My double 55W retrofit kit from AH is on it's way as of today, in
....
canopy. I'll let you know how it works out for me if you like... I'm
planning on retrofitting an All-Glass deluxe hood (gutting the
single-bulb 48" light strip and putting the two 55W PCs in its place).
I plan to document it on my web page at some point.

Okay retrofit (and write-up) finished, if anybody is curious, check it out:
