XHP50.2 XHP70.2 WOW

Heat is manage extremely well in this light! Very shocking! May be the 50.2 is just not a very hot LED....

Hmmmm.... So this may be a sign that XHP50.2 is a good choice for multi-emitter lights that would normally have very short runtimes due to overheating.

Imagine replacing 4 to 6 XHP70.2 emitters with XHP50.2. The max lumen output would be less with the 50.2s, spec wise. But, they may actually run brighter for a long runtime than the same light with XHP70.2 emitters.

This would be a big advantage in a search & rescue scenario, if this turns out to be true.

I was thinking the same thing Madd. Was wondering what the X45 with 5000k XHP-50.2 might be like. A little more throw, a little more run time, and a nice tint. Hmmmmm. THIS may be a home run light too!

True. Then again, a host with deeper reflectors would help boost the throw. Both throw & runtime would benefit search & rescue.

Possible candidate hosts...
RC40
TK75
X65
TN40

I think 50.2 on the rc40vn gonna kick *** if it reach 300k lux or more..

It's funny that I was talking with my son on the phone while you were posting and we were saying the exact same thing!!!

Re: XHP50.2 WOW

Here is my prediction for the lumen/lux
rc40vn xhp50.2 .... 22000 lumen and 305k lux
rc40vn xhp70.2 .... 28000 lumen and 248k lux..

I'm wondering what a Lumintop SD75vn would look like with a XHP50.2

Hmmmm. That's 6 XHP70.2's, powered by 8 batteries..... I would go higher, NL

Hey mad, those are minimum numbers.. it might go higher..

sd75vn on xhp 50.2.? 5000 lumen? 330k lux..?? Big light can handle heat very easy..

i know you will buy a sd75vn because this light doesnt have build in battery pack, and powerful 50.2.

That's what I'm thinking.
Perfect search & rescue!

Re: XHP50.2 WOW

I forgot my infrared thermometer from work.. so i cant do heat test.. i will do tomorrow.. in the meantime, i have my olight sr95ut vn for 10 minutes at 20% mode... the light barely get warm...

Re: XHP50.2 WOW

Now that the X45vn has been shown to have 25000 lumens and 150K lux, are there any guesses why it has so much more output compared to the TK75vnQ70.2? The TK75vnQ70.2 has 18000 lumens and 165K lux, which is amazing, but it is lagging 7000 lumens behind the X45vn. Same amount of cells, same driver, LED's, ect. I'm just trying to make sense out of how the X45vn has upped the game so much in terms of output compared to other lights with similar components.

Re: XHP50.2 WOW

Not that I actually know anything, but I've come to the conclusion that the match-up between reflectors and emitters has a great affect on the outcome.
The sum of the parts can add up to more, or to less, than what would be anticipated given the individual elements.

In post#163 of this thread, I noted that the TK47vn was an overachiever with XHP50.2.

Perhaps the reflector design can sometimes enhance, and sometime confound the pattern of light coming from various emitters.
We all would expect this for lux measments, but maybe it also impacts lumens.

No, I'm pretty sure it's because of the unicorn blood.

Olight sr95utvn heat test. 4200 lumen / 300k lux. After 10 minutes straight on the 100 % mode, the head is 136 Fahrenheit,and the handle is 102 Fahrenheit.

Wow, Vinh! That's a lot of lumens for a single XHP50.2

Also, that's a good ratio of lux to lumen, making it a well-balanced light, IMO. l

TK47vn is now a legitimate 2*18650 light!
