I tied with an OTT-Lite for more than 8 years, never replaced the bulb. I needed something easier to transport about 4 years so I could take it to tying expos. I settled on a Daylight brand lamp with magnifyer. The original OTT-lite is till going strong and is being used as a home tying lite for VEE with her Wasatch J-Vise. The Daylight lamp uses a similar bulb as the OTT and is still going strong. What I really like about both lamps is a lack of heat (yup, I had a Girrafe light and burned myself too), the almost shadowless light is really nice too.
