Fluorescent lamps come in many variety, ranging from 2,700K to 6,500K and even outside that range for specialized applications and CRI from low 50's to high 90's.halogen lighting blows away flourescent, period.. people only use FL because it's cheaper, and sometimes because it's cooler, but mostly cheaper is the only reason the technology exists. I get a headache almost instantly from FL. lighting.. it does have a nice side-effect of having no shadow with the 4' or 8' tubes.. i'll take the shadows over the headaches.
When people say "the fluorescent type" they more often than not mean 4100K, 62 CRI cool white that has been around since the 1950's which was operated on a magnetic ballast. Today, many installations use 4100K(this is a matter of choice) 85 CRI lamps operated on an electronic ballast. Actually, the old 40W cool white lamps are banned, because they are inefficient compared to newer types.
Well diffused light
20,000+ hours of average life
Moderate initial cost
Cost means a great deal in world. Do you realize how much it would cost in maintenance and energy cost in institutions, offices and stores if they used halogen lamps? Most of the cost is for energy, so the additional side-harm besides cost is environmental impact. Would you prefer halogen if it cuts $150,000 into the profit each year? I doubt it.
IRC is used to improve efficiency of halogen lamps where fluorescent lamps wouldn't be ideal, such as accent lighting and other applications needing spot or collimated light.IRC was developed because people prefer halogen to flourescent.. even IRC doesn't touch FL for efficiency, probably 1/2 as efficient, so where's the logic?
I agree that things will be leaning toward LED taking over lighting, but maybe never incan.. LED 'feels' like FL.. it will take over the FL market as it becomes more cost effective to use LED vs FL.. but the shops that really want their stuff to sell will use lighting that makes it look better and for now that is halogen lighting!
That is one of the applications where halogen lamps is preferred, because, improved merchadise apperance means more sale and more sale means more profit. Such practice would be phased out if the increase in profit dosen't surpass increase in energy cost and this is why you only see them in high profit visual appeal merchandise.
