Review: I can see clearly now! - My desk lamp is back working. Bright white is way better than the soft white I use to have. High quality at a great price.
Review: Tip: Re-size the picture on your phone or tablet to determine the size you need. - I knew I needed a 13 watt tube because it was clearly stated on the base of the tube I was replacing. But I know from past experience that isn't always the case. So I confirmed this was the right tube by viewing and resizing the picture on a tablet until it matched up to the tube that was being replaced. Here are the measurements as close as I can tell: The length of the two u-shaped tubes is 2 15/16" from the ceramic base to the top of the tube. The rounded square, ceramic base measures 1 5/16" across by about 3/4" deep (including the smaller portion of the base to which the prongs are attached). The brass prongs are 1/4" long, and the plastic, pronged fitting at the bottom is 7/8" long by about 1/2" wide. This tube replaced a Sylvania Dulux D 13W CF13DD/827 that had itself probably been a replacement tube. It was purchased for a solitary recessed fixture in our kitchen. (We also have five bright, recessed LEDs when we need lots of light, and a 14" Solatube with nightlight that provides sufficient daylight, and a small amount of night light when properly charged by the sun). The tube I purchased is a 3000k because I don't need a lot of light from that fixture. If you need more light then you might want to go higher. The new tube fit into the fixture quite firmly with a only a small amount of persuasion. It flickers for a brief second when turned on, then stays on and provides enough light for a quick visit to the kitchen when the night light is too dim and the five LEDs are too much. It makes a fine replacement for the previous tube.

### ⭐⭐⭐⭐⭐ Very cool and a lot easier than shopping locally
*by N***M on October 25, 2025*

Works exactly as advertised. Very convenient to buy from Amazon rather than from a local plumbing and electrical store and cheaper than them too… I checked
