Q: "I bought three replacement bulbs for Eclipse computer lamps and none of the bulbs fit."
Answer: These are exact replacement bulbs for your computer lamps. Over the years we have learned a few "tricks" to installing thes replacement bulbs. If you always leave your light on, the bulbs last for years.
The bulbs we sell are special Sylvania bulbs with a blue tint which is better for illuminating computer screens.
To Replace a Bulb in an Eclipse Computer Light:
Place the bulb on a counter, writing side up. Ignore the metal clamp on the right side of the computer lamp. Instead insert the bulb at a slight downward angle with some force into the left slot until you feel it pop in. We found that it had to be pushed in 1/16 inch to 1/8 inch more than we thought. Then push the bulb downward into the right clamp.
We hope this solves your problem.
Sincerely,
Barbara
