Well of course it isn't as long, but I'm wondering on the more subtle aspects of the two, like reflector quality, beam pattern, heat sinking, the ergonomics of the two battery handle on the T21 vs the single 21700 handle of the T27, etc.

I actually like a long plunger style light for a thrower, so I wouldn't mind having a T27 with 2x21700 handle.

Isn't the factory 2500 lumen?

I think factories might be using the emitter lumens not the OTF lumens. Also seems like the lumen standards the flashlight industry has been using is 20% higher than ANSI lumens. Newlumen's numbers should be correct

I have stock version it is very impressive for stock light, and im not a rookie, im a veteran flashaholic!!!!

Could you please advise about the tint, from your eyes is it really 6500K or less.
I watch some youtube review , it looks like 5500K-6000K to me. Thank you.

I was under the assumption Acebeam's numbers were accurate. I guess not lol.

Acebeam lumen ratings are generally 15-25% higher than Maukka's ANSI calibrated sphere. Although with exceptions that the Acebeam H15 was actually rated a bit lower than ANSI. It's strange how even reputable manufacturers rate their lights so inconsistently. For example, Sofirn rates the C8F 18650 at 2,580 lumens but actually makes close to 3,200 ANSI lumens. Sofirn rates the C8F 21700 at 3,500 lumens but makes about 2,900 lumens. Olight is generally more accurate with their lumen ratings. The Olight H2R measures a slight bit higher than rated output but I think I recall there were some I measured lower. I heard Fenix are almost spot on but I don't have one to test.

My experience are the same. Numbers are even inconsistent from the same model light. I once measured a light too low. Sent the factory the picture. He then sent another picture of the same light on his "Pro Sphere" and the numbers were as advertised. Other times I measured a different model number from the same brand just like factory claimed. So...Who knows really. I think a specific sphere calibrated or not can still have the potential to read specific type of light beam and tint a little lower or higher.

I just measured a claimed 3.5Mcd aspheric light at 2.85Mcd (Turn On). However I measured at 7.5m while the builder measured at 20m. There will always be variables so I guess always take it for it is. Most important thing is how the light performs to the eyes. A nice beam with the right tint usually impresses more than numbers for me.

You were the one that bought that 3.5m aspheric + wavien collar Gigathrower on BLF?
No but a close local friend did ;-)


I think even measuring the thing at 20 meters is a disservice. Agree


A light that tightly focused won't even fully collimate until way further out than that I feel. I think so too.
