An electrician I recently got a bid from made a number of recommendations involving installing what he called "Four-Oh" lights. I wasn't sure I was hearing him right, so had him spell it out. He told me there are great fixtures which are labelled "4/0" and that, with LED bulbs in them, they would work well for some of the lighting projects we discussed.
So, while out at the home improvement centers for other things, I took a peek in the light fixture aisle to see these 4/0 lights, but I did not see anything labeled that way. The Internet shows nothing, either. Has anyone else heard of these, or have I been sent on a snipe hunt?
