craig-IL sounds like Craig from Illumination Supply. He was on the forum for a couple of years but never did anything remotely questionable at least back then.
Hey guys. I am a big fan of the clip-on āglare guardā attachment of the Streamlight Super Siege.
I find it a brilliant idea: simple, yet useful, especially when using the lantern as a work light. And it is supposed to be quite inexpensive to manufacture, it is just a piece of plastic, after all.
I think it would be awesome if something similar would be available for the BLF LT1, either as an optional or standard accessory. What do you think?
It would be interesting to know how the diffuser wil influence the light in matters of cri and color temp. The one I use makes my lights look cooler.
I know it wonāt be possible for this one but, somebody spoke of remote phosphor domes. Wich I believe would be perfect for a lantern. I have looked into them but they seem not available anymore. I know yuyileds (?) uses them cause I broke one of their bulbs. The bulbs are really nice but could be a litter warmer for my taste for some applications.
A diffuser will blend the beam, even if the tint is all over the place from 4000k in the spot all the way to 6500k+ on the edges, which means tint shift goes away. However, that means the beam is blended, meaning that 4000k spot/6500k edge will now become a 5300k tint, which makes the light seems much cooler than it actually is.
Samsungās LH351D 90CRI 3000l-4000k-5000k have been tested to have very little tint shift, so that should not be a problem at all.
The LEDs themselves have little tint shift in the beam for the 90CRI versions, so normal silicone diffuser should work without any problems, if itās made consistently of course.
Thanks for asking that question though!
Does anybody know a source for good high quality diffusers?
Yeah, thatās way beyond what we can do in this project. Thatās the sort of thing LED manufacturers experiment with for household light bulbs, not something we can reliably get produced for a lantern.
Itās not even used much by LED manufacturers though. Philips did it for a while with their L-Prize bulb, but it didnāt stick around long. It was expensive, and people didnāt like how it looked.
The main counter-example Iām aware of is a lightsaber blade called a photon blade. It shines a royal blue emitter into a phosphor-coated tube to produce a bright green light. But itās nowhere near white, and the blade alone (without emitters or a host or driver) costs more than the lanternās estimated price.
Those are some funky looking light bulbs. I canāt find any of those remote phosphor domes, I did find a store where they where out of stock and they not really budget friendly.
But Iād check if white works OK, so it reflects some light back to the head for increased efficiency. Could be a worse blocker like that, so maybe itās not a good idea.
