SolarForce RED p60 drop-in! (plus an XM-L drop-in)

Id be interested to know how the red filter works on a red led too

The Red will be deeper red and not as bright as it is without Surefire Red filter. But with red filter the dropin is still very bright. The red dropin is brighter than a LX2 with red filter.

Anybody know what the difference between surefire filters F26 and FM35 is besides $15 in price?

Since you couldn't bother to look 'em up...the F26 is a friction fit cover with a filter that you can flip up for white light. The FM35 has a locking ring which keeps it in place better and has a release tab for the spring loaded filter cover which is held along the flashlight body when not in place over the emitter.

lightfooted I appreciate the info. I did look them up however the description given doesn't really make that clear.

It seems a bit nuts to me, make a blue LED, cover it with phosphor to downgrade the effective temperature spectrum slightly, then put a red filter on it. Very inefficient, when red LEDs themselves are available.

I have yes to see a dark red led over 1 watt, if you liked the deep red of 640-680nm for night visions sake, then you'd understand.

For me the XPE red led is great, especially in a Zebralight H51FR. There are a couple astronomy buffs, and preserving night vision is important, so they'd rather have 10 lumens at 640nm Over 200 lumens at 620nm

The only "deep red" LEDs I know of are some off-brand you can get from LEDgroupbuy.com, they're listed as 660nm and come in 20mm stars at about $2 a pop. I have 2 on my bike and they can run at about 700ma max current, same as a Red XP-E (though they're probably not as resistant to over-driving). Looks like a Luxeon or Bridgelux package. They're not the best at focusing, though.
