As of 4-12-14 there is a 23 Watt screw in bulb supposedly equal to 100 Watt.
It is likely there are higher watt bulbs in the flourescent screw in type available today.
Halogen is about 20% brighter.
a compact electronic ballast in the base of the lamp
They can. The base gets hot and I have had them pop holes in the tube.
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. The lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
Not at the present time. Flourescents can't be dimmed with a conventional wall dimmer ... because of that, I wouldn't hold your breath waiting.
"Compact fluorescent lamps" (or, more commonly CFLs) sold direct to consumers for installation in a standard screw-in socket have an integral ballast built into the base. The ballast converts and controls the line voltage from the socket to properly drive the fluorescent lamp. Ballasts are generally fairly complex circuitry. All fluorescent lamps require a ballast. However, most lamps used commercially ("ordinary fluorescent lamps") do not have the ballasts built into them; rather, the ballasts are hidden somewhere in the fixture.
A candelabra candle is a candle which has a base and it has branches that hold one or more candles. They are some candelabra's that are used in Jewish religion too. http://en.wikipedia.org/wiki/Candelabra
An E-11 indicates it has a mini candelabra base bulb. I am not familiar with any d11s.
As long as the CFL has an intermediate base it can be interchangeable with any ordinary light bulb that has an intermediate base. Look on the packaging as to comparability. Look on the box for equivilant outputs between lamps to compare wattage bulbs to CFL's.
Its A Candelabra base bulb :-) However, one can find "medium" sized base bulbs marked "Type B."
The PLC in PLC light bulbs stands for Philip Lighting Clusters. PLC light bulbs are compact fluorescent lamps. They are a cluster of lighting tubes that come with a 2-pin or 4-pin base.
No, this is not true. The spiral-type compact fluorescent bulbs can be operated in any orientation provided that there is sufficient air circulation around the bulb. But if you put the bulb in a fixed enclosure then it will last longer if the base is facing downwards so that the heat is conducted away from the electronics in the ballast. Always follow the manufacturers's directions - usually written on the bulb. No, this is not true.
