Using Inexpensive DJ LED Lights to Jazz Up Video Productions
Looking beyond the small set of white and bi-color LEDs specifically made for video production, you can find a whole other world of LED fixtures made for other markets--including "disc jockey" LED lights and controllers. For the cost of one good fresnel light, you can have a multi-light, expandable LED lighting package.
Final Thoughts
The LED heads are small, light, and cool to the touch, so it was no problem to move them around and redirect them as needed. The beam angle is about 40 degrees, and it is not adjustable. You can diffuse it with some gel in front, but these lights do not have slots to hold scrims, gels, or doors to clip a gel to. However, since they run very cool, it's easy to simply tape what I need directly to the fixture.
If you plan on using these lights on light stands, they come with a yoke, but typically have options only for a floor stand or a clamp to hang on small-diameter pipe. You can find any number of light stand to yoke adapters at various online shops.
In the end, I was very happy with the LED lights. They did what I wanted them to do. They worked as I wanted them to work. They provided a "value added" service for me to offer the client and they solved a specific client problem. That made the client happy and that's a good thing. My controller will handle more lights than just these four, so I plan on adding more and different fixtures to my arsenal over time. I found them to be an affordable and worthwhile investment for the future.
