It would take a psychologist a lifetime to poke around in that mind of yours Dale. A light pyramid using the longest throw led flashlights on the planet, unreal. It’s a darn good thing you are a photographer because we want pics!!
I will probably install xhp35 hi E2 1A in mine (when i get the GT , and when i get the leds) , it should be a little cool for my taste , but i will live with it
I hope this won’t open a inter-dimensional portal.
Now that you brought it up, you gotta do it! That was me with the 4X Shooter rig.
That reminds me, I have some photos to post in the Q8 thread…
I could only assemble a single GT dumbbell with the help of my friend’s GT. You can make a pair! :partying_face:
You can run two carriers back-to-back with an insulator between them and both heads will work. Ask me how I know.
+1, that would be interesting.
My hypothesis is that there will be some perceived difference between reflectors, and more than difference in measurements. At least very little between two examples with the same emitter when accounting for bin tolerance. There might even be very little difference between the two planned upgrades. We’ll see, I guess. The only way to really approximate the reflector quality tolerance would be to test lots of reflectors in one light, which can be a laborious task.
I’m kind of glad I have not received mine yet. Reading about these experiments going on (while stuck at work and in the city with all the light pollution) is more interesting and less frustrating when I don’t have a BLF GT staring at me on the table. :innocent:
I too saw greatly reduced lux numbers in my normal 5M tests. I set up and did a 15M test and got 1.2375Mcd. But that figures out to 1.38Miles and then I did the beam shots that showed light hitting the water tower at 1.9 miles.
I have a couple of friends coming over this weekend for an emitter swap party, we’ll probably do a 50M test on all our GT’s after the swap. They ordered D4 emitters at 5700K from Richard, I found some E4 5700K at Arrow in HD trim, have them on the way and will try slicing the dome off and chemical de-dome, see which works better. The Cree datasheet lists the HD D4 at 550 lumens at the 350mA test level, the E4 does 717 lumens at the same level. So I hope to get a clean slice and replicate the HI and see 2400-2500 lumens out the front in mine. A buddy told me that Coleman lantern fuel does very clean de-domes with little tint change, I aim to try that.
We will have 4 GT’s here this Saturday, should prove interesting.
Dale, I’m just curious if you’ve considered trying to de-dome an XHP35HD to compare?
The GT handle proto is finished. I’ll get some pictures posted up later this evening when I get home.
DHL called me today.
It seems I have pay a small fee but all is good now.
Here’s a quick teaser
Here’s a quick teaser
Looks good, very simple design but very functional. (I thought about an exact same handle design after you had said that it can be made ambidextrous)
Bo4ka:Tested throw with my luxmeter LX1330B.
Stock Thrunite TN42 CW at 4m gives me 700k lux. —-> so my luxmeter is definetly not underestimating!
8 fully charged 30Q
BLF GT at 4m 820k lux.
BLF GT at 9,5m 993k lux.
…far away from 1,3 million
Thought I remember seeing that minimum distance for measurement was 40 meters or at least something further than you used because beam convergence has not occurred at the shorter distance?
At 5 m i got 850000 at 10m i got 1,1150,000, at 15m i got 1,270,000.I,m gonna try and do 20m when i get the chance.
Sorry, I will be more specific. This is a list of people from the 3rd shipment who have either got tracking notices or received their light. These are all international orders and only DHL as far as I know.

Megabassie, Polarweis and me didn’t receive the GT. After a call with DHL they told us that they have no info about shipment to my address. So at this moment we don’t belong on the list...

I put my address down again because I want 2 sets.
hello
one question, with regular shipping does Neal provide a tracking number ?
thanks

don’t think so. Imo there were no registered mail shipments so far. Latest DHL shipments didn’t got a tracking code.

You need minimum 20m distance for a light with a reflector as large as the GT.
Is there any particular reason the waybill number of the DHL shipments aren’t being supplied to people? I see a lot of people not getting their tracking.
