A T8 fluorescent that uses 32 watts of energy typically produces 2500 lumens of light. It's LED equivalent, while using only 17 watts, produces 2200 lumens. Additionally, T8 LED light bulbs have a lifetime rating of 50,000 hours, more than 3 times longer than 15,000 hour average lifespan of T8 fluorescent lights.

Just so, how much power does a t8 ballast use?

They consume eight to 10 watts when operating with the lamp in the circuit. The ballast will consume about four watts when the lamps are removed although the ballast is still energized.

Additionally, do fluorescent tubes use a lot of electricity? Fluorescent lamps, including compact fluorescent lights (CFLs), use about 75 percent less energy than incandescent bulbs and last six to 15 times as long, according to the U.S. Department of Energy (DOE). But it's widely believed that these popular bulbs use a lot of energy to start up. Otherwise, turn the light off.

Keeping this in consideration, how much power do fluorescent lights use?

A typical fluorescent tube is about 40W with ballast. Energy is power over time. If you operate for 1000 hours, then, you consumes 40 kWh.

How many watts is a 4 foot fluorescent bulb?

The two most common types are 40-watt, 4-foot (1.2-meter) lamps, and 75-watt, 8-foot (2.4-meter) lamps. Now, tubular fluorescent technology has improved. New products such as T8 and T5 are much more energy efficiency than T12 (T12 – 57 lumens/watt; T8 – 92 lumens/watt; T5 – 103 lumens/watt).

Do I need to remove the ballast to use an LED bulb?

LED technology does not require a ballast to regulate the amount of energy flowing to the lights. Additionally, removing the ballast will reduce energy usage and result in even great cost-savings as ballasts continue to draw more power than necessary.

How many amps does a ballast draw?

A 1000 watt light draws about 9.2 amps at 120 volts (1100 watts / 120 volts = 9.17 amps). See this page for other ballast wattages.

How much energy does a 40 watt fluorescent bulb use?

What Uses Watts in Your Home
Appliance/Equipment Avg. Usage Monthly kWh
Lighting
40-Watt Bulb (40 W) Equivalent compact fluorescent 4 hours/day 4 hours/day 5 1.375
60-Watt Bulb (60 W) Equivalent compact fluorescent 4 hours/day 4 hours/day 7 1.625
75-Watt Bulb (75 W) Equivalent compact fluorescent 4 hours/day 4 hours/day 9 2.5

Are LED lights better than fluorescent?

Both types of lighting are energy-efficient when compared to traditional incandescent bulbs. LED technology costs more than CFL and fluorescent lighting, but the LED bulbs also last longer and use less energy than fluorescent bulbs. LEDs do not contain mercury or harmful gases.

How much does a ballast cost?


A replacement ballast costs about $10-25 depending on capacity and brand. The bite is that an electrician trip charge (which includes 30 or 60 minutes work) is going to be $75-150 probably - for about 5 minutes work on each light fixture.

How do I know if my ballast is t8 or t12?

This will reveal a lot about your current fluorescent tube and usually indicate if the bulb is T8 or T12. If no markings are available, the size in diameter of the tube is the easiest way to determine the type you have installed. T8 tubes are 1-inch in diameter and T12 tubes are 1 1/2 -inch.

Are t8 bulbs energy efficient?

The smaller the lamps the more energy efficient they are. T8 bulbs use about 35% less electricity to produce the same amount of light as a T12. T5 bulbs use about 45% less energy than T12s.

Can fluorescent tubes be replaced with LEDs?

Yes, you can replace fluorescent tubes with LED tubes or LED integrated fixtures. If you aren't ready to replace the fluorescent fixture and just want to replace the bulbs, you can use plug-and-play, direct wire, or hybrid LED tubes.

How much electricity does a 15 watt bulb use?

If you were to run that 15W bulb continuously, 24 hours a day, for 30 days (a month), it would consume . 015 kW * 24 * 30 = 10.8 kWh. At 7.46 cents/kWh, that would cost you about $0.81 per month.

Are strip lights expensive to run?


Lower running costs
The most obvious benefit from fluorescent strip lights is the efficient use of power. Fluorescent lights use less energy in the first place, which means reduced running costs.

How many amps does a 4 foot fluorescent light draw?

Re: T8 Florescent Filxture Amp Draw
I see them anywhere from 49 watts to 86 watts. With 4 bulbs in each fixture, that is anywhere from 196 watts to 344 watts total. So @120v Anyhwere from 1.6 Amps to 2.9 Amps per fixture depending on the bulbs you used.

Is it cheaper to leave fluorescent tube lights on?

You may have heard people say: “It's best to leave fluorescent lights on: it's cheaper than switching them on and off”. It is true that switching on/off fluorescents reduces lamp life but lamps are designed to be switched on/off up to seven times a day without any effect on their life.

Are LED lights better for your eyes than fluorescent?

LED Bulbs: These are the most energy efficient bulbs, but they cost the most up front. They produce no UV rays. There are many myths regarding LED bulbs. Compact Fluorescent Lights (CFLs): CFL bulbs produce fewer UV rays and are more energy efficient than bright white incandescent and fluorescent tube bulbs.

How long is a kilowatt hour in real time?

A kilowatt-hour is 1,000 watts of electricity used for one hour.

How many kWh does a TV use?


How much electricity does my television use? Most TV's use about 80 to 400 watts, depending on the size and technology. Using a sample cost of 15¢ per kilowatt-hour and five hours of viewing a day, that's $1.83 to $9.13/mo.

Do burned out bulbs use electricity?

One incandescent light bulb makes light by heating a metal filament wire to a high temperature until it glows. If the lightbulb burn out, the filament breaks and the electrical current is zero because the air works as insulation and "switch off the lightbulb". The electricity consumption is also zero.

Is it safe to leave fluorescent lights on all the time?

Turning off fluorescent lights saves more energy than leaving them on all of the time. In fact, the Electric Power Research Institute debunked the notion with a study that revealed it only makes sense to leave the lights on if someone is only leaving the room for three to five minutes.
