Is there really a difference between this and a regular incandescent light bulb? I have read that regular incandescent bulbs are full spectrum.

regular bulbs are not full spectrum unless its stated on the package. these are good though i ordered one a few months ago and with about 6-8 hours of use every day its still going.

i didn't buzz when i used regular light bulbs or cfl. i did stop working completely after two weeks. second one that failed, just to warn you.

I believe you are right and the difference is in LED bulb. We have this one and can't be happier. Its really quiet and efficient! No more moisture in my husband's bathroom!

Mine has a regular bulb,although at the bottom of the description it says led bulbs last longer.

my incandescent bulb was brighter than the dorcy. i would have returned the dorcy, but shipping would have cost as much as the bulb. i don't recommend using it to replace anything.

I have used both dimmable LED bulbs and regular 60 watt clear. The lamp makes the bulbs 1/2 as bright normally. When motion triggered, the lights go to full light. It does have a photo sensor and turns on at dusk and off at dawn.

I used the bulb in a dimmable light and found that it works, but does not reduce the brightness much because it is not that bright to begin with. At full brightness it is still dimmer than a traditional 3 watt bulb. When dimmed, the flame effect does not flicker as much. It may not be worth dimming these bulbs, unless you are using these bulbs on a circuit with a dimmer already installed.

Hi - I think it will depend on what other lights you are using. The light is on the white side of the spectrum and noticably more white than traditional incandescents. It is not as harsh as the ones with a really white light. I have been using one bulb 24 hrs a day this winter in a room we use occasionally. It is fine, but I intend to replace it with a softer light this spring when I move the plants outdoors. I hope this helps.

It's at the high end of wattage, but yes. However, 100 Watt Incandescent bulbs are being phased out in favor of flourescent bulbs and may be hard to find. More typically, a regular bulb would be 75 watts or even 60 watts.

yes, it is at a different light spectrum from regular incandescent bulbs, fluorescent bulbs give a true black-light experience. The light should cover 400 sq ft about a size of 20x20 ft room. If you want the very bright glow of neon colors and white objects I suggest at least two of them or one 48'' inch flourescent fixture. If you are looking to use this light to illuminate a room that has dark colors such as browns , blacks and blues and walls are a dark color too, the light will not illuminate these objects. If you are using it for a party, be sure to have other lights available to turn on, when navigating thru the room yes, it is at a different light spectrum from regular incandescent bulbs, fluorescent bulbs give a true black-light experience.

These bulbs have special components inside to produce UVA light; other than that they are configured just like regular lightbulbs, except that they focus all the light into one spot rather than cast it all around. Personally, I have stopped using this style of bulb... If you get a decent fluorescent UV light (the 12" kind, not compact fluorescent, though!) you can use a regular lightbulb, as long as the temperature at your basking spot is high enough. I like this set up better because the fluorescent bulbs produce UVA and UVB, while this bulb will only produce UVA.

The light is very bright and has a great warmth and color to it. I don't think there is a noticeable difference to incandescent.

yes, just yer regular ordinary bulb. I put in a cfl bulb and it looks good.

The bulbs are dimmable, but not as smooth a transition as an incandescent bulb. They dim, but at a certain point drop off rapidly. There may be some flicker at some point. The main problem for you may be their size. Because of the dimmable feature the base is larger than a non dimmable CFL, thereby extending the overall length and making the width slightly larger. Also, I just had one of the bulbs fail in a cold, unheated room.

I had to get LED bulbs, my electrician installed CFLs that were marked,"not for use with dimmer". He said they were, but I also saw the box they came in and it said not for use with dimmer. The LEDs cost more, but are engineered to last much longer than CFLs. I am looking at them now, and I think it was worth the money to get the LEDs. They seem brighter than the CFL bulbs also.

According to the Wikipedia entry on 'Incandescent light bulb': "The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared to the 60 lm/W of a compact fluorescent bulb."That would mean 20 lumens is about the same as a 1.25 watt incandescent bulb -- slightly less than 1/3 the light of a 4watt small incandescent nightlight. That's the theory anyway...

The answer is that a halogen lamp IS incandescent in that the light is produced by current flowing through a filament which is heated to a high temperature. The difference is that 'halogen' lamps operate at a higher temperature and have an internal atmosphere of a halogen gas (normally iodine or bromine or a combination) which allow the lamp's envelope to remain clear rather than being clouded by evaporated metal from the filament while regular 'incandescent' lamps have a semi-vacuum/inert atmosphere. Electrically the two lamps are identical.
