*BLF LT1 Lantern Project) (updated Nov,17,2020)

Please add me to the list for one, thanks!

Edit: and all accessories except batteries.

How i tested it was using both my lux meter, and the light meter app on my phone. i did measurements at 1 foot & 4 feet with the globe/shade removed completely & LEDs in line of-sight of the meter sensors, then did the same with globe in place. Will do that too in comparison to the V1 & V2 design prototypes to compare it to the production prototype. ( I also have my Lux/Lumens sphere , “Lumens Sputnik” .

The lumen sphere will give the numbers for comparison, if you manage to place the lantern inside, or at least stick the entire cup inside.

Measuring lux from distances will be too sensitive for brightness variations across the beam so it is not representative of total output.

Test for logo and exo2 black font on an existing picture :

Very interested

@Tally-Ho More pics please! Looks good so far, also a brief (or lengthy ) write up is always welcome.

How have I not seen this before.

Put me down for one please :slight_smile:

That is certainly another good idea. The other way to tell where the edge is to put the light on turbo/max this way we know that the other channel would not be discarded in the averaging. Blinking is welcomed

Interested, please add me to the list.

Sorry for the confusion, I don’t have a prototype on hand, just a picture from this message to test how the logo with exo2 font would look on it.
(Previous message edited).

I am interested in 1 please.

Put me down for 1!

Interested in 1 as well please.

the entire lantern will fit inside the sphere.

Looks good :+1:

Sorry to nitpick on the method: it helps integration quite a lot if you wrap as much as possible of the black parts of the lantern in alu-foil (but in a neat way using some cellotape so that the foil does not move too much across the measurements)

Please add me to the list for one.
Thanks.

Its trickier for measuring 360-degree lanterns versus directional flashlights no doubt, but will be comparing it tot its self with globe/shade on versus off, as compared to the V1 & V2 tests i done.

I think he means not relative numbers, but absolute numbers for the manufacturer?
