Re: Altman Comet follow spots
I have no personal experience between these two products and it seems the spec sheets are inconsistent, but generally wattage is only part of the story. Other factors include:
- Type, lifespan, and efficiency of the lamp - long life bulbs are lower brightness for a given wattage, and HMI has many more lumens per watt than quartz halogen, and there are lots of grades and subtypes of quartz lamps
- Efficiency of the fixture - its ability to capture and direct the light from the lamp vs losing it inside the fixture our out the back
It is not hard for me to believe that a 1000w old-design lamp in a poor fixture is outperformed by a high-tech 360w bulb in an efficient fixture.
