LED - 3W Aluminum PCB (5 Pack, Blue)

So much power and light from such a small package. This 5 pack of blue 3 Watt aluminum backed PCBs is sure to shed a lot of light on any project you add it to. These LEDs act as any other LED except these little guys require much more power while delivering a light as intense of a thousand suns going super nova (this is an exaggeration but you know what we mean)!

Each LED in the pack sits upon an aluminum backed PCB to help with heat dissipation and emits a deep blue light. Additionally, each LED requires a forward voltage of 3.2-3.8V at 750mA.

Note: We like to joke around about super novas and all, but seriously, don't look directly into the LED.

  • Forward Voltage: 3.2-3.8V
  • Forward Current: 750mA
  • Viewing angle: 125±5 Degrees
  • Luminous Intensity: 30-60LM
  • Wavelength: 460-470nm

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

3 Soldering

Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    There are nice and bright I'm going to put 3 in series off a FemtoBuck to identify a target to shoot at for hockey. Is there any connector that can be soldered on or just have to solder wire directly to the pads?

    I had a blast doing thing with the green luxeon rebel LEDs, how do these compare?

  • I had hard time soldering these. Any hints for the future? I found I had to apply a lot more flux than in the past. My temp was 750 F. I was using flux core solder about .032".

  • EvilTwin / about 10 years ago / 1

    Hey! wait a minute, if the Rebel LEDs were like five bucks just for the LED, and these are eight bucks for 5 LEDs and carrier boards, I'd really love to know how they compare?

  • ...I didn't really want my retinas anyway.
