Anyone know the max current ratings for the ultra-bright LEDS included in the starter kit? And for the red LEDs? Also, anyone have any specs on the CdS photocell?

Anyone know the max current ratings for the ultra-bright LEDS included in the starter kit?

green - 3.5v, 20ma
red - 2.0v, 20ma
blue - 3.7v, 20ma

And for the red LEDs?

2.5v, 20ma

Also, anyone have any specs on the CdS photocell?

Cell Resistance (Min) @ Dark 300 kOhms @ 10 seconds
Cell Resistance @ Illuminance 8 ~ 16 kOhms @ 10 lux
Rise Time (Typ) 55ms
Fall Time (Typ) 25ms
Wavelength 520nm
