Hehehe, As you can imagine he has been flooded with Volunteers.
May need some in the future for other products but he's covered on the LED's.
More about lighting:
T5 +: higher par than both vho and mh per watt = greater intensity
last longer and use less electricity = cheaper to run and replace
less heat produced = less water evaporated which extends the life to your RO/DI unit and less $$ to cool your home
T5 -: currently the actinic bulbs made aren't on par with vhos (although uri i think is coming out with a new line soon)
better for tanks 24" deep or less
MH+: "shimmer lines"...nuff said
great for tanks greater than 24"
MH-: must replace every 6-12 months (depending on bulb and usage)=more $$
require actinic supplementation for daylight/dusk effect (you can use 20k bulbs but only get "on" or "off")
require more wattage=more electricity=more $$
produce more heat = higher water temps = fans/chillers almost required (more so in southern states) = more $$ in one form or another (added electricity, cost of chiller, more evaporation etc.)
