I'm planning on having a set of blue LEDs connected in series. I'm looking at having about 30-40 LEDs in series. The power supply will be from a USB 2.0 port mounted on my television. Reading up on the specs for USB 2.0 it has a pin for 5v and ground.
If I used this as my power supply, will my LEDs light up as much as they should or would they be really dim.
The specs for the LEDs are:
- Material : Semiconductor; Light Color: Blue
- Head Dia.: 5mm / 0.197"; Forward Voltage: 3.2-3.4V
- Luminous Intensity: 2000-3000MCD; Wave Length: 460-463
- Size: 24 x 3mm / 0.9" x 0.1"(L*W); Package Content: 50 x Light Emitting Diode
