Based on the manufacturer supplied data, the Luxeon ES deep red EX6 bin is 38.5% efficient (700mA 50c). The Oslon Hyper red 3T bin is 41% (700mA). The Oslon Hyper red 4T bin is 46% (not yet available for sale AFAIK).
The Oslon 630nm JU red is 32% (700mA 50c). The Cree XPe 630 red is 42.2% (700ma 50c). It would be hard to get the Oslon to run at 50c and its output falls dramatically as junction temps rises.
The Luxeon deep blue MR3 bin is 55% efficient (700mA 50c). The Cree XTe deep blue Q04 bin is 50.5% (700mA 50c). I use both to widen the curve.
The numbers above are based on the minimum estimates. In practice the output will be slightly higher.
I agree with you the Oslon Hyper red is now the best deep red. There are 3Ts mounted and unmounted for sale from ideal-spectrum-led and they will ship to US. I believe Newark also has some available.
Regarding your measurements of the Luxeon deep red and deep blue from Steve's LEDs, what are you measuring your vF and mA with? Accurate meters and leads can be spendy (Fluke) and as the driver and heatsink warm up the measurements will change significantly. Some of my drivers put out 720mA once warmed up and some put out 680mA (cheapo drivers).
