Most regulated lights will still have thermal regulation though, so only put out a constant brightness after thermal regulation has balanced.
This is a nice light. It’s like 20x better than a convoy. Worth the money IMHO.
I think I’ll get one. Similar performance to the Convoy M21C/D, more compact, and looks amazing.
It’s a boost driver. 6V for XHP70.2; 12V for GT-FC40.
Ah yes, XHP70.2 6volt. How’d I miss that. Thanks.
Stephenk, the hotspot is 23.7° and the spill is 84.9°
Thanks, LuxWad!
I'm glad you figured it out. 
Thanks for the info. I’ve ordered one. Sustained brightness for size is very impressive.
I love this light!
I really like your review style RC!
Short and to the point and if i didnt own it this would be the review id want to read. I dont need 2,000 words when 200 will do!
I have aluminum gt fc40 3000k and a Stainless Steel xhp70 4000k. and i love them both equally.
There was a post on reddit to the effect that acebeam were working on a smaller form factor of the E70
I am not an expert by any stretch but if it is a single cell light the answer is yes. If it were a 2 series cell light it would be a buck driver. Anyone please correct me if I am wrong.
Yes, XHP70.2 can be wired in 6v or 12v configuration. GT-FC40 is always 12v. If it’s a single cell, it has a boost driver.
Two series cells for XHP70.2 could be buck, linear or even direct drive if wired in 6v. Most XHP70.2 lights I’ve seen are set up for 6v operation.
I updated this review.
Most importantly I added to the very beginning, "The flashlight images in this review are from Acebeam, and the images are being used with Acebeam's explicit permission."
My opinion on this light has not changed. Probably best design I have seen. The light is pure flood with no hot spot. You either love it or hate it. I would have liked a bit more hot spot but that’s just me.
It looks different but the design doesn’t look good w.r.t. the housing. Surely all those holes will fill up with dirt. Not sure how others use their lamps but mine are not kept in a dustless IC manufacturing facility. They get actual use in and around the house, on bike trips, etc., and any holes and edges will get filled/get a layer caked on the side, over time.
Is that right? I just read in another thread that you have/had over 100 Astrolux lights (I think it was you). And I imagine you have many other lights too. So saying this is probably the coolest looking light you have is pretty freakin high praise. Makes me think I really need this light in really any of the exotic metals. It’s a little on the larger side from the looks of it, and the UI is so-so, but damn is it a pretty light. I have been resisting this but Acebeam has gradually turned me into big fan and the looks of this light is a prime example of why, on top of always insisting on efficiency too. They even stepped up on this one and added a High-CRI option. That’s the one I want I’d want and it’s out of stock so thats probably for the best, but still, I am getting to a point where this is almost a must-have. I think I heard they are coming out with an 18650 version. Don’t prefer that battery, but may welcome the smaller size. What are your thoughts on it after owning it for 6 months?
Hi Artie,
Didn’t know you bought these. How are you liking them if you still have them? Still can’t seem to get over my infatuation with this light.
I was reading from the beginning when I asked my question, but I see you literally just a few minutes ago answered it. Just one of those things I guess. 
This light really shows they are thinking out of the box. This is commendable.
That’s great to hear. I’ve heard others say that because if the dual tube design, it doesn’t ever really feel hot. For a hot rod, that’s a pretty nice unexpected feature. Ultimately I prefer 21700 so I may just pull the trigger on this if it becomes a si le again.
Thank you for your thoughts.
