Question What is this CFL thing called?

Sorry, stupid question time.

I'm just trying to find out what this CFL Light Fixture thing is called so I can try to search for information on how to fix these, or better yet replace these damn things with something better. I've got about 100 of them in our 8,000 sq ft house and a full 10% of them don't work... they randomly go in and out.

It's the fixture that I'm wanting to research. It's got some sort of 4 pin CFL bulb in it (which the bulbs are another pain in the butt too... but I digress)

And if you have any links on info, that'd be great too

They are recessed lights. You could probably replace with 4-pin LED retrofit. Examples: http://www.planetbulb.com/led-litesp...ertical-4000k/

But I've replaced bulbs in these and they still go in and out... I'm thinking the recessed light things themselves are bad .. so just putting a different bulb won't really fix the problem

And, starting to take this thing apart and doing more reading, there are multiple parts to this thing. Looks like the outside part is the "Fixture", but I'm still confused on the inside parts: a housing? or a ballast?

What you pictured is a florescent bulb that requires an external ballast. The screw-in CFL bulbs have an internal ballast. The non-ballasted CFLs may only be used in a fixture that has a proper ballast and I well know the frustration of changing the bulb and the light still refuses to work. It was more than 20 years, maybe more than 30 years, ago when i installed a couple of outside fixtures at my parent's house and they were nothing but a problem. As a result i utterly refuse to even consider a CFL fixture that uses an external (from the bulb) ballast.

Some of the bulbs may be of poor quality leading to short life. Best thing I can think of is make a note of who makes them and stay away from the poorer brands.

Sometimes you can remove the existing ballast (a piece of electronics or a transformer-like item or an item perhaps the size and shape of a hot dog roll or a cigarete pack or a cigarette lighter depending on fixture wattage). Think of it as part of the fixture "guts." Then you could install a different technology such as an LED unit that was not specifically a retrofit. But now you are "Kitbashing" as opposed to just assembling and/or installing.

One caution, although LEDs give off far less heat than incandescents, some LEDs have a shorter life due to overheating when installed base up in an enclosed fixture.

Here is a link to can lights similar to yours. These are Juno and use 6-pin Triple Tube CFL bulbs.

Product-Family

You can see that the ballast would be very difficult to get to if needed replaced. If they are the remodel type, you could remove the entire fixture, but your lights are probably new construction type and nailed in.

You're not dimming these are you? There are CFL Ballasts that are dimmable, but I doubt if 100 would be installed due to cost. So going out on a limb, most triple tube CFL's cannot be dimmed.

Just a thought, could the fixtures be covered in insulation causing the thermal protector to trip,that could cause the ON /OFF situation you are having.

These recessed fluorescent fixtures have electronic ballasts and you most likely have some bad ballasts. Who is the manufacturer of the fixtures? These fixtures work best when once turned on they are left on for long periods like in a retail store. The ballasts can be accessed and changed through the fixture, but sometimes it is a challenge to disassemble the fixture from the inside just to access the ballast. If we knew the manufacturer and catalog number of the ballast maybe we could help. It is possible there is a brand specific peculiarity to these ballasts and their behavior is trying to communicate to you. It's also possible the ballasts have been recalled, but without the manufacturers name and model number it's impossible to tell.
