Found eleven of these tubes in my usual
scavenging bin. I put them aside because of the HO mark and because I have a fondness for t5 tubes. As a bonus they are rare at 3000°K. I couldn't find any info here on LG and the tubes are costly on eBay, so I went back and "saved" them.
What will run these? They are longer than F54T5/HO/ tubes by 10 inches.
