......is sorta beating around the bush, obfuscating and pure nonsense ......talking about efficiency when the the subject is heat vis-a-vis tent temperature, but I see the marketing angle. Every W is heat generated, nothing is "lost" to "heat", no "reasonable" amount of heat is produced......A Telos generates 245 W of heat, in one form or another, just like a 600 W HPS bulb produces 600 W of heat(There's a ballast too, but lets not nitpick), in one form or another.......please refer toin case any doubts lingers....lol
I think I understand what you are saying, you mean the the law of conservation of energy. Heat is a measure of the transfer of energy between thermal systems by conduction, convection and radiation. Work is the transfer of energy by something other than heat, in this case useful light between 400-700nm which is transferred to your plant as electro-chemical energy. If the Telos transferred 0% of the energy in as work and 100% as heat then it wouldn't be very useful! Have a look at the first law of thermodynamics if you want to learn more.
When talking about the Telos I thought it was important to mention that around 50% of the heat transferred per watt will be from the heatsink to the ambient and atleast 10%+ as IR in the beamangle. I said this because HPS an CMH lamps produce a much larger amount IR and little heat by convection or conduction by comparison.
In both the hotter and colder months leaf temps can be hard to mange under HPS because of the amount of IR in the beamangle directly heating the leaves whereas the heat from an LED system is mainly transferred through the heatsink into the ambient. It's much easier to increase or decrease the ambient temperature of your room to control leaf temperature than it is to shade your plants from a high intensity of IR. That said, I'm not knocking the 315w CMH lights for home growers, they will be much easier to manage than a 600w HPS and they seem to do a pretty similar job growth wise.
Hope that clears things up for you!
