I had a mini-heart attack until I realised my ceiling mounted LED light has indeed two faces and is visible towards two directions (30 m), because the data sheet indicated a connected load of around 8 W!
So my interperatation is the Watt per face is 8 / 2 = 4 W and is okay.

Sounds right to me.
Also sounds like you might want to seek a new profession if 3 W gives you a mini-heart attack! :-)
