Gu10 Light Bulb Change – If you haven’t given the subject of lighting much idea lately that’s probably because, in common with most people, the phasing out of conventional incandescent light bulbs has not been precisely uppermost in your mind. That is not really all that surprising; having the ability to change the lights at will hardly seems like a major thing. We do it all the time and as priorities go the entire company of light is comfortably off the radar.
Currently, the majority of low energy light bulbs accessible are CFLs that are a few 4 times more efficient than incandescent bulbs (i.e. they only waste about 25 percent of their energy as heat, in comparison to 90%). However, CFLs are commonly disliked by consumers, manufacturers, and environmentalists. They have quite poor aesthetic qualities (not actually want you to need for light), they’re awkward to eliminate safely thanks to their mercury content, and they’re complex and expensive to manufacture.
LEDs on the other hand score well on these points and quite a few more besides, the most obvious of which is that LEDs aren’t only 10 times more effective than incandescents at current, but they double in performance every 18 months or so. |} The implications of this (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 industry has en-masse chosen to abandon CFL growth and focus on LEDs.
So if you be purchasing LED light bulbs at the moment? This very much depends upon if you balk at the prices offered (in comparison to both incandescent and CFL light bulbs, LEDs still cost several times more to purchase) or if you can do the math and realize that the savings in electricity consumption will more than repay the investment within the first year or two. And because modern LEDs last over 50,000 hours (compared to 2,000 for regular light bulbs) the yield on investment just keeps rolling.
Now some people will argue that it is sensible to wait till LEDs are both cheaper and much more effective, but again if you run the mathematics you will discover that in actuality, it’s far better to replace perfectly functional light bulbs with LEDs now and then aim to replace them at a couple of years, though they will still have years of life left. How so? Since the cost of electrical lighting pretty much equates to the cost of electricity – it’s all in operating costs, not the hardware cost.
