finally someone who isn't brain dead and understands led vs hps growers, that'll just bash each other heads.
Going from HPS to LED. Worth it?

Check my thread, starting on page 129. Any questions you have about COB LED lighting and it's ability to grow quantity and quality will be answered in technicolor.

So if you use 2/3 of the power to make the same yield, that's your savings. PLUS bulb changes, so that's 3-6 of those, PLUS HVAC cost savings in purchasing and operation, so yes. You're coming out ahead. Compared to HPS, you've paid for the lights- and I haven't even factored in increased yields or better quality!
"The rest of that is heat transfer to some bio chemical process in the plant" ...which would be THE WHOLE POINT, wouldn't it?
LED is better than light bulbs. Yes, it's more expensive up front, but that's the last time they'll cost you more than a light bulb bar system.

..I'm not an LED Evangelist, what are you talking about? And I didn't jack anything, I was getting harassed and I responded in kind. Your perception is clearly shit. Enough of you, though.

Well-fucking-put. To hell with that guy. Doesn't even know what he's talking about.

Increased quality? That's new to me and ive been using leds for 4 years.

ttystikk, yes I know what you mean. I'm not bashing at LED/HPS users. Trying to point out like it's how HPS users debate over Vertical or horizontol grows, I remember seeing your post years ago on hps verticals. didn't you have people bashing on you before for going vertical? however my opinion i thought it was a great idea, that vertical was more better as you're using the whole light.
now to the op's question, what does he mean by is it worth it? yes it worth in efficiency and in the long run, but how long is your run going to be and last for.. do you understand?

All I'm saying is COBs are at least on PAR (lul, get it?) with HIDs. LED panels are shit compared to both. My only reason for saying COBs are better is simply due to the lesser energy consumption, greater efficiency, less of a fire hazard, and simple stuff like that. You need 1/2-2/3 the energy required for HID in a COB setup, space depending. Incandescents use heat to create light, therefore the light is not optimized because much of the energy is wasted to heat the filament. With COB, it uses electroluminescence, which doesn't require heating a filament, the arc just goes over the phosphor chip face to create light.

COB's create heat, they heat up when energy is passed through them, that's what the heat sink and fans are for, to remove that heat or they would over heat and burn out.

I didn't say they don't create heat at all. I said they don't use heat to create light by design. HID does.

wrong , it's gas that has an electrical current running through it to make it excited. HPS = HIGH PRESSURE SODIUM GAS
Olive Drab Green

Yes. HEATED GAS. Hence the pressure and electric.

Diagram of a high-pressure sodium lamp.
An amalgam of metallic sodium and mercury lies at the coolest part of the lamp and provides the sodium and mercury vapor that is needed to draw an arc. The temperature of the amalgam is determined to a great extent by lamp power. The higher the lamp power, the higher will be the amalgam temperature. The higher the temperature of the amalgam, the higher will be the mercury and sodium vapor pressures in the lamp and the higher will be the terminal voltage. As the temperature rises, the constant current and increasing voltage consumes increasing energy until the operating level of power is reached. For a given voltage, there are generally three modes of operation:
- The lamp is extinguished and no current flows.
- The lamp is operating with liquid amalgam in the tube.
- The lamp is operating with all amalgam evaporated.
In practical use, the lamp is powered by an AC voltage source in series with an inductive "ballast" in order to supply a nearly constant current to the lamp, rather than a constant voltage, thus assuring stable operation. The ballast is usually inductive rather than simply being resistive to minimize energy waste from resistance losses. Because the lamp effectively extinguishes at each zero-current point in the AC cycle, the inductive ballast assists in the reignition by providing a voltage spike at the zero-current point.
The light from the lamp consists of atomic emission lines of mercury and sodium, but is dominated by the sodium D-line emission. This line is extremely pressure (resonance) broadened and is also self-reversed because of absorption in the cooler outer layers of the arc, giving the lamp its improved color rendering characteristics. In addition, the red wing of the D-line emission is further pressure broadened by the Van der Waals forces from the mercury atoms in the arc.
Not technically heat, it's an electrical current(arc) run through the pressurized gas.

Fuck off. Contribute something, grow a single plant, then you can talk to me. Then I'll still tell you to go fuck yourself.
Everything you just posted loterally states that it uses heat to produce light.

The higher the temperature of the amalgam, the higher will be the mercury and sodium vapor pressures in the lamp and the higher will be the terminal voltage. As the temperature rises, the constant current and increasing voltage consumes increasing energy until the operating level of power is reached. For a given voltage, there are generally three modes of operation:
The first and last states are stable, because the lamp resistance is weakly related to the voltage, but the second state is unstable. Any anomalous increase in current will cause an increase in power, causing an increase in amalgam temperature, which will cause a decrease in resistance, which will cause a further increase in current. This will create a runaway effect, and the lamp will jump to the high-current state (#3). Because actual lamps are not designed to handle this much power, this would result in catastrophic failure. Similarly, an anomalous drop in current will drive the lamp to extinction. It is the second state that is the desired operating state of the lamp, because a slow loss of the amalgam over time from a reservoir will have less effect on the characteristics of the lamp than a fully evaporated amalgam. The result is an average lamp life in excess of 20,000 hours.

Yup, the more electricity it uses the more heat it causes and light, just like any light source....light is radiant energy....

I just proved you wrong. I just highlighted where it states it uses heat to create light. COBs produce heat secondarily. HIDs produce heat as part of its standard operation.
