    I have just completed the lighting at Williams Hunt Port Elizabeth and am busy at Chev. 100W LEDs, now light up the place at night. Mercury Vapours have mostly been replaced with 85W CFLs'. Those above the hoists, with 200W. All 8' flourescent fittings have been removed. 5 & 4' Phillips are the replacement. 5 & 4' lamps have also been replaced in existing fittings. This will bring about a huge saving. Problem with the lamps though is the poor quality. I have had to exchange boxes full because they do not work. There have been a lot which did not last 2 weeks before blowing too. The fluorescent tubes are not too bad, about 20 duds out of 600+. The CFLs' however are a pain, about 15% duds. No problems getting them exchanged but a lot of time lost

  2. Thanks given for this post:

    and to replace any 400 highbay fittings where people want to save money.

    when i had the fitting on the ground i took it and lit up across the factory and all i can say is wow...one of the contractors who i know have just installed a whole warehouse full of these fittings the problem was the height 13 + metres and i am told they worked out perfectly...i will take a look as soon as i can get a gap.
    They are obviously the High Output tubes. You can install them with or without wings(reflector). I put them in the "inspection" area at Chev where they need very good light with the "wings" and at the new fitment centre without the "wings". The reflector makes a huge difference too. They are also available in 54W which is 4' as opposed to the 5' 80W.

    Reduce your electricity account by skipping the washing machine's pre-wash cycle if your clothes are not particularly dirty. This will use up to 20% less electricity. You can also use one large light bulb instead of a few small ones. One 100-watt light bulb uses less energy and gives off more light than two 60-watt bulb light.

    Rather use an LED lamp, the savings can be as high as 90%, depending on the application.

    Taking the Eskom rebate into consideration when getting rid of 50W downlighters, high wattage fluorescent, Mercury Vapour, and Metal Halide lamps does help to bring the cost down.

    The Eskom rebate on Heat-pumps and Solar geysers will apparently cease at the end of March 2013, I am not sure about the rebate on lighting yet.

    Cant wait for the rebates to end, maybe then the prices will become more realistic for the general public.

    Refrigerator and freezer doors should seal tightly. Loose seals cause your unit to work harder and use more energy.

    In my private apartment I changed following things:

    I now use energy-saving lamps
    I now have a laptop instead of a PC
    All my electrical appliances are in remote controlled electrical sockets, so I can switch them off togehter, when I go sleeping
    The radiators are not covered
    I shower more than that I bathe
    All my water connections have a limit on water flow
    I use the microwave when it is useful and I use the stove when it is useful.
    You also save more energy using a dishwasher, instead of doing it by hands.

    and so on..

    Guten Abend

    I hope all is well in Germania

    I have a question for you..
    What is your best “declassified” output spec for small solar panels?
