bluest 20k DE hqi bulb?

[robster]

Based on Sanjay Joshi's bulb analysis it appears as if the EVC, Helios, and Sun Aquatics 20k bulbs are all the same bulb looking at the graphs. I am running the EVC 250W 20k and it is by far the bluest bulb I have ever seen. I also like the bluest bulb money can buy. I will probably try Helios next just to compare and since the graphs look almost identical.

I can't seem to find the DE Helios bulbs anywhere. Who sells them?
