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

Yep, that’s why it is important to compensate for all sorts of surfaces and sheets the light has to travel through/reflect off when measuring light sources in a sphere for example. With a spectrometer that’s easy with an incandescent light source. Just measure the source in free air directly first, then in the sphere, normalize the SPD and create an absorption correction for every wavelength.

For people using the Argyll spotread this is now easier than ever, since I managed to get the developer to implement the compensation in real time with the -E flag using an absorption file. Before I did that manually in Excel.

Because my sphere measurements are all manual, and with a luxmeter instead of a spectrometer, I can’t do the correction on the spectrum unfortunately. For cool white light my most used sphere causes a CCT lowering of about 600K, that probably makes my readings off by a few percent for cool and warm leds.

I agree. I do like the style of the original font better. The “B” is just fat around the two curves. It doesnt match the weight of the other letters and makes the left side logo look heavier than it already is.

Either way. When I’m using it and showing it off to everyone, I doubt any of this will be a factor.

As it was said in the BLF GT thread :

Here is a quick test with the Ubuntu Bold Font. (I didn’t verify the copyright (for commercial use, etc)).

Same with the battery tube a tad slimmer :

Pretty sure that the font can be even more “bolderized” in an another application than Gimp.

Here is a subjective selection of fonts (I didn’t check all the fonts listed)
Change the text and its size to have a better idea :

Quick test with one from the list (with slimmer battery tube) :

Please add me to the list. Thanks. And thanks for doing this. Good recognition of the need for one of these.

I’m very interested. Put me down for two please!

Please add me to the interest list.

Thank you

Two please. Orsm work.

Please add me to the list for 1 lantern. Thanks!

Please put me down for 1.

Spoiler: I don't really know how to phrase it correctly and I do not say that to cross someone. But, regarding the font question, I cannot prevent myself to feel the result as misfit. All the BLF collaboratively designed products are well thought, and I feel like the font selection is not up to the task : representing the engineering challenge overcame.

Is the Ubuntu Bold really settled, or is debate still opened?

I didn’t know the original font was an option, it’s the cleanest look. Still, I’m down to see more font suggestions.

Can’t we use the same font as the BLF GT (+ GT70, GTmini, GTmicro) and BLF Q8 in order to create a consistency between all BLF creations?

Interested

Interested, put me down for one. Thanks

I prefer the rounded font of the BLF Q8 (there are 2 font for the BLF GT and are different) and went throught a lot of messages to find its name without result. I tried to find an equivalent but none were as well “balanced” (don’t know if it’s the appropriate word).

I prefer the Ethnocentric Font i posted above earlier over the Unumtu one. The Ubuntu font looks to “cheap” or plain, almost like an enhanced dot-matrix printer font.

I agree with DBSAR on Ubuntu.

Plus, Here is my overall preference in order:
Q8 style
Original/old font with the fat B fixed.
ethnocentric

Do not like Ubuntu or the rounded style of the quick test one.

For what its worth, I strongly agree. Ubuntu looks extremely plain to me, the Ethnocentric at least has character.

At the same time, and recognizing that in this post I’m contributing to this as well, does it seem to anyone else that we’ve spent an inordinate amount of posts on the *font *of the lantern? I guess its a sign that people are excited about this project such that they want to discuss it even when there’s nothing substantive to talk about, but still…

Please put me in for one lantern!
