Well now I'm a bit confused. This is the first I've heard of the ultra/ultra vs..... After a bit of poking around, I see these appear to be in reference to the iceLED line. I'm wanting to go passive so I was looking at the 9980 line not the iceLED ones. I didn't notice before but I see in John MacDonald there in the last page mentioned using the non-Xtra ones in his build, unless he just left the Xtra part of of his description on the reply.ultra = citi clu048, 058
xtra ultra =vero 29, cxb 18xx/25xx/30xx
ultra vs = cxb 18xx.25xx.30xx
Looking at the datasheet info, is "Dissipated Power Pd" how much watt-heat it can dissapate (48.9 W)? The COBS will be running high 30s with the 1050mA I'm pushing thru them. Please let me know if I'm interpreting the data wrong?
thanks
Morv.
