5630s actually, They're roughly twice the lumens of 5050s. 5050s
5050 LED | 5.0 mm x 5.0 mm | 25 mm² | 16-22 lumens | 60 mA @ 2.8-3.4 Volts |
5630 LED | 5.6 mm x 3.0 mm | 16.8 mm² | 45-50 lumens | 150 mA @ 2.8-3.4 Volts |
And the strips were 300 leds per 5 meters, that's basically the standard. Compared to Swampfinz link for example with 5050s and 300 leds per 5 meters, should be roughly twice the output.
Just checked, it's drawing 156 watts at 12.5v If they were all running perfectly according to specs that would put them at something like 14,000 lumens.
After a couple years of wear and heat I'd be surprised if they're at half that though.
There are some interesting COBs out now that look like they'd be interesting to try:
