Picture of Polychrome LED Filament Lamp

I found these clear, filament style, LED bulbs at a hardware store on Castro Street in San Francisco! The bulbs themselves are great and I wanted to make a simple light fixture to show off the whole rainbow.

For this project I used S4S hardwood lumber that you can buy from any big box hardware store such as Home Depot. I decided to use solid walnut for this project. I love the mid century vibe walnut brings and also the rich depth of color this beautiful hardwood takes on after applying a finishing. That said, you can use any hardwood you perfer. (I'd love to make this again with Zebrawood!)

This was a fun Instructable to look through. Very well done with the sharp photos, clear directions, parts list, and I especially enjoyed the 'lessons learnt' portions. While I don't plan to make this, I learned about available parts and techniques for my own future projects. Thank you!

Very pretty! I like colored lights that aren't Christmas lights, then I can have them all year long. I voted for you!

The wood looks gorgeous! Love the warm color and the strong grain. The bulb colors are really rich too and not 'washed' out. Nice job

Thank you! : ) I love those bulbs for that exact reason.

Very cool! I like the cast color spectrum of light as well, that's a great effect - unintentional or not! : )

Cheers man! : ) It's a very cool effect.The separation of the color casts get even stronger the lower you dim the lamp. Its been fun playing around with the different effects you can create with varying placements and brightnesses etc..
