Sylvania 64490 in High Intensity Discharge Lamps

The lamp was well packaged and arrived in perfect condition. These lamps have at least 2 tips of different lengths. At first this didn't work in my lamp. After examining and purchasing a lightbulb at a local Lowe's store, I found that the grommets come in a variety of lengths. My mount required a longer tip. This bulb and the one sold by Lowe had no electrical contact. I solved the problem by soldering a large solder pad onto the tip to contact it. Now everything is in order. This bulb was $10 cheaper than Lowe's. I have not yet seen another model lamp with a longer tip. There was no model number on the blown bulb. That was enough for 6 years of regular use.

Pros
  • Operating within 15 degrees of vertical, this lamp may be operated in an open fixture provided the installation is clear of people or combustible or combustible materials, otherwise it must be in a suitable closed lamp are operated.
Cons
  • unreliable
