4ft T5 Grow Light Bulbs – If you haven’t given the field of lighting much idea recently that’s likely because, in common with most folk, the phasing out of conventional incandescent light bulbs has not been exactly uppermost in thoughts. That is not all that surprising; being able to switch the lights at will hardly appears to be a big deal. We do it all the time and as priorities go the entire company of light is off the radar. Yet the passing of the incandescent light bulb proceeds quietly yet relentlessly and in less than a couple of years now the sole products carried on shelves will probably be low energy light bulbs, where there are two kinds: CFLs (Compact Fluorescent Lamps) and LEDs (Light Emitting Diodes).
Presently, the majority of low energy light bulbs accessible are CFLs which are a few 4 times more efficient than incandescent bulbs (i.e. they only waste about 25% of the energy as heat, in comparison to 90%). But, CFLs are commonly disliked by customers, manufacturers, and environmentalists. They have quite poor aesthetic qualities (not actually want you to want for light), they’re awkward to eliminate safely as a result of their mercury content, and they’re complex and costly to manufacture.
LEDs on the other hand score well on all these points and a few more besides, the most obvious of which is that LEDs are not only 10 times more efficient than incandescents at present, however they double in performance every 18 months or so. |} The consequences of this (called Haitz’s Law) are astonishing; in 3 years we must expect to see LED light bulbs which are 40 times more efficient. It is no surprise that the lighting business has en-masse chosen to abandon CFL development and concentrate on LEDs.
So should you be buying LED light bulbs right now? And since contemporary LEDs continue over 50,000 hours (compared to 2,000 for routine light bulbs) the return on investment just keeps rolling.
Today some folk will argue that it makes sense to wait till LEDs are both more economical and even more efficient, but again in the event that you run the math you will find that in fact, it’s better to replace perfectly usable light bulbs with LEDs today and then plan to replace them in a few decades, though they will still have decades of life. How so? Since the price of electrical lighting pretty much equates to the price of power – it is all in managing costs, not the hardware price.
