This might be a solution to getting the beneficial effects of sunlight on gloomy days...

You will have to have a source of electricity, of course, but the type of light it gives off could help us all avoid "seasonal affective disorder" otherwise known as "the blues" of winter lack of sunlight...

Plus, a useful life of 40 years doesn't hurt, either.

The only thing unclear is whether each bulb gives off 60 watts or if it takes all five bulbs to create 60 watts.  So, if you are interested, clarify that point.  $150 is a lot to spend to find out that you are only getting 60 watts out of five bulbs.  But, still, you could create a "sunlight" room to recharge yourself. 

I wonder if it is the type of light that would generate Vitamin D in your skin.  Anyone have any ideas as to that?  If it does, then you wouldn't need to stock extra Vitamin D, a value added making this light bulb worth more.  I'll contact this company and see if they know.

Delete Comment Thanks Rosemary, yes they are LED. Nobody uses LED for growing plants they are an excellent source for illumination and save energy. Therefore, if light types are good for plants I thought it be good for human health too, I guess.

[Cheryl Nelson]

Thanks, Rosemary.

These are LED light. Unless I am mistaken, these light do not emit UV light with is the spectrum the body needs to produce vitamin D. Tanning booth emit UVB and some model UVA. If people are tanning too often, they may run the risk of developing skin cancer. Tanning is now consider addictive to some people because it has an effect on their brain that makes them crave tanning even if they have skin cancer.

Ok in your sun tanning room you could build a rocket stove

to keep warm with as little wood as possible!

What info, Alex?

Sonny, that's a good idea for small areas.

[Alex Cortes]

Where did my info go .....

Dr. Mercola sells special lighting devices that prevent winter blues (his stuff is expensive though).  He even advocates sun tanning with certain light and sells a tanning booth with these special bulbs.  Anyone want a tan all year round? lol

[Sonny Sisomphou]

Oh, and it's a cheaper way too. 60 watt probably around 20 dollars.

You be better off using a lighting tubes made for aquariums because it concentrate the lights to a small area, hence, so that your aquarium get most of the lights it needs and not waste it's energy, We can sit under these type of lights as if we were the fish tank and received most of the wattage it giving out. Normal light bulbs and tubes have their light spread out that is why they are use to light up rooms and not good for aquariums. Since these specialised design light tubes make my aquatic plants grow brilliantly I guess it's also good for human as far as vitamin D is concerned. Just my two cents and can't really say I make sense.
