Compact Fluorescent Plant Grow Light Bulbs – 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 conventional incandescent light bulbs has not been exactly uppermost on thoughts. That is not really all that surprising; having the ability to change the lights on at will hardly appears to be a big deal. We all do it all of the time and as priorities move the whole business of light is off the radar. Yet the demise of the incandescent light bulb proceeds quietly yet relentlessly and in less than a few years now the only products carried on shelves will probably 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 some four times more efficient than incandescent bulbs (i.e. they just waste about 25% of the energy as heat, in comparison to 90%). However, CFLs are commonly disliked by consumers, producers, and environmentalists. They have very poor aesthetic attributes (not actually want you to want for light), they’re awkward to dispose of safely thanks to their mercury content, and they’re complicated and expensive to manufacture.
LEDs on the other hand score well on all these points and quite a few more besides, the most obvious of which is that LEDs are not just 10 times more effective than incandescents at present, but they double in performance every 18 months or so. |} The consequences of this (known as Haitz’s Law) are astounding; in 3 years we should expect to determine LED light bulbs which are 40 times more effective. It is no wonder that the lighting industry has en-masse chosen to abandon CFL development and focus on LEDs.
So should you be purchasing LED light bulbs right now? 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 are able to do the math and realize that the savings in power consumption will more than repay the investment within the first couple of years. 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.
Today some folk will assert that it makes sense to wait till LEDs are both cheaper and even more effective, but again in the event that you run the mathematics you will find that in fact, it’s better to substitute perfectly usable light bulbs with LEDs now and then aim to replace them in a couple of years, though they will still have years of life. How so? Since the cost of electrical lighting pretty much equates to the cost of power – it’s all in managing costs, not the hardware cost.
