Lumintop GT4

Ohh crap. Here we go again…

Me too.
I have enough big lights.BLF GT, Astrolux MF04 — MF04S ,Imalent DX80—R90C,Thrunite TN42—TN40S,Acebeam K70,Nitecore TM16GT.
So,I hope I don’t buy more.But looking at this new light,I don’t know if I keep my promise not to buy more. :slight_smile:

Interesting, I was not aware they were announcing these yet.

Yes, the goal is similar throw to the GT70 but ~20k+ lumens.

Not sure how big the market will be but it will be a monster that is for sure.

Yup looks great. Excellent heat fin setup on that light! :money_mouth_face:

I am proud of the thermal setup on this light, I have had the basic idea for a long time but just never got it implemented on a light before.

It is roughly ~6-7lb right now but it would handle the heat quite well.

Those fins are no luxury.

If it throws the same as GT70 but it’s much brighter I will skip buying GT70 and go straight for this one! Insane!

You don’t think 7x Boost HX in the 120mm diameter head of a GT would out-throw the original XHP35 HI GT? You may be right. I certainly don’t know. But, care to elaborate? :smiley:

EDIT: Roughly, each Boost HX would get a 40mm diameter reflector opening with very little overlap or a larger diameter with more overlap between them.

Both of these are kinda the same so I will reply together.

In my experience, a multi-emitter light will generally only have slightly less throw vs a single emitter in the same space assuming that the reflector cups are well made of course.

So… if that be the case, since the Boost HX has a MUCH better luminance than XHP35 HI, can it be true that 7x Boost HX would easily beat 1x XHP35 HI in throw?

Is this why you’ve been asking about overheating issues lately?

Yes, but only for a very short bit of time. The light will get hot quickly and the batteries will also empty quickly.

I want one!!!

Do you think going for a 21700 battery setup would be better for powering this monster?

Yes, this sounds reasonable to me, although not sure how much it would beat it, I would feel safer saying it would match it.

Wouldn’t that be equally true of the XHP-35 HI? Are you saying the 7x Boost HX would need to draw more power to beat the XHP-35 HI in throw?

Not this light in particular, I decided to keep this one Narsil due to the issues with the other light I am working on. Plus I have not seen the prototype yet myself, they just finished it the other day, so no testing on this one yet.

There is another light I am working on though that has been the reason for wanting to use Anduril. It is for sure not ready to be announced yet sadly.

If you think some details on it would help fix the thermal issues, feel free to PM me and I can tell you some there.

This has been debated from the beginning. There are arguments for both sides and I am split 50/50 on the matter myself.

It is not set in stone though, if people really want it to be 21700 even with the added weight it would bring and the fact most people do not have 8 21700’s floating around to use in this light, that can still be arranged at this point I think.

Well, the excuse of “most people” not having “8 21700’s floating around” is kinda moot when you’re already talking about hundreds of dollars for the light itself, don’t you think? I mean, if you’re gonna spend $300 for the light, might as well make it$400 and get all the cells, which can also be used in other lights if need be. Yeah, I know it’s recommended to keep the 8x cells “together”. Another option for some might be to use 8x 18650’s with sleeves.

2S3P 21700 maybe? ;)
