I have a 150 watt ceramic infrared heat bulb similar to this one http://www.amazon.com/Zoo-Med-ReptiCare-Ceramic-Infrared/dp/B0002AQCPK that I use next to my desk to help keep me warm. It produces no visible light, only heat. Sometimes I have the urge to stare at it, can it hurt my eyes from the infrared radiation, similar to how looking at a regular light bulb can hurt your eyes? I am also interested in how these bulbs work, and the type of infrared radiation they give off if someone can explain it to me.

I have a UK traffic light head with 3 halogen bulbs (12V AC). The bulbs it came with are just like G4 12V halogen bulbs, except that the legs are fractionally thicker. It seems like they are not G4 bulbs -- so what are they? [more inside]

My bathroom has six light bulbs in it and, to my shame, they're incandescents. I'd like to replace them with LEDs so I never have to think about them again. Which LED bulbs are most like your standard 60W incandescents? [more inside]

While changing a bulb in one of our rooms, replacing a LED with a CFL because of a need for brighter lighting in this work area, it suddenly hit me: Why does an LED light have a bulb? In both incandescent and CFLs, the bulbs trap gas (or vacuum as the case may be.) But why an LED? It doesn't use a gas and it doesn't need to operate in a near-vacuum for efficiency. Closer examination showed that the bulb was plastic and had no lensing effect.
This question is almost answered here.
Because of the question regarding heat sinks (which seem much reduced in modern LED lights, I'm guessing the answer is because they get hot. So I'm guessing that's what it is, though I also think that having a bulb makes it easier to screw into the socket. Taking these points together, I can imagine getting a burn if there was not bulb by brushing up agains an LED stalk that was on until a few seconds ago when you decided to unscrew it.
So...have I answered my own question or is there more behind the bulb?

Can I use a CFL or LED bulb in an outside flood light type fixture that is hooked up to an in-wall Intermatic timer? I was told no but I would like to confirm. If that is the case, I'd love a short explanation in plain English. I tried Googling but I'm still confused. [more inside]

One of the two halogen lightbulbs in my Wolf range hood needs to be replaced, but we cannot budge it. The bulb is very hard to grasp because it is almost flush with the sides and we can't get it ro turn. The other comes out no problem, so it's not like there is a special trick to removing them.
Ideas, suggestions, etc. greatly appreciated.

How do I change a lightbulb? Sounds like the start of a bad blonde joke, but I'm seriously struggling to work out how to change my blown halogen lights without breaking the halogen leads of bulb after bulb. [more inside]

Okay, need some help regarding a broken CFL (compact fluorescent lamp) in my 2-year-old son's room. I've looked through a couple of similar questions here, but this situation is a little different so I'm hoping for more specific insight. I've also already seen a lot of varying information relating to proper clean-up procedures, potential long-term contamination and adverse health effects, etc. I really need to know what I should be concerned about with regard to my son's health.

Looking for a gardening tool & have no idea what it is: seedling waterer? bonsai tool? It's a metal rosette like you'd see attached to a watering can, maybe 3" across, with a pencil-sized metal pipe leading to a squeezy rubber bulb on the end. [more inside]

Which CFL bulbs are the longest lasting and cheapest to buy? I'm concerned about saving money on my electric bill but not worried about mercury content (if lights are broken). Are there any CFL bulb giveaways
that are online?

I broke a compact fluorescent light bulb in my bedroom. Rudimentary cleanup, but I'm must
go to bed, and my husband's already asleep in there. I saw the scary "leave the room for 15 minutes" mercury warnings on the government cleanup page. Anybody know the science? How bad is this? [more inside]

I want to plant some Casablanca lily bulbs, so that I may cut them at various times and give them to the SO. I live in Los Angeles, and have sandy soil around my property at different degrees of sunniness and facing different cardinal directions, mostly directly against one wall or another. What should I know?

. I just priced out bulbs
for our Proxima X350 video projector. The stores I looked at want $350, about equal to the price used projectors are going for on eBay. If I shell out $350, am I getting ripped off? Since when did it cost so much to make a light bulb?

Fluorescent light problem:
I have a fluorescent light fixture in my bathroom using two, different-sized, doughnut-shaped bulbs. Lately it's been taking a long time to turn on (15-30 minutes) after I throw the switch in the morning. If the fixture has been running for a while, this warm-up time seems to go down. Does this sound like a ballast problem (and thus my landlord's problem), or a light-bulb problem (mine)? I'm leaning to ballast because the lights look fine once they start, but I haven't been able to find the same symptoms on the half dozen fluorescent lighting websites I've looked at so far.
