Let there be light—if you have a USB port

 

by Craig Anderton

 

 

When I saw my first light powered by a USB-port, I was smitten. Whether trying to get work done on a plane without disturbing the grumpy person sitting next to me or running a live laptop set in a dark club, I had found the answer. Or more realistically, almost the answer...it used an incandescent bulb, drew much current, weighed a lot, and burned out at an early age. I guess it was sort of the Elvis Presley of laptop accessories.

 

 

Mighty Bright introduced a single-LED USB light a few years ago that fulfilled the same functions, but much more elegantly. And now, unlike Scotty in Star Trek they actually can give you more power—with their new 2-LED USB Light.

 

What You Need to Know

 

  • The two white LEDs are controlled by a push switch so you can light one or both LEDs.
  • Compared to the single LED version, having the extra LED available makes a big difference in terms of throwing more light on a subject.
  • The gooseneck is very flexible but holds it positions, and the weight is reasonable
  • The size is about the same as the single-LED version, and it fits in the average laptop bag without problems.

 

Limitations

 

My only concern is the weight—not because it weights a lot, but because USB ports aren’t exactly industrial-strength. However if you plug into a laptop’s side USB port and bend the light in a U so the top is over where the USB connector plugs into the port (Fig. 1), then it becomes balanced and places little weight on the port itself.

Conclusions

 

Once you have one of these things sitting around, you’ll find other uses. Given how many computers have USB ports on the back, plug this in and you’ll be able to see where all your mystery wires are routed. I take the 2-LED USB Light when I’m on the road, and combined with a general-purpose charger for USB devices, the combo makes a dandy night light—helpful in strange hotel rooms when the fire alarm goes off in the middle of the night, and you don’t want to trip on your way out the door. Also, lots of keyboards have USB ports and assuming it’s not occupied with a thumb drive or similar, the 2-LED USB Light can help illuminate the keyboard’s top panel.

 

Considering the low cost and long LED life (100,000 hours, which equals three hours a day for 90 years), I’d definitely recommend having one of these babies around. You never know when you’re going to need a quick light source, and these days, it’s not too hard to find a suitable USB connector to provide the power.

Awesome stuff those super brights are. I have a couple of non usb ones that have come in handy over the years. The usb should be even sweeter.
Mine are the clip on, kind so you can attach them just about anywhere, on a music stand, over your guitar pedal board, or mixer. They should make one that plus into a Pedal Power II. They might, but I have yet to see it. Maybe I should make one that plugs into a Pedal Power II and screws in to a Pedal Train.
