Yep thats the oneI believe so. I didn't add the HT designation to the .pdf, but attached is the data sheet I was using.
cheers

Will they be in CRI 90,or just CRI 80?Did you do this on the new Nichia HT chip?

first samples just arrived, 224LPW and our SSK-272 will use these with G bin Cree Photo Red, we expect sys eff at 3μmol/J at least

Using the datasheets for LM301H (70-80-90 & ONE) and using the following values for the electrical input:So which one is it? 68% or 80%?
Well I've since remebered lol Dammit! The discrepancy is due to 1 metric describing the power input vs the energy emitted after the phosphor losses, and the other metric is describing the power input vs the energy before the phosphor losses.
When I assume a CE of 1, I get ~3.3μmols/J. The stated claim is 3.03μmol/J, so I'm assuming the CE for the phosphor film they are using is not 1 but something close to 0.918. I'm going to wrestle a little more with this.
I use this one:Do you guys know what luminosity function they use to build the data sheet? I've been calculating based off of the 2005 modification (Sharpe, Stockman, Jagla & Jägle -- tiny dots), should I be basing off of the 1931 CIE (solid line)?
