Uv Light Bulbs Bunnings – If 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 hasn’t been precisely uppermost on mind. That is not really all that surprising; being able to change the lights on at will hardly appears to be a major deal. We all do it all the time and as priorities go the whole company of lighting is off the radar.
Presently, the majority of low energy light bulbs available are CFLs which are some 4 times more efficient than incandescent bulbs (i.e. they only waste about 25 percent of their energy as heating, compared to 90 percent). But, CFLs are commonly disliked by consumers, producers, and environmentalists. They have quite poor aesthetic attributes (not actually 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, however they double in performance every 18 months or so. |} The implications of this (known as Haitz’s Law) are astounding; in 3 years we should expect to see LED light bulbs which are 40 times more effective. It is no wonder that the lighting industry has en-masse chosen to abandon CFL growth and concentrate on LEDs.
So should you be buying LED light bulbs right now? And since modern 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 makes sense to wait until LEDs are both cheaper and much more effective, but again if you run the math you will discover that in actuality, it’s better to replace perfectly usable light bulbs with LEDs now and then aim to replace them at a few decades, though they will still have decades of life. How so? Because the cost of electrical lighting pretty much equates to the cost of electricity – it’s all in managing costs, not the hardware cost.
