Of course! That's why they are being made compulsory

Note the 2012 date. Strike you there may well be something intrinsically harmful in the frequency of these things?

Use full spectrum

Ladies and gentlemen, You and I are standing on the threshold of a very historic event. Very shortly, you’ll be witness to the actual turning of a page in history. You’ll see something you’ve taken for granted every day of your life, slip slowly into the mist of the past. I’m talking about the common, run-of-the-mill, everyday light bulb. Earlier this year, Congress passed a bill that will literally outlaw the use of old-fashioned incandescent light bulbs. A recent news release stated that the new law is part of a massive governmental energy-saving program that will completely phase out the use of those energy-gobbling incandescent light bulbs by the year 2014. That’s right, starting in 2012 it will actually be against the law to use regular incandescent light bulbs. You might be wondering what on earth the government is up to now – going after a light bulb? I admit, it does sound pretty radical, but think abut this… Once the change is in effect, the boost in energy efficiency and savings will be at the very least a whopping 70% overall! And what does that mean for you? A 70% decrease in energy use translates into huge savings on your utility bill. Plus, it’s very good for the environment overall. That’s a win-win for you -- and the environment. So, the first to go will be the 100-watt bulb. And the transition will continue until the last 40-watt bulb is replaced in 2014. That’s just a little over 5 years! And the best part yet is… You’ll Be Able to Get More Health Benefits from Sunlight… They probably don’t even know it -- but the government is practically making it a law for you to get more of the healing benefits of sunlight into your life. In moderation, sunlight improves your immunity, prevents disease, increases intelligence, stimulates your metabolism, and boosts your energy level. Specifically, the full spectrum of the sun's light rays has been shown in medical and scientific studies to: Positively influence your risk of getting sick (there is a preponderance of evidence suggesting that decreased sun exposure is closely related to your risk of acquiring the flu, a common occurrence particularly during the colder months). Lower your blood pressure (in fact, the farther from the equator you live, the higher your blood pressure). Even help babies sleep better at night (this is great news for you parents out there). The problem is that getting adequate sunlight isn't easy these days. Most of us suffer from "sunlight starvation." We all need about one hour of unfiltered sunshine each day. Unfortunately, the majority of us don't even come close to receiving that amount.

Many UK sources but the bulb/ioniser combination looks interesting here
