I am building a SAD (Seasonal Affective Disorder) light box - its a super bright light.
The specs of the LEDs I am using:
50W Warm White LED IC High Power Outdoor Flood Light Lamp Bulb Beads Chip DIY Lighting color: warm white Color temperature: 3000K Beam angle: 120 degree Working voltage: DC 32-34V Working current: 1500mA Power: 50W Luminous flux: 3800LM Size: 52 x 46mm
Although these specs don't specify the maximum temperature they can handle prior to failure, what temperatures can LEDs typically withstand?
As a ball park figure I can tell you an Intel CPU is recommended to stay below 70°C but can handle upto 100°C at most - but I don't know what the thresholds for LEDs are!
I'm using a coolermaster i30 on a 150x150mm copper plate to cool 9 of these LEDs, the i30 is supposed to be able to "cool to 320Watts", which I would assume means it can keep a 320 Watt CPU below 70°C
