P60 heat limit?

Hi BLF! I am excited to be planning my first P60 style light (a Solarforce L2P with a XM-L drop-in) but I need some help for when I choose my driver specs… I need a light that can be used on the highest setting for extended periods of time. Does anyone know the highest output that I can run continuously without risking component damage due to heat building up in the body?

Any thoughts would be appreciated!!

It's good to have you here, benz!

Why are there Lambo doors on that MBZ?

To the OP, it you go much over 3-3.5A on the drop-in, your switch will likely be the weak link in the chain, not the emitter, especially if you run for extended periods.

Plus if you go over 3.0A, your battery runtime will be pretty low, and you will be changing batteries more often.

I would be very surprised if your eyes would be able to tell the difference between a drop-in driven at 3.0A and one driven at 4.0A. If it was me, I’d use one regulated at about 2.5 to 2.8A

Thanks! and thank you trooplewis. I only want around 400 OOF lumens which, if what Ive read is correct, I should be able to get from a driver putting out around 1000 to 1400 mA on high. Does this figure sound right? Could that be run continuously without overheating?

I have no idea, but you have to admit it looks pretty sweet!

400 OTF ! a 1.4A driver will take care of that for you … Give you excellent run time , very little heat related issues , and you will not have battery issues and I usually get around 460 to 480 Lumen at 1.4A , which is plenty most of the time out of a P60 .

Great news! 400 may not sound like much but I have an Olight S65 that has a similar mass to a P60 host and it can’t maintain 700 OTF lumens without thermal regulation dropping the power level down to medium so I thought I should try to stay conservative!! Plus I guess the beauty of the P60 arrangement is I can upgrade for more power if needed. Thanks again for everyones help!
