As a cave manager, I would be more concerned with which type of bulb would reduce (eliminate??) the algal growth on the formations that are near the heat of the lamp.

Sure, every lamp, even an LED, ultimately creates one watt of heat per watt of input, but the question is how much of the energy is useful light on the way to becoming heat. LEDs aren't as much more efficient than other lights as most people think. They seem brighter because their output is inherently focused. They aren't really more efficient than compact fluorescents for area lighting. Halogen bulbs might be an inexpensive substitute for ordinary light bulbs once the clowns in Washington have outlawed the 25-cent kind. -- Mixon --Mixon ---------------------------------------- Forgive your enemies . . . after they are hanged. ---------------------------------------- You may "reply" to the address this message came from, but for long-term use, save: Personal: [email protected] AMCS: [email protected] or [email protected] --------------------------------------------------------------------- Visit our website: http://texascavers.com To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
