Full Answer

Which is better, led or fluorescent T8 bulbs?

The following are 8 fact-based reasons you should consider direct replacement LED bulbs over T8. 1. LED replacement bulbs are 30% more efficient. Not only do you get more light from a LED replacement bulb; they also use less wattage. Our LED replacement bulbs only use 22 watts vs. 28-32 watts with T8, making the LED 30% more efficient. 2.

What is the lumen output of a T8 lamp?

It is also apparent that more RE80 models are available than RE70 or RE90 models, and their rated light output values vary over a much wider range. As illustrated by the data provided in Figure 1, T8 lamp models are available with light output values at almost every 50-lumen increment between 2800 lumens and 3200 lumens.

How many lumens is a 32 watt T8?

This Philips 24667-8 32-watt T8 linear fluorescent tube has 2,950 initial lumens and a color matched for halogen bulbs. Rated for 36,000 life hours, this T8 bulb is sold only by the case of 25. Brochures & Spec Sheets.

How many watts are in lumens?

Let's imagine that you are looking for an extremely bright bulb that emits 1,300 lumens. For an LED bulb, producing 1,300 lumens will require around 15 watts of power. However, for a less-efficient halogen bulb, over 60 watts of power are likely to be required to produce the same brightness.

How many lumens are T8 bulbs?

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.

How many watts is a 4ft T8 bulb?

The 4-foot option is designed to replace F32T8 lamps, does not run through a ballast, and operates at 18 watts to emit 1,800 lumens at a temperature of 3000 Kelvin.

Can you replace fluorescent T8 with LED?

Yes, you can replace fluorescent tubes with LED tubes or LED-integrated fixtures. If you just want to replace the bulbs, you can use plug-and-play, direct-wire, or hybrid LED tubes. Plug-and-play tubes are the easiest to install as they do not require any rewiring to the fixture.

Which T8 bulb is brightest?

Eiko 10468 LED26WT8-48-850-G8D. Eiko leads the way with the most powerful LED T8 lamp at 26W 3500 lumens. This is the highest-lumen direct-wire LED T8 by 300 lumens. Available in 4000K or 5000K color temp, these lamps bypass the ballast and wire direct (single-end wired only).

How many lumens is a 4ft fluorescent tube?

A: This product has 2600 lumens per 4 foot.

Are T8 LED bulbs worth it?

I did some quick research on T8 LED fluorescent tube replacement and discovered I could save at least $20, since I would no longer need to replace the ballast. Additionally, the LED tube light would be at least 50% more energy-efficient than the already-efficient fluorescents, which would save me money in the future.

Are LED brighter than fluorescent?

Fluorescent lights produce between 50 and 100 lumens per watt. By comparison, LEDs can produce roughly 130 lumens per watt. For example, a T5HO Commercial LED tube light uses only 25 watts to produce an output of 3334 lumens. In other words, LEDs require fewer watts to produce a brighter light.

Can you replace 4ft fluorescent with LED?

You have fluorescent troffers or strip fixtures already, and you're wondering if you can just pop LED tubes in them or if you'll need to change out the fixtures for something designed for LED. Good news: You can absolutely use LED tubes in your existing fixtures!

What is the LED equivalent of a 40 watt fluorescent tube?

Replace 40W fluorescent tubes by 18W 4ft led bulbs.

How many lumens is a T8 LED tube?

Median efficacy for LED T8s tested by CALiPER to date is 44 lumens per watt. The highest efficacy measured to date is approximately 70 lm/W. At that efficacy, an LED T8 producing equivalent light output to fluorescent would draw 38 watts, increasing total energy use.

How to tell if a bulb is T8 or T12?

This will tell you quite a bit about the current tube and indicate whether or not the bulb is a T8 or T12. If you do not see markings, the size or diameter of the tube will be the easiest way to tell the kind that you have installed. T8 tubes will be one inch in diam. and T12 will be 1 1/2 inch in diameter.

How to measure bulb size?

If the label is missing or illegible, you can measure the diameter to determine the size. The letter “T” will stand for tubular shape and the number will tell you the bulb diameter in eighths of an inch. T8 will have one-inch diameter, the T5 will have a 5/8 diameter, and a T12 will have 12/8 inch or 1.5 inch diameter. If T8 and T12 are using the same bi-pin base (G13 most commonly), then you can use the bulbs interchangeably using the same fixture just as long as you check the milliamp requirements for the ballast (if applicable).

What are the drawbacks of T12 magnetic ballasts?

The main drawback to these options is their higher up-front costs per unit. They are one of the highest of all the options. Also, since the ballast is in place still there are maintenance concerns as well. That is particularly critical with T12 magnetic applications when it is no longer possible to procure new ballasts.

How big is a T8 ballast?

T8 tubes will be one inch in diam. and T12 will be 1 1/2 inch in diameter. If you happen to have a tube that is relatively small in diameter, about 5/8 of an inch, it is a T5. Once you know exactly what kind of tube that you have installed, the key will then be to understand the kind of ballast.

What is LED tube?

LED tubes are often used with office lighting and warehouse applications and can be used in both indirect and parabolic light fixtures. They work well in areas that implement climate control and have standard heights for the ceiling, including storage areas, mechanic garages, and fabrication floors. Almost any LED tube is a great, energy efficient ...

What is type B ballast?

Also known as “Type-B”, the most commonly installed is the direct wire or ballast bypass option. Rather than building expensive circuitry within for the ballast to function, this option enables the ballast to be bypassed entirely by the user.

What does a lower Kelvin mean?

A lower Kelvin value will mean that the light output is going to be closer to an orange or “warm” or “soft” tint. “Cool” White normally references bulbs with a color rendering of about 4000k and are similar in color to clear metal halides.

How many lumens per watt?

Now that we understand watts and lumens, we can use both terms to come up with lumens per watt or “efficacy.” Sometimes the term “luminous efficacy” is used. This is a measure of how well a light source converts energy (watts) into light (lumens). The old technology of tungsten incandescent bulbs only had an efficacy of about 15 lumens/watt. LED technology typically produces 70-100 lumens/watt, which means LEDs are about 5-6 times more efficient at producing light than incandescent bulbs. Use this 5:1 or 6:1 ratio as a rough guide when selecting an LED bulb to replace an incandescent bulb.

How much energy does a 60 watt bulb use?

A 60-watt bulb consumes 60 watts of energy. Since we used 60-watt incandescent bulbs for so many years, we associated a certain level of brightness with 60 watts. But we can’t do that anymore, since modern LED technology produces more light while using fewer watts.

How many lumens does an LED bulb produce?

The old technology of tungsten incandescent bulbs only had an efficacy of about 15 lumens/watt; LED technology can produce about 60 lumens/watt. In other words, LEDs are about 4 times more efficient at producing light than incandescent bulbs.

What is lumens in LED light?

A lumen is a measure of visible light energy. The higher the lumens, the brighter the light. All lighting manufacturers are starting to tell us how many lumens are produced by each of their lighting products. We see these lumen numbers on the Lighting Facts labels found on all new LED bulb packages. It may take a while to get used to using lumens instead of watts, but it’s important in order to make the best lighting choices.

What is lumen in LED?

A lumen is a measure of visible light energy. More lumens equals a brighter light. All lighting manufacturers are starting to tell us how many lumens are produced for each of their lighting products. We see these lumen numbers on the Lighting Facts labels found on all new LED bulb packages.
