How many lumens are in a 32 watt t8 bult?
As much as your mother weighs
Which is hotter a fluorescent light tube or a light bulb?
By far the hottest of the two light sources is the light bulb.
How many lumens does an 18 watt CFL give off?
Currently maximum LED luminous efficiency is about 114 lumens/W, measured at 50mA. Average luminous efficiency is about 104 lumens/W. Ordinary LED light effect is about 60 lumens / W. 18W is about 130 lumens is about 1080 lumens.
Is a T8 ballast and T8 bulb more efficient then a T12 ballast and a T8 bulb?
In a T* ballast and T8 bulb more energy efficient then a T12 ballast and a T8 bulb? A:Depends on the CURRENT through the tube. When the Tube is run at 100% of rating, The T12 Takes more CURRENT to give a certain Brightness. Because the surface of the T8 is closer to the ion stream through the tube, it takes less CURRENT to light up the T8 to the same brightness. However, IF you use a T12 in a T8 ballast, you will get LESS CURRENT through the tube, and LESS POWER consumed ALONG with LESS Light.
How many lumen's are in a 36 watt T8 fluorescent tube?
2300lm Comment I think you mean lumens, not lumen's. No that answer is wrong Watts (energy usage) / Lumens (light output) 25 is equal to 200 35 is equal to 325 40 is equal to 450 60 is equal to 800 75 is equal to 1100 100 is equal to 1600 125 is equal to 2000 150 is equal to 2600 36 watts would be about 350 Lumens
How much area will a 2 tube 4' fluorescent light fixture cover?
Depends on how high it is off the floor. Make sure you buy a T8 and not a T12. The T8 puts out more light and will operate at a lower temperture. On a normal 8' ceiling a 2 bulb T8 will cover around 36 square feet of space. If the room is pretty large then an 8 foot 2 bulb HO light is a much better choice.
Can you replace t8 bulb in fixture now using t12 bulb?
Yes a T12 lamp socket will take a T8 tube. The T8 tube will not operate. The T8 ballast is an electronic ballast where as the T12 ballast is a magnetic type. If you are changing over fluorescent fixtures to the smaller T8 lamps then the ballast has to be changed and the end sockets have to be rewired. The schematic on how to do the rewire is on the electronic ballast's label.
Will a T8 fluorescent bulb work in a T12 fixture?
no
What is brighter 2000 lumen watt bulb or a 1500 lumen bulb?
This question is ill posed. Lumen is a unit of measure for how much light comes from the lamp Watt is a unit of measure for how much energy is used by the lamp If the question were; "Which is brighter, a 2000 lumen bulb or a 1500 lumen bulb?" then the answer would be: The 2000 lumen bulb. I think the relation ship between lumen and watt is something like: Incandecent bulbs are 15w/lumen Flourecent bulbs use 40w/lumen LED bulbs are 70w/lumen The way to show the watt and lumen relationship is usually lumens (amount of light) per watt (energy consumption). This is like gas in your car (Miles or KM per Gallon or Liter). Incandescent bulbs have a maximum luminosity of 52 lumens/watt. Fluorescent bulbs range from 46 lumens/watt (CFL) to 100 lumens/watt (T5 and T8 tubes) LED bulbs range from 29 lumens/watt (older, low efficiency) to 100+ (XCree) and they are getting better.
How many T8 fixtures can go on one 20 amp circuit?
Divide 20A by the Amps listed on the label of each fixture ballast. A T8 bulb will use an electronic ballast. They generally run 1A for four 4 foot bulbs. Try 15 four bulb fixtures per circuit and use a 20A rated switch.
How many lumen in a 600 mm T8 led tube?
Usually, t8 led tube with 600mm in dimension, the general power can reach up to 9-10w, in terms of light conversion efficiency of 100lm/w, which is commonly accepted today, 600mm t8 led tube could reach 900-1000lm.
Is a GE T7 bulb similar to a GE T8?
The "T" number indicates the number of 1/8th of an inch in diameter. A T7 would be 7/8" diameter, and T8 would be 8/8 or one inch in diameter. But from what I can tell, the length of the bulb is the big factor most people run into. Most incandescent T8 bulbs I find are 2.5 inches tall over all, and T7 bulbs appear to be 2.25-ish.
