【convoy】H4 and B35AM options are updated

Thanks

Just look it up in the specs document:

See page 8 and there you go.

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 just noticed Simon added S2+ body colors we haven’t seen before, deser tan, green, cyan...

Maaaan, one of the few good things in this crapy year is Convoy store for sure.

Well done Simon!

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.

Thanks, useful hints. I’m planning a small backup light, so amperage is fine. :beer:

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.

Hm? I had my green S2+ for years, and got hosts and shorty-tubes in cyan (and orange and purple).

Different shades, maybe?

(I’ve been trying to avoid AX for a while…)

I thought same thing. Have seen cyan, blue, green , purple before. Maybe not desert though

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.

Hello Simon,

I saw this driver, and I wonder, if it could be usable with the Osram KY CSLNM1.FY yellow LED: https://www.aliexpress.com/item/1005001619557257.html

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?

If suitable, could you please add red and yellow emitter choice for Convoy C8+?

Where do you see the NEW S2) colors? Do they still “lego” with OLDER S2 or they have the “NEW threads”

The desert tan version was huge back in the day

Good range of new emitters. Hope the warm LH351Ds end up in stock lights soon.

Maybe it’s only me. Haven’t seen those options before

The 3500k looks really interesting, if I read the BIN correctly it looks like a good colour.

Also do I understand from the datasheet it doesn’t like more than 3v which may be the delay as it requires a step down driver or something?

The voltage of the yellow light monochromatic light chip is the same as the red light, but this yellow light is a mixed light of blue and yellow light, not pure yellow light. The chip it uses is still a blue light chip, so the voltage is still 3.0-3.6V

Will the KY CSLNM1.FY be available in a S2+ ? I assume it will be with a 3175x driver due to the max 3A handling of the LED?

The highlighted color bin on your pic is U2, but the bin offered by Convoy is U6. getting those –0.0030 –0.0060 Duv bins (like U2) would be amazing but it’s possible they don’t even exist.

As for driving those LEDs, no difference with other 90CRI LH351D, max rating of 3A but can be driven without issue to 5A, linear drivers adjust voltage ( which is higher than 3V above 1.2~1.4A ) to get the desired current.

I see no reason for such driver not to be able to output regulated voltage and current (almost) up to battery voltage, as any other buck drivers. These are built the same way, only the inductor may be tuned to handle slightly more voltage difference (higher Vin to Vout with higher inductance value). So, I am fairly sure that such driver can be used with a higher voltage emitter.

Report here if you try.
