Sfiligoi Astra - Nano LED

Not sure what Cree "certified" means.

Anyhow, so at 139 lumens per watt they are probably actually driving them at 350mA or about 1 watt power. This makes sense because they could not run these at 2 to 3 watts in that housing without overheating. X-PGs at 3 watts would need at least a decent heatsink and preferabaly some airflow too.
