anyone know what size of passive heatsink is ballpark necessary to run 3 x 10W LEDs? i bought pic related. haven't cemented the LEDs do it yet but i have a feeling it's nowhere near adequate. i only need to keep the LEDs cool for about 15 minutes since they are for intermittent use (365 nm LEDs for PCB photoresist.) the LEDs have a metal base ~20mm x 20mm each.
