Compact fluorescent lamp replacement?

[MBfreak]

Hi to all,
no idea if this is a relevant Q on a US forum, but here goes:
Some 10-15 years ago when normal lamps were being replaced by fluorescent types there came a type that has a 2 or 4 pin socket plug in , the ballast is fixed in the fitting. The ballast is of electronic type.
I have looked for LED replacements that is a straight swap, ie running the LED thru the "electronic" ballast. The few LED replacements I have found are overly expensive and not at all as efficient as traditional screw in LED replacement screw ins.

A 9 W plug in gives only about 900 Lumens, the 9 W Fluorescent is rated at 1400-1800 Lumens.

All input most welcome, I am on the very beginning of the learning curve here.

The fluorescent types contains mercury vapor I see, which is quite astonishing!

Ola,
There are LED lamps that will plug into a 4 pin socket and use the ballast as a power source. They are made by Philips, Lunera, Green Creative and others. Finding one that works in a 2 pin socket, using the existing ballast, is much more difficult. There are alot of these types of lamps that work with the ballast bypassed. Look at www.led-llc.com for a good selection.
Other options exist. There are LED trim kits, which fit into downlights and give the appearance of a new fixture.
You wont need as many lumens from the LED lamp (depending on your fixture style) because of the directional nature of the beam. Alot of lumens from CFL lamps are lost or wasted. I have never seen a 9w fluorescent that can produce 1400 lumens.
Good luck,

Cybr is correct....

But, unless that fixture has some special meaning, you would be ahead replacing it with an ED fixture.

I had some of the same lights you were talking about....I've since replaced them

I have put A type lamp bases in some fixtures that had large enough globes. You can then use standard screw in LED bulbs, as many as you can fit. Bypass any ballasts and electronics and wire for 120V directly.
