Is this Ok?

What rubbish, the earth has cooled and warmed in cycles long before we generated our first Watt or hacked our first lump of coal from the ground!

I was making the point that these renewable floods are simply not up to the job yet, you'll be defending wind turbines next!

I'll stick with the science on this one, I run an electrical business, not a mass deforestation enterprise so i'm not offended, everything's cool (despite the global warming).

I was just quoting the building regs:

"External lighting fixed to an external surface of the dwelling and supplied from the dwelling (eg the consumer unit) must either be:

a) automatically controlled to switch off in daylight (photoelectric control) and switch off when not required (people not detected), and have a maximum lamp capacity of 150W, or

b) energy efficient."

Whether or not some bunny hugger decides that having a 150W floodlight on all the time is bad for the planet is a different argument.
As mentioned at present LED floodlights are on the expensive side of things and from what I've seen stand-alone floodlights with integral pv cell and storage battery are unlikely to provide enough light - you'd be better off saving the planet by fitting a pv array to your roof and buying the electricity back off the grid when you need it.
... Or of course there are CFL floodlights.

Again, whether the entire carbon footprint including manufacture of so-called 'energy efficient' lighting products is actually less than with traditional fittings is a different debate.
