Top LEDs are 200+ lumens/w. Try to find any HPS that produces anything near that.

This site does a decent job of showing how wattage =/= heat output. http://reptileuvinfo.com/html/watts-heat-lights-lamp-heat-output.htmlnot if they are the same wattage.
Totally unrelated sport or hobbie but the bowfishing world is loving the bringing about of led bulbs over hps for multiple reasons the heat being one of the top reasons being used. So yeah hps definitely has a higher heat signature than ledThis site does a decent job of showing how wattage =/= heat output. http://reptileuvinfo.com/html/watts-heat-lights-lamp-heat-output.html
Different types of bulbs showing different temps. The site does say that not every bulb was true to its wattage, but it's pretty pretty obvious from their measurements that different technologies produced different temperatures
Thats why 100w led can replace a 150w hps. Almost 50% more lumens/ watt. So in the course of one flower cycle, the LED saves me $2.88 per light for a total of $8.64. That's almost $10 /lb. Unbelievable savings.Top LEDs are 200+ lumens/w. Try to find any HPS that produces anything near that.
Exactly. LED and HPS dont produce the same heat at the same wattage. HPS is less efficient at producing light from energy and produces a lot more heat comparatively at the same wattage.Top LEDs are 200+ lumens/w. Try to find any HPS that produces anything near that.

This is exactly what heat load calculators state. 1 watt = 3.41 btu's.It’s not logic a watt produces 3.41 btus. You can’t change this. 600 watt hps or 600 led produces the same heat.
We're not talking about equivalent watts. Real watt to real watt, LEDs are far more efficient than HPS.Lol real watts not equivalent.
All the old purples had fans FWIWChanging the subject a little bit but I'll still discuss efficiency.

Looking at this graph of lm301b (the most popular diode in LED grow lights at the moment), wouldn't it be worth putting our LEDs in a fan cooled hood? A 100 cfm fan is 15w so to make this worth the watts, we would need to use 1 fan per 300w light if it reduces the light temp from 60c-30c. Does this make sense to anyone?
I'm talking about full on cooled hoods like HPS and HID.All the old purples had fans FWIW
You're able to use less watts because less heat and more light is created.Listen all im saying is when you say it "runs cooler than my hps or my cmh" of course it does if your using less watts at the wall. Maybe this link will help you all. https://pllight.com/how-led-and-hps-lighting-can-affect-air-and-leaf-temperature/
THAT WAS FUN.We're not talking about equivalent watts. Real watt to real watt, some LEDs are far more efficient than HPS.
Tents are the most common.Holy moly. The ratio of mid to large grows vs. tent grows sure has flipped on this site. Seems like everybody's in a tent.
with this arctic air I have never missed my HPS more. Was considering digging them out of the shop.Not if you need to run a heater
