All you need is some rattle can, and 3 or 4 hours. When you done you'll have an outside light that you and your neighbors will love.
~Spray on glass etching $10
~Rust-Oleum Primer $5
~Rust-Oleum Flat Black Paint(or whatever you want for a finish) $5
~Bucket, Water, Car Wash Soap, Towels
~3 to 4 Hours
Step 1: Disassemble
This step is very straight forward assuming you have some mechanical skills. If you don't, reconsider committing to this project.
TURN OFF THE POWER and remove the light from its wall. break down the light as much as possible, and be sure not to lose any screws or nuts.
I had to use a shop vac to suck all the bugs and spider webs out of the lights.
Remove as much debris as possible to prepare for washing.
Step 2: Washing & Staging
I used a small amount of car wash in a bucket with some water and a wash cloth to scrub the parts.
After cleaning and drying, line the glass out on a drop cloth. Make sure you have the back side of the glass facing up; the back side faces into the light.
Next lay out your parts on a drop cloth to prepared for painting. You may have to prop them up so that you can paint all angles(use pictures for referencing).
Step 3: Painting
I found the spray-on etching at Michaels, it took 4 coats to get the coverage I wanted. Make sure you apply it evenly.
Paint the parts with primer first, it took 2 coats and some turning over to get full coverage.
I used flat black paint as the finish but you could use any color you want. Just make sure you get full coverage, and try not to cause any dripping. It took me 2 coats to achieve the right finish.
Make sure you allow 20 minutes of dry time between coats, and you might have to flip the parts over to get the hard to reach spots.
Step 4: Reassemble
Give the parts time to dry before reassemble them.
I waited a day before rebuilding the light. It all went back together without a hitch.
Make sure you install CFLs to save energy.
I had a few spots that needed touching up, so I sprayed some paint out in a bottle and used a model brush to paint it on.
again MAKE SURE the glass goes in with the spray-on etching facing inside.
Step 5: Enjoy!
Refinishing my lights instead of buying new ones saved me about $180, and saved the landfill about 20 pounds of trash.
I like the new defused glow the lights produce, versus the old bright directional light.
My lights look like they came from the streets of London now.
