are extremely bright even compared to the XML. The XPG really is a great little emitter, highly underrated for a long time.
