Dark winter

We specify on all our new projects LED lighting.

I have noticed the local authorities using LED luminaries on thier highway lighting systems and this depending on the efficacy i.e lumens per watt you do get the gains thus with a reduced current as opposed to discharge lighting i.e fluorescent luminaries

As you well know, I'm paraphrasing _v_ who I believe was advocating the murder of everyone else.

A thread about lightbulbs doesn't need any discussion of murdering IMHO If violence must be mentioned, let's talking about "knocking their lights out"

Well there's a thing:

Well, there's another thing.

Many (all? ) LED bulbs these days use all kinds of weird and wonderful trace elements. But there's a lot of materials science research underway to try and coax light out efficiently from common materials such as perovskites

Is that the same as organic LED research?

I'm not happy about the government banning the sale of halogen light bulbs.

In fact, I'm incandescent.

Here we go, if the Fail is right, we'll need white sticks & a nice labrador before long.

I didn't bother reading it, but I'm sure they give you cancer too.

basically its saying bright lights hurt your eyes. Car headlights are now brighter because leds allow that with less power.

The fashion for 100w equivalent led head lights with a focused lens attached on cars may blind you just like a laser. Especially if its on an antisocial tractor like a Range Rover and shines directly into your eyes.

If there's one thing I hate more than Range Rover and BMW drivers, it's Range Rover and BMW drivers with those bloody headlights that can practically blind you from a mile away.

I was, but I'm easily LED

Oddly enough, the enemy of semiconductors & electronic components, Specifically In General, capacitors, is heat.

Whilst the halogen spot is remarkably unconcerned that it's running at 150 deg C in the fitting, the electronic replacement gets very upset by this and dies.

Not helped by what passes as a heatsink being at the top of the device in that sort of fitting.

Much the same sort of thing kills CFLs in enclosed fittings.

Is it too late to patent a heat dissipating copper lampshade?
