Mini Spiral Cfl Light Bulbs – If you haven’t given the subject of lighting much idea lately that’s probably because, in common with the majority of people, the phasing out of traditional incandescent light bulbs has not been exactly uppermost on your mind. Which isn’t really all that surprising; having the ability to switch the lights on at will hardly appears to be a major thing. We all do it all the time and as priorities move the whole business of lighting is comfortably off the radar. Yet the demise of the incandescent light bulb continues quietly yet relentlessly and at under a couple of years now the sole products stocked on shelves will probably likely be low energy light bulbs, of which there are two kinds: CFLs (Compact Fluorescent Lamps) and LEDs (Light Emitting Diodes).
Presently, the majority of low energy light bulbs available are CFLs which are some 4 times more efficient than incandescent bulbs (i.e. they just waste about 25 percent of the energy as heating, compared to 90 percent). However, CFLs are widely disliked by consumers, manufacturers, and environmentalists. They have very poor aesthetic qualities (not really want you to need for lighting), they are awkward to eliminate safely as a result of their mercury content, and they are complex and costly to manufacture.
LEDs on the other hand score well on these points and quite a few more besides, the most evident of which is that LEDs are not just 10 times more effective than incandescents at present, however they double in performance every 18 months or so. |} The implications of the (known as Haitz’s Law) are astounding; in 3 years we must expect to determine LED light bulbs that are 40 times more effective. It is no wonder that the lighting industry has en-masse chosen to abandon CFL growth and focus on LEDs.
So should you be purchasing LED light bulbs right now? And since modern LEDs last over 50,000 hours (compared to 2,000 for routine light bulbs) the return on investment only keeps rolling in.
Today some people will assert that it makes sense to wait until LEDs are both cheaper and much more effective, but in the event that you run the mathematics you may find that in actuality, it’s better to substitute perfectly usable light bulbs with LEDs today and then aim to replace them at a few decades, even though they will still have decades of life left. How so? Since the price of electrical lighting pretty much equates to the price of electricity – it’s all in managing costs, not the hardware price.
