Hi all.
I spent a lot of time delving into the world of LED flashlight mods a couple of years back, then life got really busy.
I'd like to get back into it again now.

Back then P7's seemed to rule the roost for maglite mods.

When I look around the forums now, it seems not so much. From what I can see, the Cree XM-L seems to be the standard now. I also see other Cree options, but I get lost in the model numbers.

So yes, I have searched the forums, but can someone please help me get up to speed again:

- is the P7 superseded for high lumen maglite mods?

- if so, what's the current state of the art? XM-L, SST-90?

- does the XM-L have to be driven beyond specs to get the high lumen outputs?

Thanks in advance people :)
 
I've also over-driven the XM-L and as long as you keep really good heat sinking, they're safe up to about 4 amps using a well heatsinked star mounted XM-L. Continuous use at 5 amps or more will burn the phosphor around the traces though. But my best guess would be if you get 1000 lumens at 3 amps you might get 1200 at 4 amps and corroborated using a ceiling bounce and light meter, that's extrapolating from Cree's data sheet for the T6 bin too. It's slightly brighter if you compare them side by side from 3 amps to 4 amps so my guess 1200 lumen guess would be in the ballpark.

But in all respects but one the XM-L bests the P7. The one caveat is color, everyone here will tell you that in a reflectored light the XM-L will make a noticeably yellow hotspot with a blueish spill. It has a weird color distribution. The P7 lights I've had always had a pleasing creamy white tint that was even across the beam.
