MH vs LED POWER CONSUMPTION

[Anemonebuff]

I think people care because they want to have the proper knowledge about the products used. Misinformation is bad for the hobby and the critters we house. I'm not in the hobby to save a few bucks, but if a product is offered and it will, I will buy it and spend that saved money on other "cool" stuff like a new skimmer or "energy efficient" MP40.

These threads on LEDs are great because, not all LEDs are created equal, and there are new people joining the hobby who need to make informed decisions on their new tank.

I think all of you are missing the bigger point: Who cares?
People have their favorites and will defend them to the end of time.
The better question is: What do YOU prefer?
If you're in this hobby to "save" a few bucks, you're in the wrong hobby.
This is an ever-evolving industry and if it works for your system and your budget and you're happy with it, then it should be worth it to you, no matter which way you slice it.

Yes we all have our favorites....we are just comparing the facts and their uses to us. Hate to tell ya, but saving a few bucks is going to turn into much more substantial savings as time goes on as the cost of everything skyrockets over the years coming.

I'd love for this thread to stay open so we can see tangatank post the kilowatt watt readings on the LED driver.......

 

[fcmatt]

I also thought the same thing. I find this thread interesting but a bit confusing still.

It is almost like the point he was making fits better for the coral pricing debate
and less for hardware like LEDs.. go figure...

Why would people not want the most efficient light source?

Why?

Reefergeorge posted already with two meanwells running.

 

[James77]

I'd just like to see the explanation he gives for why his killawatt is reading 35-36 watts instead of the 154 watts he seems confident it should be, and how that relates to how we are billed by kilowatt hours.

I am very curious as well, my guess is he disapears

 

[nanojg]

you need to do a bit more homework bro. Amps are driving the system, not your watts. And he's saying its equivalent to 154watts dude.

Please explain the homework I need to do to come up with a meanwell 68-40 pulling 154 watts

 

[nanojg]

Oh dude you are not only ignorant in Engineering, but common sense as well as reading ability. Kindly please read my post completely, work with your smart calculator & then work on criticizing. Seriously now, you seem like a teen who knows everything.
1.4 Amps * 110 Volts = 154 Watts. This is the power drawn by the driver to step down & regulate 48 V DC @ 750mA to operate 12 LED's.

I do understand you can get an efficient driver, but the reality of LED practically is as stated above.

Seriously now, you have over 1400 posts, don't spoil your reputation with ignorant comments.

Looking forward to you kilowatt testing. Which of my comments gives you the impression I am ignorant?

There is a reason tangstank has not posted his readings in picture form. They do not support his argument. Our our LEDs as efficient or perfect as they could be, probably not. Is it a new tech that is in flux, yes. But it is very simple to go to the hardware store to buy lights and see that LED are producing the same lumens at a fraction of the cost of traditional lights. The 8 w = 40w labling is true and tested. By extention this will translate to LED on our tanks. You do not need to know engineering to apply common sense.

please debate the issue, not each other.

Why not run a so called " greener/cost reducing " tank to save a few bucks ? This hobby has many facets to it .
My tank consumes 4.3 KW a day . I would say that leaves me a lotta green backs for those high dollar designer corals .

 

[tangstank]

Here you go guys. This is the current consumed by

For

In case I did not mention earlier, I love the lighting everything set aside.

 

[James77]

Is that 133 watts or 1.33 amps?

 

[James77]

Looks like amps you are reading to me.....what does the watts read? We are billed by kilowatt hours, so watts are what we measure.

 

[tangstank]

Oh by the way for all the skeptics, here is a pic of my apex. It is a little higher than Kill-o-watt & that is the PF.
Look into Amp_3. This is with all outlets turned off & only the LED on

& this is what it looks like

FTS

The LEDs are connected to just 1 reflector, I will be doing the other 2 with my Buddies help this week.

 

[jmchzn123]

This is the wrong thread guys. There are SUPER EXTENSIVE threads that answer ALL these questions and more with data and graphs and purdy pictures. Some of the contributors are engineers. Like me you guys are not so versed in the science of it. I have been using LED's for about 10 yrs...They only get better. My last fixture the bulbs (emmitters) lasted 7 yrs. Just got AI Sol Blues...I will NEVER go back. Ever. Most of RC will have gone through 3-4 light set ups before I need bulbs!......Just Sayin.

 

[James77]

Why won't you post the watts your killawatt is reading, tangstank?

 

[tangstank]

Here you go.

James, you got to learn some patience buddy LOL
