Yes, and thereâs more of them in the house, my son is particularly fond of cactuses. You just gave me an argument to sell the flashlight hobby to the family
i did the first steps with my BLF GTA (Giga Thrower aspheric) Aiming to kick the Optofires ass which uses a 120mm lens as well. The light already fires up, but is bad focussed at the moment. Quick and dirty put together for a first measurement. I measured 1.7 Mcd (8metres) already - without the Wavien Collar.
Been thinking of what kind of mods for this light and started to wonder what kind of IR LEDs are available these days that would work well with the GT.
Anyone else looked into this as of yet? If so, what kind of thought/research have you done? Any IR LEDs compatible with enough output to make it viable?
Kenji, out of curiosity, where did you find a lens of the right diameter and also with (about,I see cardboard bits) correct focal length? Or were you lucky?
I was lucky because this was the only suitable lens left by Enderman at Optolife He chose the A380 lens from optolife and i bought the only one left A037. Focal length 115mm which was almost perfect for the GT from the first drawings (reflector height 120mm). So i bought this last lens in stock some months ago.
Lower temperature = higher output, even if the LED is very low wattage
Thatâs why I used a CPU heatsink, cooling fan, and liquid metal, so that I could run my Black Flat up to 6A without a decrease in output.
Who knows, maybe they produced a few more.
When I bought mine from them a year ago it still said 0 stock on the website but when I contacted them they said they had some
Mine underperforming too. I even charged my 8 sanyo GA batteries to 4,23V to make a difference but I canât go above 981000 Cd. My reflector also not the best this yearâs batch.
Today I got a friendâs GT and I will measure it too if it make more candelas.
I also got an Opofire 120mm lens and with a dedomed XP-G2 I got 1,7 MCd with 1 cell at 4,5A.
What distance are you measuring it at? The humidity in the air, dust and a bunch of other things can have big effects on the readings with lights this powerful.
On my own GT depending on the day and distance I have gotten readings ranging from 800kcd up to 1.17Mcd, all with the exact same light.
I think the question was directed at ZozzV6, still here is how we measured our GTâs: in the hallway of Nicoâs cellar, at 13 meter and 23 meter (if I remember it well), the results did not differ much so I do not expect the throw to suddenly go up by much if measured further. The difference between Nicoâs GT and mine next to each other was clear and significant (1.16kcd vs 875kcd).
But Iâm a happy camper already, with your driver and XHP70.2 led I will have a fine modding project ahead
