I think if moneys not an problem (as op stated) there is no need to use anything but the most efficient lighting these days
happy new year - to all growers worldwide
to get the best for the money in 2018 - light/energy efficiency will stay an important factor.
Smarter light builds will have higher efficacy @ decreasing costs.
A high power lamp build will always produce an important amount of heat -
as i am a watercooler of led light, i know this will be a ~65-80% of the inverted electrical power.
We know that cool led light can increase light efficiency ~15%
- we drive our led chips @ low current and
use relativ expensive heat sinks and additional fan power to get a good heat management.
But aircooled led light imo lacks the ability to store the heat and use it in a smart way.
So aircooled led light can reach 20-35% light and energy efficiency...
...but light + heat cogeneration with a watercooled set up + heatexchanger can triple efficiency and reach ~85% energy efficacy.
Regardless of the type of led and driver you are going to use in a watercooled led lamp -
you can harvest up to 60% of your input power as hot service water in your household.
With 1200W-1600W watercooled led lamps -
@travis11952 - you are able to produce an amount of ~ 300-400L hot water every day .
If your grow room is close to bathroom or kitchen,...
or may be you want to use your watercooled led lamp
to heat your grow room during winter night...
may be you can substitute oil or gas water heating - and have green savings...of CO² + $
that makes your and everybodies electricity bill smaller - in concept of a more cost neutral set up.
In combination with pv- and/or wind power, e-mobility - it`s all you need for an autonomeous future: --- Electricity, light, hot water, heating during winter, weed + tomatoes, mobility....
if money is inverted in green tec - we all profit in the global race against climate change.
There are quite a few watercoolers here on RIU with different set ups ---> put "watercooled" in the search function above ^ and you can enjoy hours of interesting posts.
Watercooled led tec means DIY or prefabricated lamp builds that eg. can start @ 1600 US$ / real 1600W for 2 lamps(800W each), + meanwell drivers, + cree, citizen, samsung or any other standard chips + 300L heatexchanger / water boiler + paypal incl. -
