Full spectrum lighting source - Waveformlighting

[Claudiusx]

So I spent a little time trying to find a company who actually tries to make full spectrum bulbs in the sense of what we want, mimicked spectra of the sun.

Think I found it.

Seems like red is really hard to get, but this one gets a lot more red than others, and is generally a much closer match to the sun than others.

What's Different With ABSOLUTE™?
Traditional white LEDs use 455 nanometer blue die as the underlying light source, and a dual-phosphor mix of green and red phosphors to achieve a semi-full spectrum light output.

This results in what is commonly referred to as the "cyan gap" - where there is a lack of light energy in the region between blue and green wavelengths, and an overshoot of blue wavelength energy. A close look at color rendering scores such as CRI R12 will also reveal that blue colors may appear over or under-saturated.

ABSOLUTE SERIES™ LEDs utilize a different method of producing white light to eliminate the cyan gap and blue overshoot. By shifting the underlying light source wavelength to a violet 420 nm die, a fuller, wider spectrum is made possible. This also provides energy coverage down to the nUV wavelength range.

Cool stuff. Except this is probably a separate topic so I'm going to start it's own thread on this so it's easier to find.

I will note that 99 CRI, or the CRI scale in general probably doesn't hold much merit in regards to what dragons perceive light as. But what is important is the spectra analysis, as it's the closest spectra output i've found so far to sunlight.

They also have other products on their site that come close too.

What's interesting is they also have options to buy just colored LEDs. You'd think a simple solution would be to just add a red LED array to your full spectrum light array to fill the missing 700- spectra.
But, even that only peaks at 630nm

They offer an IR LED also, but it's spectra is 840-870, with a peak at 850.

Sorry I'm excited by this company. Nerding out a little.

Seems like red is really hard to get

Do you think that's because it gets close to--or they're trying to avoid--the IR spectum?
(Yes, I read your comments about the separate IR bulb)

Any feel for how much these fancy bulbs are going to set us back?

 

[Claudiusx]

Yeah it probably is to do with that. I don't know for sure but that would be my guess too. Either that or it's just simply too difficult or to expensive to get the right phosphor or whatever they use to emit that wavelength.

Figured I'd poke this forum a little. The more and more I look, the 700-800 range is always lack luster to fill- makes me wonder what element the Sun has that we can't contain in our bulbs- at least for elementally composed bulbs compared to LEDs. LEDs are definitely capable of a lot, but they're, obviously, running into the same issue.

Something I noticed is that 700-800 probably isn't much of a concern for most companies since they're focused on making it look red instead of being 100% red- using blue as filler for increasing the brightness and what-not.

The elements I noticed was Oxygen and Nitrogen, at least elements in the Sun, that manages to fill in red a bit. Obviously there are other trace elements that most likely give off red too, such as Iron at certain isotopes.

I've got to say that Waveformlighting is absolutely doing a great job.

(Pfft- You've got me nerding out a little, but I'm looking at elements and gonna see what-kind of research I can find where people tried to produce 'redder' lights.) :lol:
