Only the 200W uses a Mogul base. The lower wattage bulbs use standard
incandescent bases. I didn't think they were any more efficient that a
standard fluorescent of the same wattage, am I wrong? FarmTek also makes a
big deal about the bulb's light spectrum, sound about like the marketing of
the different types of fluorescent grow bulbs.

Chuck,


Hey Ray... What area are you covering with the CFL (approximately)?
And do you have an idea about the bulb life and replacement costs?


The sources I've checked claim a "one year useful life" or, in another
case, 10,000 hours. The bulbs can cost anywhere from about $40 --$100,
depending on wattage. Evidently they are quite energy-efficent.

They use the mogul (oversized) socket.
