How much wattage does a 250w HPS bulb use?
hps light averages 125 lumens, therefore, a 150 watt hps light is about 18,750 lumens.
How many lumens are in a 34 watt bulb?
The number of lumens produced by a 34 watt bulb depends on the type of bulb. As a general estimation, a standard incandescent bulb produces around 400-500 lumens per 40 watts, so a 34 watt bulb would likely produce slightly fewer lumens, around 350-450 lumens. However, different bulb technologies such as LED or CFL can produce a higher number of lumens with lower wattage.
How many lumens does a laser produce?
If you have the wattage of the laser you can plug it into a formula X/P=L. Where One lumen is equal to 0.001496 watts (1.496mW) which is Power. X is the number of watts or milliwatt and L is Lumens. So if you have a 1 watt laser you have 668.449 lumens being produced by it.
How many lumens per watt?
161 lumens I believe the above answer to be inaccurate. It depends on the light source. For example: For an incandescent light bulb 1 watt it is approx. 18 Lumens. However most LED's use only about 10% the wattage to produce the same amount of light. So for LED's .1 watt produces 18 Lumens.
What is the lumen output for a 35W halogen?
It varies from about 600 to 1100 lumens. Typically the higher the lumens output, the shorter the lifespan of the globe. Have a look at this list of globes for purchase whih shows wattage and lumens: http://1000bulbs.com/category/75-watt-incandescent-standard-shape-light-bulbs/
Do higher wattage bulbs give a brighter light?
No. All light from light bulbs (incandescent) are equally bright. Higher wattage bulbs simply produce a higher quantity of light measured in lumens.
What is the connection between wattage and bulb brightness?
Bulb brightness is measured in lumens which express the amount of light produced, while the electric power used is measured in watts. The typical efficiency of some different types of bulb is: Incandescent 12 lumens per watt Halogen 17 lumens per watt CFL (compact fluorescent) 50-60 lumens/watt LED (light-emitting diodes) 90-100 lumens/watt.
What is light strength?
It's a unit called lumens. You can look that up and find more about it. Or if you're I. The movie industry, it's measured in wattage. Hope this helps.
How many lumens are in a 300 watt incandescent light bulb?
The actual amount of light (lumens) given off by a bulb depends on the how the bulb was made and with what materials. It depends on the filament material, its length and thickness, and the type of gas in the bulb. As a rule, longer lasting bulbs of the same wattage will generally be less bright than others and brighter bulbs of the same wattage will not last as long as other bulbs.Sample lumen outputs:Sylvania 250 Watt Indoor Soft White 3-Way Bulb can emit 3940 lumens at its highest setting.Philips 250 Watt 120 to 130V PAR38 Krypton Flood Bulb emits 3100 lumens
How many lumen's does a 200 watt light bulb produce?
100 W tungsten incandescent (220 V): 1380 lm
What is equal to 60 watt in CFL?
If the question is what wattage compact fluorescent (CFL) lamp has a similar light output to an incandescent lamp of a given wattage, the ratio is usually about 4. A 60W incandescent can be replaced by an 13-15 W CFL lamp. A 60W CFL lamp can replace a 300W incandescent lamp.
Would the current of a light bulb be greater or less than when first turned on?
incandscent light bulbs voltage is 120 wattage is100 light output is 1560 lumens,use resistance as a function of temperature
