Led Vs Fluorescent tube comparison
Fluorescent tube lights are the modern trend in lighting that is used for business purposes, offices, shops, and homes. However, you might be confused about the usage of fluorescent lights, what are the benefits, and what are uses. When it comes to LED vs Fluorescent tube lights, let us discuss the comparison between the two and their differences.
Fluorescent tube
Fluorescent tubes are available in different sizes and shapes. The most common is the T-8 size. The shape of the fluorescent tube is like a spiral.. The fluorescent tube lasts longer than an incandescent bulb. You can normally expect a fluorescent tube to last for six to twelve months with normal usage.
Led Lights
Led bulbs are not just an energy saver, but are also brighter and can last for a longer time. However, led bulbs are more expensive than fluorescent tubes. The shape of led bulbs is like a dome. Some led bulbs can be connected with dimmers and thus can be used in different kinds of ways.
How much less energy does a fluorescent bulb use?
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.
How long does in-rush last on fluorescent lights?
The "in-rush" of electrical current that occurs when you flick on a fluorescent light lasts 1/120th of a second, and uses about the same amount of electricity as a few seconds of normal light operation.
How much energy does a fluorescent tube use?
Originally Answered: how much energy does a tube light consume ? 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 lumens does a T8 bulb use?
One may also ask, how much energy does a 32 watt fluorescent bulb use? 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.
How much energy does a bulb save?
While the difference is only 236.52 kWh, keep in mind that this is for one bulb only! If the cost of energy is $0.11 per 1 kWh…with just one bulb the building would save approximately $26.00.
What is the advantage of LED tubes?
From the comparisons above, it is fairly clear that LED tubes hold the advantage as an overall lighting solution . Luminous efficacy is basically how well a light bulb produces visible light in comparison to the power consumed and the amount of lumens generated. Simply, it is how many lumens are produced per watt.
Can LED lights be improved?
The answer to the above question plain and simple: NO, not only will the light levels improve, but will maintain their brightness levels for the entire duration of the LED tube’s life. Which cannot be said the same for fluorescent tubes.
Do fluorescent lights flicker?
How often have you walked in an underground garage or down a hallway, only to notice the ominous light flickering. As fluorescent tubes expire, their light levels decrease significantly…and eventually they start to flicker. In comparison, LED tubes do not flicker or decrease the amount of light coming from the bulb. The light level always remain the same – as the tube reaches the end of its life, it simply stops working. No decrease in lighting, no flickering, and most importantly no creepy experience for your tenants!
How efficient are fluorescent lights?
Are Fluorescent lights energy efficient? Fluorescent tubes have traditionally been a source of efficient and effective lighting in homes, long before compact fluorescent and LED lights came along. They are most commonly found in kitchens, either in a long 'strip' form (three or four feet in length) and occasionally circular.
Why are fluorescent tubes not directional?
Because of the non-directional nature of the light, they ensure safe lighting. Fluorescent tubes last several years. If there are signs of flicker, or a tube has apparently failed, it may not be the tube that has failed. All that might be required is a replacement 'starter'.
Do fluorescent tubes use electricity?
An urban myth has continued to circulate about the amount of electricity used by fluorescent tubes when they are first turned on. The extra electricity used is negligible. If it wasn't, it would blow your fuses and trip switches.
How many bulbs are in a fixture?
They are sometimes used in manufacturing environments as direct lighting over a particular area.These fixtures have 4' bulbs and most have 3-4 bulbs per fixture. 8' - Long and narrow is the best description of these types of fixtures. Typically seen in 2 - 8' bulb configurations.
How many watts does a 100 fixture use?
100 fixtures x 158 Watts = 15,800 Total System Watts (Assuming this is the only type of fixture you have...)
What is a 2x2 bulb?
2' x 2' - Typically a square type of fixture. Found most often in office situations. This style fixture has a U-shape bulb.
Does General Electric use averages?
This way would require a tremendous amount of time and effort which isn't necessary since companies like General Electric and most utilities adopt averages for calculations.
