What is easier to install an incandescent light bulb or a fluorescent light bulb?

It depends. If you have a compact fluorescent bulb, it is about the same difficulty level as installing an incandescent bulb. If however you are installing a 4 foot long fluorescent tube, it may be considered a bit more difficult because there are 2 pins on each end of the tube that have to line up on each end of the light fixture, thus it would require a bit more effort and coordination. Once you line the end pins up, you push the tube into the slot until it is fully seated, then you give it a quarter turn to lock it in place.


How many watts does a HO 8 foot T-12 fluorescent lamp fixture draw?

Look on the ballast inside of the fixture. There is an amperage and a voltage on the ballast label. Use this equation to find the wattage. W = I x E, Watts = Amps x Volts. This will give you the answer that you are looking for.


How many marijuanna plants can you grow with 250 watts of light?

Long answer: it depends what kind of bulbs you're using, how big your plant is, how you have the light spaced, etc. 250 watts= 5, 50 watt incandescent bulbs; 6, 40 watt, 4-foot fluorescent bulbs; two 125 watt metal halide or high pressure sodium bulbs. If you can afford the HPNa or the MH, you can afford more wattage. If you're strictly limited, I would recommend 3, 4-foot, dual bulb fluorescent shoplights with alternating "daylight" and "plant/aquarium" bulbs. That should cost you about $20 per fixture, and $4-5 per bulb, for a total cost of $90 to grow an ounce of pot. Or you could buy a quarter of some good stuff and forget the effort, time, space, and risk. Short answer: One.


How many amps in a 40 watt light bulb?

A lumen is the perceived intensity of the light, as seen by the human eye. The lumen value is largely determined by the the nature of the light, i.e. the sum of the different wavelengths of the light being transmitted by the particular bulb type.The standard tungsten wire-filament ('incandescent') bulb radiates a different type of light to a flourescentlight.* a 230 V, 40 watt incandescent bulb produces a light (quality) of about 400-500 lumens,* a standard 230 V flourescent lamp of only 7 watts will produce exactly the same value of lumens, i.e. 400-500 lumens. * the cool white XLamp XP-G 3.5 V LED lamp of only 3 watts will produce a similar value of lumens, i.e. 350 lumens. And is safer for the workers that make them and better for the environment. It is currently more expensive, but prices have been dropping about 20% per year. Therefore LED light bulbs convert electricity into light more efficiently than incandescent or florescent light bulbs. * For more information, See Related links below this box


How many amps fluorescent bulb?

When you buy the bulb. All of those specifications should be on the package. To figure the Kilowatts it's pulling and cost to run. kW = amps x volts / 1000. then just take your kW x price per kw. and that will give you how much it costs to run that bulb for one hour. The amperage is on the label of the ballast. When you connect the ballast to power you will see it along with the voltage and pf of the ballast. F40T12 twin 8 foot tubes, ballast usually draws about .75 amps.

How do you grow broad leaf sage indoors?

Sage will grow indoors satisfactorily under standard fluorescent lamps, and exceptionally well under high output fluorescent , compact fluorescent, or high intensity discharge (metal halide or high pressure sodium) plant growing lights. Keep standard fluorescent lamps between 2 and 4 inches from the tops of the plants, high output and compact fluorescents approximately one foot above the plants, and HID lights between 2 and 4 feet above the plants, depending on wattage. Have an oscillating fan gently stir seedlings for at least 2 hours per day to stimulate shorter, sturdier, and more natural plant habit.
