I think I read somewhere that HL will be using P2 bin emitters. If that’s the case, they should be getting 21k lumen sper Newlumen’s TA_tube measurements. That’s actually not far off from their 24k claim considering the majority of flashlight manufacturers way over specify their lumen ratings. It seems only Olight/Acebeam/Thrunite have been pretty spot on with their advertised lumens. I found even some premium brands like Zebralight overrate their lumens much more than that after testing it with my TA_tube.
HL had a 4000k 80CRI option for the GB. I bought both the 4000k 80CRI and 5000k 70CRI. The 5000k version was 32.3% brighter than the 4000k.
I really liked the tint on the stock 4000k 80CRI, which was almost as good as my 4000k 219b 9050. The tint was actually closer to the BBL than the one TA was using from Arrow. But the Arrow 4000k was much better than the same 4000k 80CRI from Mouser which is horrendously yellow.

I don't think that they are using new P2 led. All my MT09R has oryginal led so it looks like in new MT09R LED has higher VF or lower bin than thoese from group buy.

It’s hard to pull any useful information from that video (that we don’t already know), but one thing I noticed was that the 4 battery springs on this 70.2 version are not bypassed at the factory. This would seem to indicate it’s definitely not going to make 24000 lumen. I wish they didn’t over rate it so much. Still, it seems way better than the original light.
I’m not used to complaints about only 1100 lm gains.
BTW, seems like Samsung 20s is a good cell for this light.
It can be had from Vapcell (Vapcell Black 2000 mAh), but it’s a bit expensive.
Is there a better source?
I did ceiling bounce output sag measurement on the output for new version Haikelite MT03 that I estimated to be about 12k lumens compared to my other lights. No temperature chart here, I was lazy to use thermal meter, it is getting very very hot in one minute. With freshly charged batteries and in about one minute, its output dropped from 12k lumens to 11k lumens.
All true, but the problem remains that the 24000 lumens declared are not achieved, even for technical reasons of the 3 xhp 70.2 leds or something wrong? Thanks.
Haikelite and many other brands love to do that. I guess they want to attract uninformed customers with higher lumen number.
For us, we buy knowingly it is unreal theoretical startup LED lumens, it is not ANSI OTF lumens. They never declared it is ANSI specification to anyone.
It is not necessarily a bad thing for us. If they can earn extra money from uninformed customers who don’t really care about lumen, they can stay in the business and continue to come out new and innovative flashlights, it is win win situation.
