GET OFF MY LAWN
No one has disputed what the site says, however common sense and a look at the led manufacturers spec sheet will tell you the fact vs. What a company wants to sell you. Most companies that produce motor oil say you HAVE to change your oil every 3K miles. Or they sell you a "high mileage" motor oil at an increased price. Well the facts have been around forever that a standard change should be around 5K or even longer depending on manufacturer / engine even with standard oil.
For example. Fish stores & retailers claim mh bulbs need to be changed every 6 months *LOL* I usually changed mine every 1.5+ years and that was usually because I wanted to try a different unit. I would then give bulbs away and some would claim they used them for a long while after that as well. Or the bulb would crap out in the first few months, went through my share of that.
The maxspect unit is a non optic system so you do not need to hang it up way high to avoid hot spots & so forth. In general, many of us run our units very close to the waters surface, myself running both g2 160w units at 3" above the waters surface. Or just keep it as high as you want as long as the par is what you are looking for. Just a thought
