Are T8 bulbs being discontinued?
Are T8 bulbs being discontinued?
Even some T8 lamps have been phased out. US Congress has enacted legislation to prohibit the manufacture of these and other inefficient lighting technologies, and is calling for manufacturers to meet minimum efficiency requirements and lumens per watt for new products.
What wattage do T8 bulbs come in?
32 Watts
A common T8 bulb is the F32T8 which uses 32 Watts of power. The wattage for LED tube lights varies depending on light output as well. Tube lights under 1800 Lumens require fewer Watts than T8 lamps that product over 2000 Lumens.
Which T8 bulb is brightest?
The brightest four foot T8-sized LED tube light is the Barrina LED Shop Light Fixture. This tube shines with 5000 lumens using 44 watts. It replaces a 72 watt fluorescent tube.
Are all T8 bulbs the same?
Like T12 lamps, T8 lamps are available in a variety of color temperatures, including warm (3000 K), neutral (3500 K), cool (4100 K), and very cool (5000 K). Color temperature may also be included in the designation by replac- ing the zero in the new designation with the first two digits of the CCT.
Which is better T8 or T5?
If you do not need as many lumens, the lesser wattage T8 would be the better choice since it offers lower lumen and watt consumption. If you need higher levels of lighting, the T5 might be ideal for your situation.
How many Watts Does a T8 light 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. Simply so, how many watts does a 4 ft fluorescent light use? They operate the lamps at the nominal 430 ma. and allow the lamps to produce greater than 92.5% of rated lumens.
What is the light output of T8 fluorescent lamps?
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.
What is the life of T8 fluorescent lamps?
Lifespan- The average life of a T8 Linear Fluorescent Lamp is 30,000 hours, while a T8 LED will last 50,000 hours. That said there are newer linear fluorescent T8 lamps that can last up to 84,000 hours.
What is the wattage of a 4 lamp T8 fixture?
T8 lamps also vary in size and associated wattages. Lamps for a 4 foot light fixture range from 24 or 26 watt reduced energy bulb to 32 watt standard output. Lumen output is controlled by the ballast.
