USHIO SM-8018 /6V-15W Incandescent Lamp
- Product Review (submitted on April 15, 2014):
This is a good bulb at a very good price. These bulbs generally don't last very long due to the heat inside the stand. I don't know what the rated hours are but I don't get more than about 30 to 50 hours out of a bulb, much less if it overheats due to filters on the field diaphragm on the base.
As a result I usually buy several of these bulbs at a time.
