Fluorescent Light Bulb Sleeves – In case you haven’t given the subject of lighting much thought recently that’s likely because, in common with most people, the phasing out of conventional incandescent light bulbs hasn’t been precisely uppermost on mind. Which is not 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 move the whole company of lighting is comfortably off the radar.
Presently, nearly all low energy light bulbs accessible are CFLs that are some four times more efficient than incandescent bulbs (i.e. they only waste about 25% of the energy as heating, in comparison to 90 percent). However, CFLs are commonly disliked by consumers, manufacturers, and environmentalists. They have very poor aesthetic attributes (not really want you to need 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 aren’t only 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 astounding; in 3 years we must expect to determine LED light bulbs that are 40 times more effective. It is no surprise that the lighting business has en-masse elected to abandon CFL growth and focus on LEDs.
So should you be buying LED light bulbs at the moment? And since modern LEDs last over 50,000 hours (compared to 2,000 for regular light bulbs) the yield on investment just keeps rolling in.
Now some people will assert that it is sensible to wait until LEDs are both more economical and much more effective, but again if you run the mathematics you may 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, though they will still have years of life left. How so? Since the cost of electric lighting pretty much equates to the cost of electricity – it’s all in operating costs, not the hardware cost.
