Hi all, I noticed I was getting referers from this thread and also looked at the Megaman-PDF where I saw a spectral distribution, lumens and wattage - which is all that is needed to calculate the PUR-efficiency for the bulb. I've updated my list with two of the bulbs in the PDF.

I'm a swede so I have no clue to what you are talking about here though. I hope I didn't violate any rules of the forum by writing in english.

The wierd thing about the Megaman spectral distribution is that it looks like a tampered Osram-spectrum for their GroLux-bulb - and they have managed to mark the frequencies all wrong in the distribution too.

The red peak is from the phosphor 3.5MgO,0.5MgF2,GeO2:Mn which emits light at 658 nm. The blue peak is mercury at 436.6 nm. I used these references to cut out the spectral distrubition at 400-700 nm.

I've made a little image-analyzer in Java which iterates through the spectral distribution and calculates it's PAR and PUR. The process is described here:
