Lumintop BLF GT94 ( 4 x SBT90.2, 1.65mcd ) NOW AVAILABLE @ Neals: code NDGT94 gives $ 150 off

Ok, another thing to keep in mind is that it is around ~5700k vs most other CW lights that are 6500k, so it will naturally look warmer then those if that is what you are comparing it to.

Thanks Texas_Ace.

So are you saying that the GT94's Luminus SBT90.2 LEDs are cool white in 5700K where as the GT4's XHP70.2 LEDs are cool white in 6500K?

Here are 2 beam shots, shot against different background colored walls. I may have misinterpreted the beam color based on the wall colors.

GT94 beam against a beige colored wall.

GT94 beam against an off-white colored wall.

5700K is in the CW range. NW goes up to 5000K, >5000K is generally considered CW, see here: https://flashlightwiki.com/ANSI_White

Correct, the GT4 is 6500k and the GT94 is around 5700k, maybe a bit closer to 5500k. Side by side you will be able to see the tint difference.

Picture looks fine to me given they both have a bad color temp setting (normal for a auto setting).

Although the SBT90.2 is not made in anything but CW, so it is basically zero chance it is anything else. Sad for me, I wish they had a NW version.

I will say that the GT94 tint is acceptable even to my CW hating self.

Got my light! Can’t test it though because I accidentally ordered flat top VTC6’s instead of button top :person_facepalming:

Edit: Soldered some tabs on the top of the batteries and got the light to come on. The only words I have are that this light is insane!

Check out my beamshots here! There is no comparison between the GT94 and the other lights lol GT94 vs some of my other big lights

I’d like to see some beam shot comparisons next to the GT4 at about 200 yards.

There is some #'s from a good source showing a 26% bump in candela for swapping an OP to SMO, Matt Smith (VOB) with a Convoy L6 XHP70.2:

Matt's vid here: https://www.youtube.com/watch?v=TRp8WxJsivw&t=213s

130 kcd to 164 kcd which is a 26% bump, but think the variations from LED to LED, light to light, reflector to reflector is significant.

Yeah, that is a bit of an outlier in my testing, I think that the combo of the XHP70.2 and the VERY heavy OP on that reflector played a role in the results.

Still, I would not be shocked to see 15-20% gain in lux with a SMO reflector in the GT94 at the cost of the slight donut hole returning.

I will have mine Monday or Tuesday. Will do the test.

Mine has Oranges in the reflector…IS THIS NORMAL…LOL…i havent got it yet…still says returned to sender…

I’ll have mine tomorrow.

Are we going to have to request the smooth reflector or is Neal just automatically sending them out to all of us who got the first batch?

We should know more once the reflectors are made but I am guessing they will be sent automatically but don’t quote me.

Wow! Can you tell if the beam is emitted from an SMO or OP reflector 1km away? Maybe because the OP reflector emits a weaker beam?

Are you sure? I don’t think the driver allows you that

It will definitely allows you. I did disable the temperature controls on my GT, GT90 and GT4. Will do my GT94 as well later today. The courier will drop it off in the next two hours.

I designed the driver (and TomE did the firmware), pretty sure it allows you to recalibrate or disable the thermal control :wink:

It explains how in the Narsil instructions.

at 1km you will not be able to tell much as it is hard for most human eyes to even see that far clearly.

Although my statement above was a more general opinion I hold, there are exceptions to it of course but in general I pick the OP reflector when available.

In this lights case the SMO reflector has a slight donut hole (simply due to how large the die is on the LED, not much you can do about it). I am guessing the OP reflector would basically eliminate this which would be nice for everything except max range usage IMHO.
