DD XP-G2 on aluminium is not recommended.
How much is it pulling? 3-4-5A?? There is no point it going beyond 2,4A, and that is pushing it. Especially if you have a 1-mode in a P60.
No modes, so probably overheats fast. Im guessing battery time is crap (for the output).
A Noctigion Copper MCPCB would have made the output much better (1,84$ a piece when you buy two).
Instead of using a 1,19$ driver you could have used. A 6x AMC for 2,71$ (8x7135 if copper). The flashlight would be much more useful.
Or you could have used a 4$ Qlite driver, which would have made put the light in another league, especially if paired with copper mcpcb.
Yes, I know, it raises the price (with a few bucks) . But It would still be dirt cheap, only much better, brighter, more efficient, better battery life, more modes, not torturing the LED… Less heat issues… etc…
Also for people to consider…
The P60 (which you have to buy 3 of for best price) and the P60 pill. Costs a total of 6,22$
You could have used the NEW 612 and paid 8.96. (only 2,74$ extra) Which gives you a spare XP-G (if you wanted to go super budget, use that instead of XP-G2), a spare driver, better heatsinking, a marginally larger reflector, and a nicer host than a 501B. Review of NEW 612 here.
I dont mean to “talk down” on your mod. For about 10 bucks its good! But for 13-15$ it can be so much more!
And for those who wants maximum throw and can use a larger light. XP-E C8 can easily be bought for 6.99 Only 0,77$ more than 501+empty P60… Just an alternative for a cheapo build if one can live with a larger host and want more throw and better heatsinking for basically the same price… (that also gives you a spare driver and XP-E to play around with)
Just my 2 cents.
