Many years ago, when the only fluorescent lights were the long tube type, I read that fluorescent lights use a lot of energy getting lit up, and hardly any once they’re lit. Supposedly it used less electricity to leave the light lit than to shut it off and turn it back on, unless you were going to leave it off for several hours. Is this correct? And if it’s true of fluorescent tubes, is it also true of the new compact fluorescent bulbs?

the question is,
compare the lifetime electricity costs of a compact fluorescent light bulb to an incandescent light bulb using the data in table 1
the information in the table is
60-watt incandescent
initial cost $0.50
life of bulb (hours) 1000
replacement cost 5 x $0.50
lifetime electricity rate $0.08/kWh
lifetime electricity cost ?

15-watt fluorescent
initial cost $7.00
life of bulb (hours) 10000
replacement cost -
lifetime electricity rate 0.08/kWh
lifetime electricity cost ?
how would i do this problem? please help! thanks in advance!

so i dont have a thermometer to check the actual temperature of my bearded dragons lights.
her basking light is in a mini deep dome lamp fixture with a repti basking spot lamp it is laying directly on top of her tank
then her uvb light is in a deep dome lamp fixture with a 10.0 compact fluorescent bulb in it and it is also laying on top of the tank.
her tank is 10 long..
can someone like extimate to me what the temperatures for those may be?
my beardie is 5 months old ive started turning her lights on at 6 am and then turning them off at 6pm
well see the problem is she is no where near ten inches she is about 4 or 5 inches..
her tail was bitten off though so that makes her smaller but now im worried she isnt big enough!
ive only had her two days and she seems to enjoy the lighting she never tries to hide from it like its too hot and she seems extremely happy. i turn her lights on at 7 am feed her roughly 5-7 crickets then set out a salad which is always different leaves and veggies (except i always give her romaine cause she loves the stuff!) give her a bath around 4, handle her for about 3-5 minutes 3-5 times a day and then at 7 pm i feed her 5-7 more crickets turn her lights off and do the same the next day. i hope im not doing anything wrong ):

I recently received an 8 year old Bonsai tree that I am keeping by the window in my apartment. I am worried that there is not enough light coming through the window to meet my plant’s needs.

Until I have the funds to purchase an actual grow light here is a list of the lights that I have that I can put on it in addition to the natural light coming in through the window. (note: I realize all of these are very poor options but something is probably better then nothing at all)

20W MR11 (which is halogen I think) table light
35W GY6.35 Lamp (also halogen I think) table light
BR0807/E17 7W Compact fluorescent (Ikea room light)
a couple LED night lights
Artograph lightpad (many LED based light pad)

also, is there a grow light bulb I can purchase later on that will fit in 1 of the first 2 fixtures I listed?

THANKS in advance!

because they’re more energy efficient.

I’m trying to find replacement Compact Fluorescent bulbs for a light fixture and am finding plenty of CFLs with GX24q-1 base but the bulb I removed from the fixture is labeled G24q-1. What is the difference between the two and are they interchangeable?
