So I finally got my hands on some single crystal YAG:Ce phosphors!
Not cheap, over $300 because the minimum order quantity was 5, and they are only 3mm x 3mm.
They had some 5mm x 5mm ones too but that would have cost me over twice as much, although those would have been easier to work with.
Next items on my purchase list:
-blue laser driver
-blue laser lens
-blue laser protection goggles
It will be a while before I can test out the performance of the phosphors but I’m really excited anyway
All I know is that Saablaster claimed to be able to swap phosphor from SST-40 to XHP35. As well as to lift the die off the XHP35 package and put it on a diamond heatsink. Osram LEDs are different, but maybe he would be capable of doing a similar surgery to them as well.
Would he be willing to help you with that? I have no idea.
This light , the BFF, will beat them all. We don’t really need a measurement to know that. He is using a special bulb with an extremely high luminance that I never knew existed before.
A conservative estimation puts the throw at around 250Mcd.
Well I only have very rough theoretical numbers which are probably not anywhere close to real performance, but I have high hopes.
Once I order the laser and start doing intensity test of the phosphor crystal then I will have a better idea.
