Convoy L21B - which LED to get?

I am mainly looking for maximum throw.

Thanks.

this might help; read through the comments too: https://www.youtube.com/watch?v=96IkzoYiiyw&t=50s

Or this; this dude is a member here (Funtastic): https://www.youtube.com/watch?v=EfLkExL8NcM

It seems to be that the sft40 might be the better choice after reading funtastic’s comments. Raccoon city – another member here – is a fan of the sft40. Maybe search for reviews of it here too?

Osram CULPM1 is the best for range at 1345m. The CSLPM1 isn’t focused correctly giving only 1250m instead of 1450m, the 5A driver is pushing 5.7A and killing some LEDs, not recommended. The SFT40 is a great all rounder at 1200m, it provides a wider beam at a very small reduction in range.

The PM1 has a more neutral tint and for that reason alone I prefer it.

If you make a custom gasket for the cslnm1 or use the black PM1 gasket you’d get at 1450m. You could get the cslnm1 green which can handle the 5.7A, and with the PM1 gasket you’d achieve 1700m

Yep, I like SFT40 emitters.

They throw quite well, and they can provide a decent amount of spill if a suitable reflector is used.

If you don't care about spill, there are some other emitters that throw a bit further, but they don't have nearly as much spill.

Which others besides the PM1 and CSLNM1 if focused correctly? I'm curious

Our posts crossed.

I didn't see your post until after I posted mine.

I don't know what other emitters throw better than the SFT40, but I'll take your word for it that you do.  :THUMBS-UP:

Thanks! The CULPM1 sounds good. I don’t want the larger hot spot of the STF40 because I need to thread the beam through some trees to see over some open water and don’t want a lot of light reflected back from the trees.

That youtube video of mine linked in the 2nd comment will give you a pretty good idea of how large the hotspot is, or even my hunting guide at the bottom of the page

Sorry about that.

I should know more about different LEDs, but I don't.

I kinda know the ones that appeal to me, but I don't know much about most LEDs.
