I want to make a sunrise alarm clock, and am wondering whether the 'Super Bright 5mm LEDs' would be bright enough to illuminate a dark room. I am also wondering about the LED backlights.
If anyone has any experience with these, and could tell me how bright they are relative to a dark room, I'm be really appreciative.

edit: I realize that I'd probably need an array of either option, but am still wondering on the relative brightness.
Want to make a sunrise alarm-clock... How bright are these L

These are bright as 5mm LEDs go. And about 5x more efficient than an equivalent incandescent. But they are pretty small and the total light output is about that of a candle. You would need a total of about 12 watts of LED power to match the total light output of a 60 Watt lightbulb.
Each one of these runs at about 3.2v @ 20mA or 0.064 watts each. A 14x14 array of these would be about 12.5 Watts.

You should check this 1W LED, https://www.adafruit.com/products/518.
There are some 3W LEDs here, https://www.sparkfun.com/products/13104, https://www.sparkfun.com/products/13105.
