Silverlite [Plug&Play] 5w LED PL Bulb GX23-2 Pin Base,13w CFL Equivalent,500LM,Cool White(5000k),Driven by 120-277V and CFL Ballast,Horizontal Recessed,180° Rotatable,UL Listed

Very nice light but DOES NOT FIT AS REPLACEMENT OF 13W OTT LIGHT!Base does not fit and it cannot be altered to do so.NOT FOR OTT LIGHT!

Which means it only light from one side, another side is a heat sink. It looks weird.

Somehow I stumbled on this brand of GX23-2 Pin Base,18w CFL Equivalent. I'd been using Sylvania CFL's and I was not happy. You may or may not have this same problem, but removing them was scary. It takes a considerable amount of force to remove them once they've burned out and that's what scared me every time. They are fragile thin glass that can break with ease. The last thing I wanted to do was squeeze too hard on one of them and be in the hospital getting stitches.These bulbs are made of plastic so gripping them is no problem. And they seem to install easier. They definitely are brighter.The only negative is that the bulbs are uni-directional. They only shine light one way, so you need two installed per light fixture to get good light coverage. For me it's not a big deal because each of my light fixtures is made for two GX23-2 Pin Base lights.I'm glad I found these and they're well worth the price.

Best bulbs to place over the bathroom and kitchen areas as recessed replacement lights. The CFL bulbs have proven to be quite expensive to replace as our family keeps turning them on and off, burning them out within a few months time. Time to switch out with LED, in hope they will be much better in the durability department.At 25W, CFL couldn't match the 7W LED. 7W @ 5000K is perfect for just nightlighting in the kitchen. Not too bright, not too dim. If you're using over the bathtub as a mood light, go for something warmer in the 3500K at 4W to 5W. But if you're using it for single light lighting in the bathroom, 7W @ 5000K is a good start. I would say 10W to 15W @5000K or 8W to 10W @ 6000K. Of course, each person has his/her personal preferences.Remember, the light is facing 1 direction (outwards/sideway). If it's sitting above you, Most of the brightness will be hitting the metallic sidewall before the reflection provides the downwards brightness. Not a whole lot of option at this moment for GX23 (2-pins) version. You may need to properly measure the amount of headspace for the light to be inserted. At 5.9 inches (not 5.7 inches), I have to push the mounting bracket out of its retainer groves upwards. The light rests above my glass cover, but still fits inside the housing.

I have mixed feelings about this product.The first set I bought were used in my bathroom light fixture. They worked great, instant on, brighter than the originals, I was very happy.I had specifically used these bulbs because I wanted an LED replacement, but I rent an apartment and am not in a position where I could remove the ballast. Apparently, I got lucky with the first set and the bathroom fixture has a magnetic ballast.When it came time to replace the bulbs in the living room fixture I happily ordered another set. Well, not so lucky this time. The bulbs flickered, sputtered, and then burned out (complete with burnt plastic and smoke - see pictures).After that I re-read the ad. It does say specifically for use with 'magnetic ballasts'. It would have been nice if they had mentioned that it DOES NOT WORK WITH ELECTRONIC BALLAST! a little more prominently (and will catch fire).Other than that, it is a good product.Anyway, $25 worth of dead bulbs later and now it looks as if I have go back to crappy CFL's.

I ordered the 3000K to match all the LEDs throughout my home. Instant on, no flicker. Note this bulb only works with magnetic ballasts. I used the tip I found online to take a photo with smart phone of the FCL bulb to tell if fixture had electronic or magnetic ballasts. From that it looked like it might be electronic but I gave it a try anyway and it worked perfectly. Clearly my ballast was magnetic. Installation was simply plugging it in. Loved that part. Even though this bulb is one sided, the reflector in the fixture disperses the light virtually 360. Photos show the reflector and both sides of the bulb/cooling fin side and bulb side. Couldn't be happier with this purchase.

This bulb replaced a 9 watt PL style bulb in an older non-electronic ballast outdoor fixture. (I believe it is required to rewire fixtures with electronic ballasts to bypass the ballast and make direct connection to the feed power). It is noticeably brighter and throws it's light in a 180 degree pattern with most of the light concentrated in the middle 120 degrees or so. The bulb swivels 90 degrees so it can be aimed regardless of the orientation of the socket. I got this light because fluorescent PL bulbs give off less light when the temperature goes below 10 degrees or so and often start to blink on and off in minus temperatures. This LED light is not affected by temperature so that the light output is the same. It has been working satisfactorily for several months now.

This thing worked when I installed it, but make sure that you want light on one side of the bulb only. It only projects light from the front aide.Also, I expected it to be brighter as per the Lyman’s specified. It was no lighter than my 13w CF bulb that it was meant to replace.I had no idea it was only one sided. I’ll-suites for the application
