Question About LEDs?

the power supply says 500mA

so should i just run them at 4.5 volts or can i safely increase it?

im gonna use this to light my fluval edge, and i'd like to get as much light as i can without causing it to overheat

I wouldn't run them at a higher voltage.
Unless you have the rating for each led i would stick with the manufacturers drive rating.
Maybe with a 25% more juice

If you are going to over drive them check for temperature.
those led made to simply die as in short-out not explode on fire.

good to know... been running them at 6 volts for about an hour.... the power adapter is hotter than the lights themselves. so far so good might try to go up to 7.5 volts and then will probably stop there
