They're available in the US now.., at least in the 55W version. I just got some (Osram/Sylvania Dulux L 5400K 55W PC's - 2G11 style pins). The same ones that were listed in the table in Ivo Busco's article on Aqua Botanic... Total PUR 36.3 uE/s, PAR 72.2 uE/s.
The Duluxs replaced some 5300K's that I got from AHSupply. They're about $3 a bulb cheaper than the ones from AHSupply. I could tell within 30 minutes of swapping them out that they significantly increased the plants' pearling. Part of that may be that they are new bulbs, of course. The ones I replaced had about 3000 hours on them.
Take care...
Tim
