A 250-watt HPS (High Pressure Sodium) bulb typically produces around 28,000 lumens at the initial phase of operation. However, this can decrease over time as the bulb ages.

What is the maximum number of lumens produced by a 150 watt light bulb?

How do you calculate the efficiency of a light bulb?

To calculate the efficiency of a light bulb, you would divide the light output (measured in lumens) by the power input (measured in watts). This will give you the number of lumens per watt, which is a measure of how efficiently the light bulb converts electricity into visible light. The higher the lumens per watt value, the more efficient the light bulb.


How bright is 400 lumens?

This is a bit less light than a 40W incandescent bulb (much less than a 9-watt CFL bulb, but twice as much as a 5-watt CFL mini-bulb).


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.


How many lumens are in a 150 watt incandescent light bulb?

A 150 watt halogen bulb will give off somewhere around 2000 lumens. These lights may give off up to about 2400 lumens.


How many lumens are in a 34 watt bulb?

The amount of light (Lumens) delivered by a light bulb cannot be determined by it's wattage. Bulbs of any wattage by different manufacturers can have different output (lumens). Everything else being the same, a 34 watt 110volt bulb will put out about half the light than a 34 watt 220 volt bulb, and a 12 volt one will put out about 10% of the light as the 120 volt one will.
