BLF GT Proto. Review. Work in progress. update 6.8.17. Post 69. Run time test added.

Nice beamshots
Ouch so harsh cold that GT, but dang bright :slight_smile:
Though I love the Q8, C83 and OL tribute light beams a lot as well.

Wow, wow, wow and just wow!

[Lovely tint of the Q8 though]

Q8? is that the BLF Q8? havent seen anyone posted beamshots of it.

Djozz has posted several beamshots, don’t know exactly which post of the almost 10000!

I’ve Posted beam shots of the Q8 before. Not sure where though.
The tint of the GT is cool and its unknown to me what it is. The GT will be getting a warmer tint in the production lights.
I should of mentioned these pictures of the GT were taken with the black mark on the led. This will be looked into today.

:person_facepalming: and they forgot the pocket clip

Lots of beamshots of the Q8, just check what we posted, it is in the OP
Most of us posted beamshots but it stood out to me here, without even seeing it was our Q8 at first :smiley:
Can you imagine a nice NW XHP35HI GY beamshot?
Already it is impressive.

Just a couple of pictures with big brother posing with little sister.

The MCPCB really is that big. Yes its the Q8.

A C8 reflector sitting on top with a P60 and S2+ reflector out front.

Yeah i saw few beamshots but all indoors, and i could probably missed few others too they are all buried somewhere in the thread. Cool to see Q8 outdoor shots like that beat my expectation. ok back to GT.

The “chunkyness” of the GT reminds me of the BTU Shocker.

The Miller, if you look up close at the last pic of MRsDNF of the different reflector sizes, you can see the steps milled on the GT’s reflector outside surface, I bet those are the reason we see rings on the wall beam shots from inside the reflector, I am guessing that maybe they are removing too much material on each pass of the CNC machine…

The most impressive beam shots of a reflector light I have ever seen. Thanks for the trouble Steve. Lumentop along with our BLF designers has stepped to the front of the pack with this one. Step aside Thrunite, Olight, Fenix, Jetbeam, and Acebeam.

Can’t stop laughing on this !!! :laughing:

As I am old enough,I prefer cool white tints.I can look better with them.So,is it possible that I take one with CW tint?

Nice pics MRsDNF!
Hahaha with the C8 reflector on top :smiley:

First response to CW option is “no just one led choice to keep it easy” but given the difference of 10% we could talk about it in the team, will come back to it.

The run time test below was carried at with Kaidomain protected 3500mAh batteries. 30Q run time test was also performed.
There was only a few percent difference in output between the two different batteries with the 30Q just ahead until the 45 minute mark where the KD 3500 pulled ahead.
The low voltage protection kicked in at the 72 minute mark while the 3500 KD batteries lasted until the 94 minute mark before low voltage kicked in.
The rested voltage of both types of batteries was around 3.5 volts.
I’d have no hesitation in running this type of protected battery in the GT with my tests.

I was thinking that the GT was going to have some sort of regulation like the K70… :open_mouth:

Runtime graph credit goes to member Selfbuilt on CPF!

I’m not sure Alex. Maybe the electronic guys can chime in.

K70 use bust driver therefore it must be regulated, while with buck driver like in GT performance will drop as voltage drops. But this testing was with short tube and 4 batteries,
so with 8 pcs runtimes and voltage drop will be twice better, 180+ minutes with 3500mAh batteries

It really looks like a great flashlight, I regret not having been listed on time, the lights designed in the forum are always special and unique.
