Sylvania 20318 Compact Fluorescent 4 Pin Single Tube 4100K, 13-watt: Efficient Lighting Solution for Any Space Review

Notice the small plastic latch on the base. My old Panasonic lamp has the tongue offset to the side, the new Sylvania has this plastic tongue in the middle.

I ordered this bulb for my Ott Lamp that I use for sewing. This is my favorite lamp given to me by my sister and I use it when I sew or embroider. I look forward to using this for many years to come.

excellent bulb. Can't comment on durability yet as I just installed it. But it is bright and white as it should be. Installation was a bit of a hassle, but it's NOT the bulb's fault, just a dodgy DeWalt build. I can highly recommend it so far.

This bulb is slightly shorter than the original bulb so it does not fit perfectly with the back in the light which prevents it from moving. I just have to be careful with the light. It wasn't easy to find so I'm glad I found it and it works, otherwise the light would be useless.

The bulb fits the 18V DeWalt DC527 light exactly, I removed the old bulb and fitted the new one with no problems. This lamp costs about 1/3 the cost of a boxed DeWalt lamp which means I buy another one as a replacement.

Can't find these bulbs locally, figured I'd have to replace the whole fixture when my old bulb died. This bulb was cheap and fitted directly into the lamp. The one I got was a warm white and I wanted a cool white but that's my fault, they included the color temperature in the title.

Assembly was so quick and easy a 5 year old could do it. Took about 5 minutes with easy instructions and looks beautiful! I wanted a glass side table for a couple of books and space for a cup of coffee. I have a metal table lamp next to my chair and this glass and metal table is a great companion. Love the shelving for easy storage and the overall look of this item - I'm very glad I bought it and the price was extremely reasonable.

Sylvania 13W 4-pin socket [2 CFL tubes] and Sylvania 26W 4-pin socket [3 CFL tubes] look the same === = NO . There are 2 button tabs arranged differently [see fig. red and green markings in the photo]. Simply cut the 13W key tabs to fit the bulb into the base of the 26W fixture. 13w key tabs [picture above left] cut/sanded/sawed. Can we just screw bases back together? I noticed that AMZ have 4 pin adapters to convert them to screw round CFLs.

With 1 necessary and 1 additional modification, your old C3 lamp will work again. First you need to shave off the 2 bumps on one side of the plastic base - the original bulb has a bump in the center that slides into the recess of the bulb (see image). The replacement Sylvania bulb fits without scraping the two ribs if you push it in there, but the bulb will tilt towards the front of the lens. I used a utility knife and it took me a few minutes to shave the bumps. 2nd and semi optional, you need

I have two sconces in my bathroom that use these bulbs. One blew up after almost five years of use. I bought a replacement not realizing that I had warm bulbs and the one I bought was cold. And it was VERY cool and gave off an eerie blue glow that definitely didn't match the warm yellow glow of other sconces. I searched my entire city and couldn't find a single warm lightbulb that worked in a sconce, so I turned to Revain and quickly found the exact lightbulb I needed. I ordered it and it…
