MarsHydro lights?

I really don't care what a company does with the money they make, they could throw hooker and blow parties for their employees, I can about service/warranty.

They could probably stand to spend a little bit of it on better components and properly upgraded configuration. Seems like they could probably afford it. I guess barbecues take precedence. Seriously, though, don't stock Mars. They're practically Happy Meal toys.
 
I'l check out ViparSpectra. I have a customer who owns a LED company but he retrofits commercial green houses and his systems are not cheap :( and couldn't talk to him into doing a budget line.
 
ViparSpectra has a warranty as well, I believe, but unlike MarsHydro, you're much less likely to have to use it. And even if you do use MarsHydro's warranty, their customer service reps will be standing by just to dick you around.

I was foolish enough to buy a set of 4x 600w mars hydro in an attempt to get my new grow room going, long story short, I used two to veg for aprox a month & half. It literally stopped working.
Another the LED's kept going.
I gave one to a friend & he said I should of paid him to cart it away.

(They were OK, when they worked. Not as good as hps I thought.)

So, the old hps lights are back out.
Now I'm out almost £500 quid on crap Chinese lights & looking about a decent set of cobs.

My advice, forget about the cheap shit. You get what you pay for in the long run.

It's actually true. There is no beating the first law.



From this quote, it's clear you're confusing heat with temperature.

It doesn't break the first law. And no I didn't. I was stating what temperature it left my room. I can touch the heat sink and all around the emitter with no issue.

You clearly are missing factors of your equation if you think that, watt for watt, HPS and COB run at the same temperatures. As I said, HIDs are incandescent, COBs are electroluminescent. Incandescents produce heat as a function of their design and are therefore much hotter. Electroluminescence produces neglibible heat secondarily.

It certainty does. If less energy comes out than you put in, it means energy was not conserved. The energy going in certainly doesn't cause the LEDs to accelerate, so where do you think that energy is going? (the void?)

You are seriously ridiculous. Read my last post. HPS creates heat using its energy because it has particles to excite. COBs put all their energy into electroluminescence which does not use heat to create light, therefore the First Law is not broken. You need to study more. I suggest you start with the difference between electroluminescence and incandescence before you make yourself look even more foolish.

Again, it's clear you're confusing temperature with heat. Heat is a measure of energy. Power is the rate of energy over a period of time. Temperature is the average kinetic energy of the molecules that make up a compound. An object being hotter or colder does not tell you the rate of energy transfer. For that, you'd also need to know the surface area of the object, the temperature of the cold body it's in contact with, and resistance of the interface between the 2 bodies. At higher temperatures, black body radiation also becomes a factor. Temperature is not power.

You keep saying that, but it doesn't matter. If the lamp consumes the same amount of energy per second, it outputs the same amount of energy per second. 100W go in, 100W come out. There is no void.

Again, go study incandescence vs. electroluminescence. See what you find. I'll bet upon reading the difference, you will find you are completely wrong. Like I said, HIDs put energy into creating heat to create light, as HPS and MH use excited gas and particles to create light. Electroluminescence does not use heat to create light. It is simply the product of an arc of electricity traveling over a phosphor chip face. It does not heat the chip to create light like HIDs do.

Therefore, First Law is still not broken. I'm done arguing with you, though. You're clearly clueless.

these sylvnaia bulbs actually have cree leds. i havent flowered with em yet but iv vegged large spaces with only 3 bulbs. 30w for like 3to 5sqft. these have saved me a ton of times when i run out of space for plants and just use a uhaul box with one per box. just got 5 more for 10 bux, might be the best value on light iv ever seen if they can indeed flower some nice flowers.

I use the Lowes Sylvanias to. 120-150 w equals using 15-17w w/ nice focused lenses. Use them in veg & I added them above my SunCloak last run. Pretty good lil light. 1-2 per plant @ 5k vegging 6" Potts works awesome.
They're doing a damn good job in my temp veg space. image.jpgimage.jpg
These Sylvanias Rock the house. $22 each @ Lowes. Great Veg & supplemental flower lights. Super focused 14• lens.

That's actually bad ass.
