Stick Up Light Bulbs – In case you haven’t given the subject of lighting much thought recently that’s probably because, in common with the majority of folk, the phasing out of traditional incandescent light bulbs hasn’t been exactly uppermost in your thoughts. That is not really all that surprising; being able to switch the lights on at will hardly seems like a big thing. We all do it all of the time and as priorities move the entire business of lighting is off the radar.
Currently, nearly all low energy light bulbs accessible are CFLs that are some 4 times more efficient than incandescent bulbs (i.e. they just waste about 25 percent of their energy as heating, in comparison to 90 percent). But, CFLs are widely disliked by consumers, manufacturers, and environmentalists. They have quite poor aesthetic qualities (not actually want you to want for lighting), they’re awkward to dispose of safely as a result of their mercury content, and they’re complicated and expensive to manufacture.
LEDs on the other hand score well on all these points and a few more besides, the most obvious 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 consequences of this (called Haitz’s Law) are astonishing; in 3 years we should expect to see LED light bulbs which are 40 times more effective. It’s no wonder that the lighting industry has en-masse elected to abandon CFL development and concentrate on LEDs.
So should you be purchasing LED light bulbs right now? This very much depends upon whether you balk at the prices quoted (in comparison to both incandescent and CFL light bulbs, LEDs still cost several times more to purchase) or whether you are able to do the math and realize that the savings in electricity consumption will more than repay the investment within the first couple of years. And because contemporary LEDs continue over 50,000 hours (compared to 2,000 for regular light bulbs) the return on investment just keeps rolling.
Now some folk will assert that it makes sense to wait until LEDs are both more economical and much more effective, but again if you run the mathematics you may find that in actuality, it’s far better to replace 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 cost of electrical lighting pretty much equates to the cost of electricity – it’s all in managing costs, not the hardware cost.
