Hey guys, i wad plannin on a diy led build using 1w leds. Well i saw online and 1w leds come with 300ma and 350ma both... the drivers for 1w are all 300ma... im confused... would the 300ma work for 350ma? What is the difference between the 2??

Power is Current * Voltage. Current is always a maximum, so you can always run at less than the rated current.

So will the brightness/intensity decrease???

its recommended to run leds at 70-80% to increase his life utility

Hey guys 1 more question. Can u add 1w and 3w leds together and make them work on 1w driver? Anyways i want 1w output...

Yup! As long as your driver can output enough voltage for all the LEDs in series.

Well its a 24-36 1w 300ma driver. So 30 1w and 5 3w led will work?

Depends on the fV of the LEDs and the actual voltage output capabilities of the driver!

If that driver is a constant 300mA as it sort of suggests, to get to 36W it would need to be able to put out over 100V! Those figures don't add up!

Kool, so its better i only use 1w leds for this driver
