Approximately 15 lumens per watt for halogen, so 300 lumens.
What is more important to consider when buying a flashlight the candlepower or lumens?
They are one in the same just a different way of measuring the output of light. Much in the same way one would say a football field is 100 yards long it is also 300 ft. A rough answer to your question is 100 llumens equals about 26,500 candlepower. The term candlepower came about of course way back when everyone used candles in stead of modern lightbulbs. Llumens come from putting light on an object from a distance and maesuring the light at that point and distance. Very similar is horsepower and torque where horsepower is NOT a measured number on a dyno it is computed from torque output then converted from work over time.

Which is brighter 60 watts or 75 watts?
Watts aren't a unit of light. Previously, light bulbs could be rated based entirely on their energy consumption. A 60W light bulb consumes 60W, and produces light accordingly. A 75W light bulb consumes more power, and produces a little more light. Newer bulb technology like LEDs and CFLs consume less power, but produce a greater number of lumens (or candlepower). Thus, light bulbs are starting to display the lumens, one of the units for measuring light intensity. Note that the readings can be misleading, as the lumens shown may have a weird distance compared to other bulbs.
How many lumens are in a 60 watt incandescent grow light?

Trick question! Depends how far away you are from the light , or how far the light is away from the canopy/ coral, of course the closer you are to the light, the more lumens it will produce.
