Review on 💡 Brillihood Equivalent Fluorescent Fixtures Dual Ended: Enhancing Lighting Efficiency by Ryan Eppinger

So *assume* the 6ft fluorescent tubes are the same length; I upgraded my old ballasts with HO LED tubes - the tombstones had to be replaced as my new LED tubes were two pin HO types. Replacement was *simple*: remove sheet metal end caps, slide out old ones, plug in and plug straight in (by removing the ballast, on my lamps - much more efficient!). All is well. The new bulbs just don't fit! Comparing the old single pin tombstones to the new HO's I lost about 3/4 inch in length and they didn't compress enough. I got creative with the tin snips and was able to quickly (once out) modify the metal "backing plate" on either end to keep those tombstones further away. I still don't know if single pin tubes are actually shorter than double pin tubes, if the LED bulbs were just made to the wrong specs, or if these tombstones were a bit longer than the old ones (es were very old lights from 1989). or so). Regardless, it worked out in the end and they seem solid, it was just a pain cutting and bending the metal to fit the bulbs between them!
