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

The main difference was the original Narsil ramped to the maximum current output of the driver which was 2.5 amps at the LED. Prot Narsil used here ramps to 2 amps which is where this run time test was carried out. Double click takes you to 2.5 amps.
The surprise to me was the little difference there was running at 2.5 amps against 2 amps in light output and throw.

Pretty neat, 30Qs do not have the highest mAh and it is with four where eight can be used too in the production lights.
I can’t see the runtime graph in the sole BT31 review but the text say it keeps the output above 50% indicating a decreasing output over time.

I want a keychain ring!

+1. And how about a diffuser? :smiley:

Huge kudos to all the folks here that are designing and testing these BLF creations. It’s so cool to see BLF being used as the medium to make these lights happen. The GT is looking absolutely formidable. And I’m also seriously impressed by Steve’s shots where the Q8 beer can floody light holds its own against some serious throwers simply by virtue of its sheer output. Incredible! :+1:

Heheh yeah SB, agree!

Or a deep carry pocket clip :smiley:

wish u had a tn42 to compare it to

hard to believe it will out throw this
cant wait to get this in my hand!

Talking last changes
And a method of payment is agreed upon (for the PayPal users)
Each on the 555 first list gets a PM with Neal included.
Reply with email address
Lumintop will send invoice of $14 stating “BLF GT parts”
Pay within 5 days
no response to PM or payment made and we work our way further down the list

At a future moment a second invoice is send for $97 “flashlight parts” (or more if somebody wants cells)
no payment in five days, the $14 is given back minus the PayPal fees and we work our way down the list

People after the 555 get the same PM, and two invoices at a little later moment.

Based on actual payments LT knows exactly how many are needed for the groupbuy.

Do you know when can we expect this pm?

Not yet
Dang I had opened this topic to read not post info belonging in the main thread, will copy paste it later :wink:

For those that dont know I’m in The Millers bad books. :stuck_out_tongue:

Heheh aux contraire, mon ami :wink:

heheheh :smiley:

So, the GT comes before than Q8? :open_mouth:

Yay. I am on #548… 548 to 555 are mostly from the CPF. We are lucky.

Very true, that BT31 is quite expensive and under power. You could buy known brands with good reviews all over the internet.

That is really a good picture. Clear and crisp, shows center profile as well as spill. Nice.
