Led Light Bulbs Growing Plants – If you haven’t given the subject of lighting much thought lately that’s probably because, in common with most people, the phasing out of conventional incandescent light bulbs hasn’t been exactly uppermost in thoughts. That isn’t really all that surprising; having the ability to switch the lights on at will hardly seems like a major deal. We 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 proceeds quietly yet relentlessly and in under a couple of years now the sole products carried on shelves will be low energy light bulbs, of which there are two kinds: CFLs (Compact Fluorescent Lamps) and LEDs (Light Emitting Diodes).
Currently, nearly all low energy light bulbs available are CFLs that are a few four times more efficient than incandescent bulbs (i.e. they just waste about 25 percent of their energy as heat, compared to 90 percent). But, CFLs are commonly disliked by customers, producers, and environmentalists. They have quite poor aesthetic qualities (not really want you to want for lighting), they are awkward to dispose of safely as a result of their mercury content, and they are complex and expensive to fabricate.
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 current, but they double in performance every 18 months or so. |} The implications of the (called Haitz’s Law) are astonishing; in 3 years we must expect to determine LED light bulbs which are 40 times more effective. It’s no wonder that the lighting business has en-masse chosen to abandon CFL growth and focus on LEDs.
So if you be purchasing LED light bulbs right now? This very much depends upon whether you balk at the costs offered (compared to both incandescent and CFL light bulbs, LEDs still cost several times more to buy) or whether 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 because contemporary LEDs last over 50,000 hours (compared to 2,000 for routine light bulbs) the yield on investment just keeps rolling.
Now some people will assert that it is sensible to wait until LEDs are both more economical and even more effective, but again in the event that you run the mathematics you may discover that in fact, it’s better to substitute perfectly functional light bulbs with LEDs now and then plan to replace them in a few decades, though they will still have decades of life. How so? Since the price of electrical lighting pretty much equates to the price of power – it is all in operating costs, not the hardware price.
