Just going back to the incandescent versus "CFL" here... - Am I wrong here, or did nobody mention the word "Lux" in that whole thread? Can anyone tell me the relationship between CFL and Incandescent light bulbs versus watts equals Lux?
In other words, for power input, how much light power (Lux) do you actually get? I also noticed a colour difference... Ironic for a colour blind lad :) Ying tong! On 04/04/07, Ben Jones <[EMAIL PROTECTED]> wrote:

I in hinesight prob should have not included the bit about Glazing pistons, thinking about it now... we on the mine site had a requirement to have a spinning reserve and 3 extra generators just ticking over idle ready ( introducing the glazing problem) for a demand alarm which the dweeb operators are ment to trip 10 mins before dropping the ball and sag mills online, but grunt knuckle dragging miners would not trip the demand alarm and drop both mills on line before i could get the idle gensets up to speed sync'd and on the buss and pull over the station, mine and town into complete darkness, only because the current protection on the station was 10 times more accurate than there old Rayroll Gear > >> And soon (ill bet my right nut on it ) power providers will >> force a move to digital power meters on you house, > > Don't know where you've been the last few years Ben, Never left the sparkie job yet . >but that's not > news.
