i beg to differ that its above to LEDs, the technology is still limited in life and size.also the lower loses when converting electrical engery into RF.
as for effeciancy its still in the 90 lumens per watt, making it in the same range as MH
T5HOs T8 and some LEDs. still not close to the same light output as a normal output T5 which put out in the area of 13 lumens per watt.
the heat is anotehr factor, the sulfur burns through the lamps, so imagine what they will do to the water temperature, not even MH
burn through and you could bake with MH
the cost for plasma lamps still wayyyyy to high and even LEDs look cheap compared to them.
carey, i wouldn't worry to much abotu the tang, its probably just havign fun alone and eatign algae
plasmas have a ways to come before they become a real contender, just look at plasma TVs. they were discontinued for years until they slightly improved them, but they are still behind LCD and LEDs
