Philips Compact Fluorescent Light Bulb (383109 / PL-C13W/27/USA/ALTO)

I bought a house recently that had garage light fixtures that used these bulbs, which I had never seen before. I used the product codes on the old light bulbs to locate new ones online. These matched perfectly and work great, I only needed 3 at this time but bought 6 so I would have some more when others burn out.

Worked perfectly!

I was happy to find the right light bulb after a long search. The ordering process was easy and they arrived sooner than we expected.

It worked fine until I decided to replace it with a different new canister that comes equipped with the bulb attached.

It was difficult to change bulb being it sits above the shower stall.

fits perfectly, would purchase from LightBulbs.com again.

Needed replacement bulbs for my Panasonic whisper fan and light.
The Panasonic bulbs that came with the fan worked great but they are no longer made.
We have 3 fans but only 1 original bulb.

Only the TCP and original Panasonic bulb have no flicker or hum on startup. I can't comment on the GE bulb because I broke it.

Eiko 15576 (3,500K): Flickers a few seconds when starting up. Ok afterwards. Annoys me and has been relagated to the laundry room. This is the first replacement bulb we tried. Hate it in the bathroom but am tolerating it in the laundry room where I leave the light on for longer periods of time. My dislike for this bulb is why I bought 4 oth
er bulbs at the same time -- I put up with that horrible flicker for long enough. If you can put up with a hum and
flicker that eventually go away, it is the least expensive bulb we tried.

TCP 32015 (2700K): Great bulb. Starts up even faster than the original Panasonic bulb and I thought the Panasonic
bulb started up fast. No flicker. No hum.

GE 97587 (3000K): Broke it before installing it. Which is too bad because I wanted to compare the color temperatur
es.

Philips 383109 (2700K): Flickers when starting up.

Sylvania 20480 (2700K): Flickers when starting up.

The light bulb has difficulty actually turning on, and flickers very badly as it does. It is like a strobe light of varying light levels, and often takes about 15-20 seconds to fully come on turn on. Once it is on, I haven't had problems with flickering. I'm not impressed, and unfortunately, these are the only light bulbs my light fixture will use as is.
