Let's say I would like to get a Convoy L2 smooth replacement reflector. The part is not for sale, which is weird because all other reflectors are (L6, M1, M2, M3, M21C, M26C, and so on). So, how do I order something like this? Custom order? How does it work?
It is not monochrome, it has a wide spectrum, because its light is phosphor converted from a deep blue base emitter. Almost all deep blue is gone, and what you get is slight green and a fair amount of red/deep red as well, besides the dominant wavelengths.
Thanks guys for quick jump in. I’m not good at reading specs, so your rescue was right in time.
But I should have studied the picture better.
Anyway, the diode is in my shopping cart already.
I’m thinking of an anti - fog flashlight but I’d like to ask what do you think.
Which one can get through the fog better, monochrome 590nm or “composed” with dominant 590nm? I also have XP-E2 with monochrome 590nm….
I think, both of them will be similarly effective regarding fog penetration, but with the converted one, you will be able to see a few different colors as well, so overall, a bit more information, better detail recognition.
Looking at the spec sheet, this tint is not as powerful as the “pure green” variant (which is also a phosphor converted wider spectrum one), also, it starts to lose output, when being warmed up, so about 1.5A to 2.5A would be the best current for it to be driven with.
What you comprehend as best thrower fog colour also can be explained by which colour is the easiest for the human eye to process. This also explains why car fog lights are yellow. They are not allowed to be red, green or blue, because of the traffic lights. And they don’t want all kinds of different fog light colours in the traffic like pink, cyan, violet, turquoise etc. Therefor the improvised standard for fog lights is yellow (3000K). So for a flashlight to be used as a fog light outside the traffic, red or green may still be the best, as these correspond to the red and green receptors in the eye.
Hmmm. Interesting approach. I own a couple of red lights. I’ll buy, test with the other colors and let you know… Wow, red foggy light reminds me horror movies.
2.5A would be also a sweet spot for yellow also, not only the red Osram. Just for the yellow, spec sheet shows around 2.8-3.3V forward voltage depending on current.
Can this driver output this voltage, or it is only meant for 2.0-2.5V, as seen for the red emitter?
