Hi all,

Just got a TN31 XM-L2 in the Neutral White. Does anybody know what bin the LED they are using in the neutral white version is? All the marketing says it’s a U2 but that may just be the cool white version. Is it really a NW U2? or is it like a T6 or something?

Just curious really as it seemed that XM-L2 U2 NW’s are pretty rare.

Ill never understand the need for neutral white on thrower lights.

you like cool white ? or wharm white ?

for my bikelights and outdoor i like more warm white

inside buildings i like cool white

for throwers cool white is the way to go, throwers are rarely used in close usage scenarios generally, if you need close range, edc with NW is alot better ofc but throwers, not real use at close range so tint is not issue, and to know that cool white emitters throw better generally you got the idea.

Had it out tonight along with my modded Catapult V3 that has an XM-L2 U2 1D. The TN31 with the NW was still brighter, though marginally. I actually didn’t mind the NW in a thrower, especially after comparing it side by side, the CW seemed to illuminate the haze/fog in the air a lot more making it harder to see the distance, and the NW TN31 certainly didn’t have a problem out throwing the Catapult. Plus the NW was just more pleasant to walk along with, this was in the woods mind you.

I was just a bit curious as to if ThruNite was actually using the U2 bin in the NW lights. I know in the old XM-L version of the TN31’s the CW was U2 and the NW was T6, can’t seem to find anywhere that states if that is the same as the XM-L2 TN31’s, ThruNite just mentions U2 over all the promotional material for the XM-L2 versions.

You are comparing inferior light to the 31 bro…even in NW.

Edit, for walking usage, i guess NW would be better, i always imagine using throwers for max distance, and not up close.

I prefer NW. At night when using a thrower my aim is to illuminate and see things far away. CW isn’t much brighter than NW when you look at a light meter. CW doesn’t actually ‘throw better’ than a NW. At the same lumen output they would throw the same distance. CW just happens to be more efficient but when you look at the numbers it’s only really 10% brighter at most. It looks brighter though because it’s more harsh and glaring. CW however produces a lot more glare than NW. As a result the beam itself looks brighter and glaring and as a result contracts your pupils meaning less light gets in meaning everything becomes darker. So not only does CW produce more glare than NW (which is why some people say the light is ‘harsh’), it has a worse colour rendition so it’s harder to make out what I’m trying to see 500 meters away.

A CW thrower is a better ‘wow’ light whereas a NW thrower works better. When you’re actually trying to make out things at longer distance you need all the help you can get and CW is counter intuitive.
