21134 Compact Fluorescent 2 Pin Single Tube 4100K, 13-watt

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.

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.

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

These bulbs will flicker and buzz for a second or two when first switched on. After that, they work fine. The original Panasonic bulbs that were replaced never did either of those things and have worked for over a decade.

this light bulb is not as bright as the one I had and it is shorter than the original so far I can not find the one but it is better than no light at all

Fit perfectly. Had the two plastic grooves on the edge I needed and was missing in the last one I tried ti buy (from someone else) plugged in and lights up! Can see in my backyard at night again.

Good product good price

Ordered the two pack, one had been previously opened and packed differently than the other. I installed both, and moments later, one begins to flicker.

It was the right one , not expensive .I will buy again.

This is a very yellow light. Its the first so called flourescent light I have seen that is yellow. I guess I`m stuck with it.
