10W quad wavelength UVA LEDs on copper PCB

These were custom made for us and have four 3W UV LEDs on the board, all wired in series. They have one each of 3W LEDs in 365nm, 375nm, 385nm and 395nm, so are effectively a wide band UVA LED.

LEDs are mounted on a copper PCB and rated current is 700mA, Vf is 12-15V.

Note that because there are four different LEDs, they may look slightly different.
