Re: Light Bulbs
I have recently changed to the Led bulbs after having a lot of problems with the long curly energy savings ones.Re: Light Bulbs
Given the apparent rise in cases of SAD, it would make sense for more lightbulbs which lux out the relevant thingies (for want of a better term)to be used as a matter of course, rather than having to purchase "daylight lamps"Re: Light Bulbs
Re: Light Bulbs
What I don't get is that when pocket calculators first came into mass usage back in circa 1980, the displays were LED. As indeed were many little lights that indicated whether something was "on" or not. How come it's taken all this time to work out that LED's can produce cheap and efficient lighting?
