4Sevens does list the bin and tint code on his
CPF Custom page. The WM-F3 in particular is in the GM102 kit category.
AVNET, which apart from the
high shipping costs to Europe and the no availability of stock, is selling these GM102's for $40. So if AVNET wants $118 total after shipping, that makes 4Sevens a great deal at $25.76 after his discount for the same thing!
OK, the WM bin is one notch below the highest available bin with 850-1000 lumens @ 3.2 amps. Probably why he's offering them at such a great price. That's still 2,014-2,370 emitter lumens @ 9 amps. In case you're wondering it's just a pixel ratio estimate of 237% increase @ 9 amps from the
Luminus graph "Relative Output Flux vs. Forward Current" on page 9 of their SST-90-W Data Sheet. The F3 tint has the BBL pass right through the middle of it, so this is an excellent color tint. The "SST-90-W Data sheet" lists the bin codes, tint codes and output graphs while the "PhlatLight Binning and Labeling" shows what the kit numbers mean. Member
DFiorentino's thread has recently been upgraded to include the Luminus color graph.
