The Most Energy Saving Light Bulbs – In case you haven’t given the field of lighting much idea recently that’s probably because, in common with most folk, the phasing out of traditional incandescent light bulbs has not been exactly uppermost in your thoughts. Which isn’t all that surprising; being able to change the lights at will hardly appears to be a major deal. We do it all the time and as priorities go the whole business of light is comfortably off the radar. However the passing of the incandescent light bulb continues quietly yet relentlessly and in under a couple of years now the only products stocked on shelves will likely be low energy light bulbs, of which there are two types: CFLs (Compact Fluorescent Lamps) and LEDs (Light Emitting Diodes).
Presently, nearly all low energy light bulbs available are CFLs which are a few four times more efficient than incandescent bulbs (i.e. they just waste about 25% of the energy as heating, in comparison to 90%). But, CFLs are widely disliked by consumers, manufacturers, and environmentalists. They have quite poor aesthetic attributes (not actually want you to need for light), they are awkward to eliminate safely thanks to their mercury content, and they are complex and expensive to fabricate.
LEDs on the other hand score well on all these points and quite a few more besides, the most evident of which is that LEDs aren’t just 10 times more efficient than incandescents at current, however they double in performance every 18 months or so. |} The consequences of this (known as Haitz’s Law) are astounding; in 3 years we must expect to see LED light bulbs that are 40 times more efficient. It is no wonder that the lighting industry has en-masse chosen to abandon CFL development and concentrate on LEDs.
So if you be buying LED light bulbs right now? And since modern LEDs last over 50,000 hours (compared to 2,000 for routine light bulbs) the yield on investment just keeps rolling in.
Today some folk will assert that it makes sense to wait until LEDs are both more economical and much more efficient, but in the event that you run the math you may find that in actuality, it’s better to substitute perfectly usable light bulbs with LEDs today and then aim to replace them in a few years, though they will still have years of life left. How so? Because the cost of electrical lighting pretty much equates to the cost of power – it’s all in managing costs, not the hardware cost.
