Have an old (1989) swivel/extended arm desk lamp used on sewing table and desk with bulb that burned out. Unable to find match to bulb's manufacturer's numbers until I found your website with picture and then great customer service where the original numbers matched those on this one. It works, as Tony Tiger says, greeeaat.

This is the second or third time we ordered this product for our 54 Unit Condominium that has 24 fixtures that require this product.

It is the most functional and reliable light in the many light products that are required for the external light requirements.
