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.

How many lumens does a 42 watt CFL give off?
a 42 watt cfl give off 2800 lumens
How many lumens in a 125 watt CFL?
Depending on the brand, it will give about 18.000 Lumens and equals a 100W HPS lamp
How many lumens does a 150 watt CFL give off?
A 150-watt light bulb uses energy at the rate of 150 watts, when it's turned on.
What is the lumen of 23 watt CFL?
A 23 watt cfl will give off roughly 1600 lumens. However that is only within a few inches of the bulb.
What is the percentage of light output between CFL bulbs and an incandescent bulb?
Incandescent: 10-12 lumens per watt CFL: 50 lumens per watt.
How many lumens are in a 60 watt incandescent grow light?
It's about 600 lumens. The same brightness comes from a 12 Watt compact fluorescent light (CFL).
Why cfl is widely used nowadays?
Compact fluorescent bulbs are widely used because they use one fifth of the electric power to provide the same amount of light as an incandescent bulb. Incandescent: 12 lumens per watt Halogen: 15 lumens per watt CFL: 50-60 lumens per watt LED: 100 lumens per watt High-pressure sodium: 200 lumens per watt
Need to know the equivalent of watts against lumens?
In this context, Watts are a measure of electrical power and lumens a measure of light output. So, depending on the efficiency of your light source the equivalency will vary dramatically. For example, a 60 watt conventional light bulb typically gives off 800 lumens. A frosted 60 watt bulb may only give off 500 lumens. A 13 watt CFL will give off that same 800 lumens, which is why 13 watt CFLs are often (erroneously) called 60 watt bulbs.
What is the lumen output for a 52 Watt halogen bulb?
Should be about 850 lumens. The same brightness is produced by a 15 watt CFL.
How bright is 7000 lumens?
This is very bright for indoor lighting, the equivalent of about 350 watts of incandescent lighting, or a 65-watt and 42-watt CFL pair (4200 and 2700 lumens respectively).
Why are LED light bulbs good?
LEDs use the smallest amount of electrical power to produce a given amount of light. Approximate data: Incandescent 12 lumens per watt Halogen: 15-17 lumens per watt CFL: 50 lumens per watt LED: 80 lumens per watt Sodium lights as used in street lighting produce 100-200 lumens per watt.
How many lumens in 85 watt CFL?
Power = Voltage x Current, so Current = Power / Voltage. {1 amp = (1 watt)/(1volt)}. At 120 Volts, then Current = (13 watts)/(120 volts) = 0.10833 amps.But at 12 volts, (13 watts)/(12 volts)= 1.0833 amps.
