Help needed in identifying this 5050 mm 1W emitter

[CuriousOne]

Hello.
I got a roll of these. There is no datasheet, except the info written on the roll. Manufacturer unknown.
Light quality is really good, so I'd like to put them in use, but unsure of current. Seller says - 350mA
Maybe anyone can ID them, based on outline and soldering pad shape?

Regret that I can't give an ID on the part, hopefully someone else will.

What's the package marking BR5050...in the middle image, anything useful or just the seller's part number? Binning info might be a clue.
