I sent Zebrlight a message asking when I could Pre-order an H603. I'm really looking forward to this light!
"We'll announce the H603 in about 2 months."

Which means a long wait before release....

H603w? Just when I decided I wanted the c...Before ordering H602w I decided to ask Zebralight once again regarding expected H603c release date.
Their response was that the H603c/d and H603(w) announcement and start of pre-orders is expected in 2-3 days.
Pre-orders have started on their website

Pre-Ordered an H603c. Really looking forward to this one! Almost ordered a "w" too.....perhaps next week!

I just received a ZL 502pr, but I see no significant difference with 51r and 501r :-(
should the difference be easily seen? or is this only a subtle difference?

The r is 620-630nm and the pr is 650-670nm. There should be some difference but the question is, will YOUR eyes pick it up?
Some will notice and some won't. Plus if you r is around 630 and your pr around 650, there isn't much difference in nm.

If my eyes can't pick it up, what's the sense of boasting that it's "warmer/photo red"?
I feel like I've been manipulated into buying something that doesn't make any significant difference (But I'm still not convinced I did get such a "photo red" LED, I think the only way to find out is to measure the wavelength).
In fact, the H51r gives off "redder" light than the 502pr...

I assume for darkroom use where extra assurance the light won't affect your photo paper, or perhaps for astronomy where some may be using filters specific to that shade of red.
Short of having a spectrometer, I'm not sure how you might test to be certain what wavelengths each of your lights is producing. Sorry I can't help more.

Did you see this: https://github.com/axd1967/502pr/tree/master/grating
It gives an indication of spectra; seen the comparison with the SL red, which is really red, I think.those spectra speak for themselve.

Fact is that the ZebraLight H502pr is NOT "deep red"; in fact it is even less "red" than the other red LEDs. The grating setup gives a heavy indication that my eyes are right.
Communicating with ZL seems to indicate that ZL will not confirm my suspicion, and seems to blame the driver.

ZL appears to be overly guarded with communication to the public.
I once inquired of their H53c throw capability. All I got was a denial they had Intensity or throw figures and got a nebulous answer on range in its place.
Trying to calculate the throw myself, I asked if there had been any changes to the reflector/lens geometry. A simple yes or no would have sufficed. No would mean the geometry could be ignored in my calculation. Instead, I was met with and dealt with as if I were asking specific internal dimensions for the possible sake of stealing proprietary information, and denied the appropriate response to my question.
It's not rocket science, and no one will take over the world with flashlight technology. Good grief, if I wanted to steal internal reflector geometry I would have opened up the unit myself and measured it.
