Led guys chime in

This dude is hopeless. He's trying to explain how electricity works to actual electricians, and failing.

That's an intelligent theory although that's not the way it actually works. If you have a 600 W light you are not going to get more than 600 W out of that light because you're more efficient you're going to utilize more of the original 600 W than another light at 110 V but you're still using the same W either way.

You're 250 V lamp might actually use 596 W of the 600 W Whereas the 110 V lamp which is less efficient might only get to utilize 570 of the original 600 W. But at the end you're both using 600 W and your bills will be identical.

You guys are truly clueless because you're talking about a light and the lights efficiency starts when the power hits the light that's where the efficiency is in the lamp that's what we're talking about so in no way are you changing the amount of W coming in or being used all you're doing is using the W coming in more efficiently. I highly doubt that either of you are electricians.

Notice how they only give you one rating for W up top? That's because regardless of whether you use 120 or 240 you're still using the same W..

That's only true if you are running at 100%, and if you are running at 100% it's also true that you will have 4% more light output from 240v vs 120v, which means that you can dim your lights down slightly to get the same amount of light (or purchase less fixtures for your grow room), and enjoy the savings. Or you can crank to 100% and enjoy increased light from 240v.

I'm glad you are finally agreeing with what I said previously which was there is no savings unless you turn off your light to compensate for the extra efficiency.

Turn off your light? Dude you're off the rails now. How's your current grow coming along anyway? Oh wait you had to chop 3-weeks into flower because you majorly fucked up.

You said it yourself that you could dim your light 4% to save money and make up for the efficiency but now you look like even more of a mockery because obviously you don't understand that when you dim your light it's going through a power cycle at a 100 -120 fps so that your eyes can't see the power cycle but that's exactly what your lights doing when you dim it it's turning itself off and back on. So when you dim your light you're doing exactly what I said you could turn your light off to Make up for the efficiency. The fact that you are laughing at that proves furthermore that you don't know what you're talking about.. But of course you knew that because you're an electrician right?

fps? This isn't video. I'm laughing at you because you are stupid. Everyone else gets it except you, but somehow everyone else is wrong, and you are right. However you still haven't told us what your education is exactly? Maybe a few YouTube videos is where you got your credentials?

Stop making a fool of yourself vision is also measured in frames per second. Your vision is about 60 fps Max.

"Leds work using dc voltage. The higher the voltage, the more light the give out. The higher the voltage, the more current they use, which relates to energy. Manufactures use various ways of changing the dc voltage to change the brightness. Some just change the voltage using a transister but this is the most expensive and least efficent way. Others cut off the current for part of the time, thousands of times a second, making the Led blink so rapidly the eye does not see it blink, it just looks dimmer.

In most LED light systems dimming is essentially a very fast cycle (100 to 120 times a second) turning of the LED on and off. It doesn’t consume power in the off periods while it operates near its best efficiency during the on periods."

Stop making a fool of yourself. You just can't admit wrong. Must be something deep down.

You are confusing frame rate with refresh rate (Hz). Standard US AC power is 60Hz. When you use an LED driver you are converting the alternating current to direct current. Direct current does not have a refresh rate.

It's pretty cute that you quoted something that you googled from quota.com though.

If there's people out here buying marshydro or spiderfarmer and was the same price they would cave atleast I get a 5by5 flowering footprint honestly spectrum blackdogs are much better lland the plants nodes are more tight photontek has better design iv compared same cuttings and both have pros and cons but I don't seem many people making comparisons just opinions
