Trying to confirm my thinking on the wattage conversion on fluorescent lights versus standard incandescent bulbs. Example - I have a 2-bulb porch light fixture that is rated for 60 watt bulbs (120 total). I have some fluorescent bulbs that pull 19 watts but are equivalent to a 75 watt incandescent bulbs. If I use these 2 fluorescent bulbs, I'm only pulling 38 watts, correct? I'm pretty sure I'm OK here, but I want to make sure I'm not overloading this fixture. Thanks
