    I recently replaced two dual tube fluros (round type) in our family room with two led lights. Surprising how hot the ballasts got, they would burn your fingers if you touched them. I wonder how much power I used just heating them

    I recently replaced the six double fluros in our office to LED type fluros.

    Current draw went from 2.49amps to .39amps for all six.

    And they switch on immediately,no delay when they start.

    Wouldn't mind solar at our place but we have the tree issue,lots of shade.

    Typically 20w for the ballast for a double fluro is a rule of thumb. So from 100w down to 36w or so.

    All our house is LED.
    Workshop is also LED...

    Fitted draft excluders and draft sealing materials to every window or door opening, Inverter AC in each main room (so we can shut down and close areas, or in case of bedrooms only power up 15min before going in and using timer off).

    Energy efficient appliances where possible...

    We consume less than half the power (avg) than we did pre-solar,, which is what triggered the LED upgrades etc...

    For those who are still unsure, here's a solar Calculator.

    It can be set for various capitol cities.

    At the moment, it's showing my 4kW system as supposedly producing 1.4kW...
    - In fact due to clouds, the real figure is varying between 820W and 1220 watts.- close enough to work with, IMHO

    My alignment is 2 strings optimized for "AM" sun, and the 3rd string favours after midday... but should be lifted up on a frame for better production. (Cost tooo much!)
