I just looked at some of the screw in halogen bulbs that should fit
any fixture made for common indecesant bulbs.
They claim more light for less energy.
When you read the wattage and lumens rating, it's obvious their claim
is a lie.
A standard indecesant bulb actually puts out about 1% to 2% MORE
lumens than the halogen of the same wattage.
And the bulb uses the SAME wattage.
It's something like a 100 watt bulb uses 100 watts whether it's
indecesant or halogen. The ind bulb produces somethingh like 1380
lumens, the hal light produces 1365 lumens.
The ind. bulb costs around 50 cents, the halogen bulb costs about $5.
SO, what's the point. There is no energy savings at all, 100 watts is
100 watts. And after you pay 10 times as much for the halogen, you
actually get 1% or 2% less light. The only advantage I saw was that
the halogen is rated to last 1 1/2 times that of an ind. bulb. BIG
DEAL..... First of all, those life expectency numbers are always
exaggerated anyhow. And you could buy TEN ind. bulbs for the cost of
I just dont see the point of these halogens at all, other than to make
money for the seller.
the OP has no idea what he's talking about.
11 watt CF bulbs are the equivalent of a 60 watt incandescent, and a 25 watt
CF is the equivalent of 100 watts, in lumens, not watts. it still consumes
about 25% of the original.
the local IKEA store has a wall where half the wall is made of CF bulbs and
the other is made of incandescent bulbs, and there's a watt meter showing
each half's consumption.
obviously they're not equal.
no JJ halogen and zenon gas are different, and HID on cars are a
different light altogether. Lights on cars have been standard halogen
for years. Think of the little 2" spotlights ,mr16 with a whiter light
,those are halogen, and the burn hot. Most high quality display
lighting is halogen. Zenon ,HID on cars is slightly bluer.
Halogen bulbs are still incandescent. HID are gas discharge lamps (Xenon
arc) -- same general principle (I am guessing) as neon advertising signs.

following message into cyberspace:
Don't forget that, unless you're a jewelry store, lighting usually represents
less than 20% of your total electric bill. If you're looking to save energy,
invest in replacing the real energy wasters, like old refrigeratiors, unused
freezers, dehumidifiers , air-conditioners.
that's not the only reason to use CF bulbs. My reason is simple: the lamp I
have accepts 3 bulbs of maximum 60 watts each and I want more light. 100
watts would be too hot.
Another reason is the house wiring is very old and there are many circuits
connected to one wire. 300 watts in my lamp is too much draw.
I thought I clearly specified HALOGEN..... (duh)
Compact florescent is a whole different matter, and yes, those are a
great energy saver. My whole house has them, even the garage. I work
at night quite a bit, and I am not real good about shutting lights
off. I now save nearly $10 a month from what my electric bill used to
I wondered about that myself. I've had a halogen desk lamp for about
ten years, and it's only a 20W bulb. Previously, I had a regular bulb
desk lamp there, and I used either a 40 or 60W bulb, yet I get by fine
with the 20W halogen.
I like the enough that I've done repair on the thing to keep it running.
It was a gift, but don't think it was bottom of the line. Yet, a few
years in I had to replace the on-off switch. Then, my fault, I blew
the fuse in the transformer, so I had to hack open the AC adaptor and
fix that. Luckily there was a fuse in there separate from the transformer,
and it got back in working order, though the case of the adaptor is kind of
messy. The lamp is a little shaky in design, since it uses the mechanical
parts to convey the low voltage to the bulb. I had to manufacture a bit
to replace a bit that just wore out, and it was less then perfect. When the
replacement wore out too, I just took the mechanical arm out of the picture,
and ran wire from the AC adaptor to the socket. It's working better than
it has in some years, since the scheme even before I had to replace the part
suffered from less than perfect electrical contact between sections of the
arm. Now it's nice and steady, and I can see it lasted for a good many years.
If I wasn't getting something out of it, and not only does the light
seem good for the wattage but it's a smaller and easier to manipulate
the late, I sure wouldn't have bothered with all this to keep it running.
I have some 30 watt (or less, could be 28) CF bulbs made by Globo. They are
supposed to be the equivalent of 100 watts and they are indeed very bright.
They're also very resistant. My dad dropped one while changing it, from
around 6 or 7 feet, and the thing still works great, no crack or anything.
