Just don't turn the lights off and you will save on bulbs.

When I was living in South Africa I had a water heater in the cottage that I rented. It was called "Geyser", mounted in attic, and the whole thing was well insulated by fiberglass blanket and foil. I think it is more effective than banning of incandescent bulbs. Also, properly made double glass windows would help as well. Here in California I often see very mediocre insulation of houses, and even powerful fans running on attics because lack of insulation causes heating of ceilings by sun radiation, so air conditioners during days consume more power than probably all incandescent bulbs during the year.

Not surprising since Afrikaans is closely related to Dutch. Quote:

This of course creates it's own problems with mold and such if you don't ventilate properly. I'm sure the Norwegians or other Scandinavian countries have even better insulation. |

The best insulation I saw in traditional Siberian houses. Organic wooden logs about 30 CM thick, and double windows, 20 cm between glass layers.

Some of the best tight and insulated homes here are ... ready.... mobile homes. The Kirkwood I had in Colarado had full 6" walls, tight enough the front door would bounce. I had to leave a window open for fresh air. 1600 sq ft and heated it with a 35,000 BTU furnace. No problem at -20F. Our building codes here are pathetic. We build Mc-Mansions of 8000 sq ft 5 feet apart that will fall down in 20 years. Plywood foundations, cardboard or OSB sheathing. 12 inches of attic insulation in Phoenix where it takes two air conditioners because of the bad design. Then run fans in the attic because they were too cheap to put in proper soffit and ridge vents. Should we know better? Just visit Thomas Jefferson's home in Va. Cool tubes and copula for solar powered air conditioning. 1700's!

Cool tubes are a great idea for those who have the space.
Modern day tech could sanitize the air, possibly with UV or a forced air carbon filter. |

I bought, until now, 4 of these, 2 yesterday, and they are WARM white - not bright - or the yellow living room more than the white for the kitchen type. For this you have to look at Kelvins also (3500 vs 5000). They usually have the sign saying bright white vs warm white (yellow) for the same white (W) led lamp. OSRAM PARATHOM LED P1635GU10WW 1x5W GU10 Osram LED bulb PAR16 5W GU10 WW | 230 V LED Lights, GU10 LED Bulbs Light bulbs Lighting Home & Garden | Conrad Electronic SE - 230 V LED Lights, GU10 (the price is at 22,00 € in my country right now) You can read with the direct light of this lamp (like in sofa/bed) and it is enough (2 of them) for a living room. Also 2 of them at bed (one on each side) to watch TV or read. They are the 35 angle type vs the 110+ for the modest fluorescent old style lamps. All the information is on the box like Kelvins/Candelas/W/angle and so on. Also time to light up at max. is 0 sec. This is not to be tech info, just informative. They also sell good 70W type (max. I found) halogen bulbs/incandescent at IKEA. Last edited by Inductor; 8th February 2012 at 04:05 PM.

I guess my hoard of cheap 100W bulbs will go back in storage for a rainy day when I actually need that much light. Dollar or so a box is not too much of a burden for a small hoard! My gran had an ancient bulb she used at the sewing machine for illumination when I was a kid. It was something with a nipple on the top and the filiment was a big coil loopty thing. It had to be very ancient even then. Never burned out. I don't recall if it was tungsten or what. I wish I had it now. Bet it would be more than 80 years old, at least.
