Twisted Frosted Candle Light Bulbs 40w – If you haven’t given the field of lighting much thought recently that’s likely because, in common with the majority of folk, the phasing out of traditional incandescent light bulbs hasn’t been exactly uppermost in mind. Which is not all that surprising; being able to switch the lights on at will hardly appears to be a big deal. We all do it all of the time and as priorities go the entire company of light is off the radar. However the passing of the incandescent light bulb proceeds quietly yet relentlessly and in less than a couple of years now the only products carried on shelves will likely be low energy light bulbs, of which there are two kinds: CFLs (Compact Fluorescent Lamps) and LEDs (Light Emitting Diodes).
Presently, the majority of low energy light bulbs available are CFLs which are a few 4 times more efficient than incandescent bulbs (i.e. they only waste about 25 percent of the energy as heating, compared to 90 percent). However, CFLs are widely disliked by customers, producers, and environmentalists. They have very poor aesthetic qualities (not actually want you to need for light), 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 evident of which is that LEDs aren’t only 10 times more effective than incandescents at present, however they double in performance every 18 months or so. |} The consequences of this (called Haitz’s Law) are astounding; in 3 years we should expect to see 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 purchasing LED light bulbs right now? And since contemporary LEDs continue over 50,000 hours (compared to 2,000 for regular light bulbs) the return on investment only keeps rolling in.
Today some folk will assert that it makes sense to wait till LEDs are both more economical and even more effective, but if you run the math you will find that in actuality, it’s far better to replace perfectly functional light bulbs with LEDs today and then aim to replace them in a couple of decades, though they will still have decades of life. How so? Because the cost of electrical lighting pretty much equates to the cost of power – it is all in managing costs, not the hardware cost.
