Tanning Bed Light Bulbs – If you haven’t given the field of lighting much idea lately that’s likely because, in common with most people, the phasing out of conventional incandescent light bulbs has not been exactly uppermost on mind. That is not really all that surprising; being able to switch the lights on at will hardly seems like a major deal. We all do it all of the time and as priorities move the entire company of lighting is comfortably off the radar.
Currently, nearly all low energy light bulbs accessible are CFLs which are a few four times more efficient than incandescent bulbs (i.e. they only waste about 25 percent of their energy as heat, compared to 90%). However, CFLs are widely disliked by customers, manufacturers, and environmentalists. They have quite poor aesthetic qualities (not really want you to want for lighting), they are awkward to eliminate safely as a result of their mercury content, and they are complex and costly to fabricate.
LEDs on the other hand score well on all these points and a few more besides, the most evident of which is that LEDs aren’t only 10 times more efficient than incandescents at current, but they double in performance every 18 months or so. |} The consequences of this (known as Haitz’s Law) are astonishing; in 3 years we must expect to see LED light bulbs that are 40 times more efficient. It is no wonder that the lighting industry has en-masse chosen to abandon CFL growth and focus on LEDs.
So if you be purchasing LED light bulbs right now? That very much depends on if you shout at the costs quoted (compared to both incandescent and CFL light bulbs, LEDs still cost several times more to buy) or if you can do the math and realize that the savings in power consumption will more than repay the investment within the first year or two. And since modern LEDs continue over 50,000 hours (compared to 2,000 for regular light bulbs) the return on investment just keeps rolling in.
Today some people will argue that it makes sense to wait till LEDs are both more economical and much more efficient, but again if you run the mathematics you will discover that in fact, it’s better to replace perfectly functional light bulbs with LEDs now and then plan to replace them in a couple of years, though they will still have years of life left. How so? Because the cost of electrical lighting pretty much equates to the cost of power – it is all in operating costs, not the hardware cost.
