<strong>Yahoo Message Number: 75705</strong>Hi group,<br/><br/>I bought a bunch from 1000 bulbs made by Plusrite. Unfortunately, the combination of the heat and my charge voltage of 15 volts blew them out within a month or two. Given this, Plusrite recommended I check out the 24 volt bulbs and try them. This is actually where I was headed when I responded to Rosemary. Will get back to the group...
