The part number is CXA3070-0000-000N00Z230F. Here is the spec sheet. I would have preferred the CXA3590 but I have not found them available anywhere yet. They are both awesome though there was no sense waiting. Planning on running these at 720mA-740mA so they will dissipate about 25 watts each. Efficiency should be a minimum of 42%. Color temp is 2950K-3150K. 3500 lumens each or 139 lumens/watt. LER is ~328 (Thank you for that Mr Flux) I will test the vF while they are cool and after the heatsink has warmed up and stabilized to try and estimate the Tj. I will also check ambient and heatsink temps with infrared to try and get some idea of the total thermal resistance. These will be passively cooled just like the R/W/B modules with 105-110 sq cm /watt. After some testing I realized that the circulation fan was significantly reducing heatsink temp so that is a nice bonus. The hottest parts of the R/W/B heatsinks measure 25C with ambient at 21C so that is probably overkill. The sinks are 5453 sq cm each so I could probably run 55W and stay under Tj 50C even in the summer. I might make some reflectors for the COBs. Nothing fancy just flat white cones better than nothing.
