I have finally exhausted my supply of incandescent light bulbs and thus decided to buy an LED corncob light. I live in Canada and for the majority of the year, the heat from a light bulb is not wasted. In addition, when the heat of a light bulb would be wasted — in the summer — light bulbs are used less as our days are long.
It could be said that I’m not a fan of fluorescent light bulbs. It’s not just the years I spent in educational institutions under their light. It’s not just that they cause computer monitors to appear to flicker (although that effect is nearly gone with new technology). Mainly, it’s that I don’t like the light they give.
So being bereft of incandescent bulbs that I prefer, I ordered an LED bulb from e‑bay to try. It was one of the ones called a “corncob” and was advertised to be equivalent to 60 watts of incandescent light. In the e‑bay item description, this particular seller actually advertised 800 to 1000 lumens — which is more than a 60 watt light bulb but less than a 100 watt light bulb.
On the right here, we can see the effect of the two bulbs installed in my office ceiling fixture. The bulb on the left-back is a 60 watt compact fluorescent equivalent and the bulb on the right-front is the 12 watt 800 to 1000 lumen (advertised) LED.
The LED is much dimmer. The room is obviously dim while lit by only the LED. I’m a little worried about the build quality of the LED, too. A few posts on u‑tube worry me more. I’m not going to leave it in there.
Some research leads me to wonder about LED light — mainly that most LED lights emit one specific frequency well and that “white” LED’s are a hack. I’m not sure if I want to attempt ordering another cheap LED, but I was willing to loose my money on this one — and it seems I did.
