    Most of our globes are those curly ones but looking at pics on google they probably aren't LED. Garden lights would be the place to start. I'll have to buy one or two at a time because they're quite expensive.

    How does one move to this light option? I'm paying 1.90 or something per kW. Also using under 600 units a month.
    The Tarif is available to any one directly with Eskom
    It costs about R900 bucks to convert. There is a limit though on the amperage (60 or 80 not sure exactly) so if you have high power equipment you can't go on this tariff.
    If you check your slips when you buy electricity you will notice there's a network charge comes to about R3 a day (so +/- R90 a month) so you make back your R900 in 10 months
    Some times the internet is so slow, it would be faster to just fly to Google's headquarters and ask them this $h1t in person.!

    squigly ones are energy savers, use less then incandescent but LED is the way to go to save more.

    Ah, I suspected as much. Thanks for confirming.

    This depends whether you charger is all the time powering your laptop. It varies from 1 Ampere to 3 Ampere /18 Volt. with an efficiency of 84% gives you an average of (1,5 x 18 )/0.84 x 24 hours = 772 watts per day = per month 23 kwh or units. We pay R1.60 per kwh and that means R36,- having it on all the time. I normally remove the charger after use, which saves me about 20 Rand per laptop ( I have 3 running). Trust that this helps you. I like to live in the area which charges 40.1 cents/kwh instead of 1,60. I think the calculations are some 20 years old with 40.1 cents /kwh Bert
