Are halogen lights OK?
 

Hi again, everyone!

Does anyone grow under halogen lights? What are the pros and cons? I grow
indoors and I'm looking into supplemental lighting. So far, halogen
fixtures look like my best option.

Thanks!

They give off a lot of heat for a fairly small amount of usable light.
Fluorescent lighting has good light and not to much heat but have to be
quite close (1 foot or less). Compact fluorescents can have decent
intensity but still have to be relatively close(1-2 feet). Metal halide or
High Pressure Sodium give you the most bang for the buck. Watt for watt a
HPS bulb will give off at least 4 times as much useable light as a halogen
light and 1/4 the heat. Unfortunately MH and HPS don't have the most
attractive fixtures.

Halogen lights use a lot more electricity and put off a lot more heat than
fluorescent, Metal Halide, or High Pressure Sodium lighting. If you need
something that will look nice in your living room then halogen might work,
but it is not the best option for plant lighting.

Murri,

I would think that you MUST have another source of light, as at a
distance
of six feet, a fluorescent bulb is of almost no value whatsoever.
Remember,
it's an inverse-square thing - twice the distance, one-fourth the
intensity,
three times the distance, one-ninth, et cetera.


The inverse square law applies to point sources. From diffuse sources
such as fluorescents, the fall-off in intensity is more accurately
expressed as the inverse of the distance.

(Think of a fluorescent as being a large number of overlapping point
sources)

Nonetheless, the fall-off is substantial. Six feet is a long way.

Thanks, everyone! I'll keep shoppping.
