Top 10 Led Light Bulbs – In case you haven’t given the subject of lighting much thought lately that’s likely because, in common with most folk, the phasing out of conventional incandescent light bulbs has not been exactly uppermost on thoughts. Which is not really all that surprising; having the ability to switch the lights at will hardly seems like a big deal. We all do it all of the time and as priorities go the entire business of lighting is comfortably off the radar.
Presently, nearly all low energy light bulbs available are CFLs that are some four times more efficient than incandescent bulbs (i.e. they only waste about 25% of their energy as heating, compared to 90 percent). But, CFLs are widely disliked by customers, producers, and environmentalists. They have quite poor aesthetic qualities (not actually want you to want for lighting), they are awkward to dispose of safely as a result of their mercury content, and they are complicated and expensive to fabricate.
LEDs on the other hand score well on all these points and a few more besides, the most obvious of which is that LEDs aren’t only 10 times more effective than incandescents at current, however they double in performance every 18 months or so. |} The consequences of the (called Haitz’s Law) are astonishing; in 3 years we should expect to see LED light bulbs which are 40 times more effective. It is no wonder that the lighting business has en-masse elected to abandon CFL growth and focus on LEDs.
So if you be buying LED light bulbs at the moment? And because contemporary LEDs continue over 50,000 hours (compared to 2,000 for regular light bulbs) the return on investment only keeps rolling.
Today some folk will assert that it is sensible to wait until LEDs are both cheaper and even more effective, but again in the event that you run the mathematics you will find that in fact, it’s better to replace perfectly usable light bulbs with LEDs now and then aim to replace them in a few years, even though they will still have years of life. How so? Because the price of electrical lighting pretty much equates to the price of electricity – it is all in operating costs, not the hardware price.
