My preference is the lighting that provides the best light for me needs. I have many different types of light bulbs in my home.  The one in my office is very bright. I do not believe it is any of those you have listed. 

I am using LED all the way!

I am still preferential towards a torch.

I like the LED bulbs because they are such money savers but I will always appreciate the warmth of the good old incandescent.

I tend to be an LED guy.

If one has limited budget try incandescent. These fluorescent lights do not last that long but the price is OK. 

LED is supposed to last 100,000 hours. It consumes 10% of electricity. But it is very costly.   Well, they said the same of all other lights that they have long long life.  Puff gone quickly.

LED casts a nice crisp light 

I'd say LED...

LED all the way, the fluorescent mess with my eyes

It depends.  On the room.  On the purpose. On the fixture.   

Fred Griffin - should be NO Halogen and prefer LED or Incandescent.

LED and nothing else for me!  

The only fixtures that have any other kind of bulbs (Halogen) in them are my outdoor flood lights and they just haven't had to be changed out since we moved in - I'll probably change them to LEDs too!

We like LED, and in offices we always had full spectrum fluorescents, because they keep you healthier and you don't look grey.  A

I use LED and fluorescent as they last longer and are energy efficient. I have not had a client ask for a recommendation.

LED

We use fluorescent in the buildings and LED's in camp where electricity is a premium.

I make note of what exists in their new home and present them with a box of appropriate LED lamps. And if the under-cabinet lighting is insufficient or non-existent, I include an LED strip for their pleasure.

I agree with Bob "RealMan" Timm and Nina Hollander

I still prefer my incandescents (probably not overly pc of me). Hate fluorescent lights. I do use halogen and led in the appropriate fixtures.

Flourescents gives me a headache.   Led's are my favorite

I'm with LED!!

I am a fluorescent fan...

I prefer LED lighting

Hah, you cannot even get a straight answer at the local hardware; I have no idea!

It depends on the specific application that the lighting will be used in.  The homeowner may also have particular preferences, medical issues or there may be other matters to take into account.

I need to see what other have to say.  

tungsten my favorite

I prefer LED in the 5000 kelvin range to mimic natural light.

CFLs have been linked to cancer.  I have no experience with Tungsten.  Halogen I've never liked for indoors, had them in some lamps and god forbid you touch the bulb, your oils will mess it up.

My favorite is still the incandescent, but I've gone to all LEDs in my house.  I've measured the temperature of LED and incandescent bulbs in my ceiling can lights, in the same room.  The LEDs were 1/4 the temperature of the incandescents.  Made for my rooms being a little cooler this last summer over the one prior.

I wouldn't go for LED over incancdescent in a flip home though, since the cost is so much higher.  You really get the cost savings over time and in a flip no one is going to pay more because of the bulbs you use.

I prefer the new flourescent myself - I have them no in all my rooms and it's much better lighting

Fred Griffin As I run out of incandescent bulbs, I've been using fluorescent ones. I put one in my outdoor lamp post and it lasted well over a year. Just replaced it a couple of weeks ago.

warm anything I guess. I hate it when sellers use 25w maximum so I have to maneuver thru the cave.

I prefer the LED bulbs, but be careful as to the type of light - I like the soft light that mimics the older incandescent ones.

The world is confused about this !
