One reason I changed from MH to LED was that the MH put off enough extra heat that my office (where my tank is) was uncomfortably warmer than the rest of the house.]]> Mon, 09 Feb 2015 17:06:54 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=74711&PID=583632&title=kessil-a360w-or-other-led-options#583632 <![CDATA[Kessil A360W or other LED Options : millsu2 wrote:I am hesitant...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=74711&PID=583621&title=kessil-a360w-or-other-led-options#583621 Author: Molli

I think with most anything you get what you pay for. If you buy a quality product from a known manufacturer with a good reputation you will be ok.

When you enter the arena of purchasing custom built stuff you better do your homework and understand what you are really buying. My current tank has only had water in it for about 3.5 months. Every piece of coral I have purchased has either been under t 5 lights or led lights. All coral added to my tank has colored up an unbelievable amount under my radionlights. I can hardly wait to start adding sps corals and see what colors these lights give. I'd never worry about my lights falling apart in to 3 years without radion doing something about it.

LED's do save a little money on the utility bill, but unless you are running more than 1 or 2 MH's than I probably wouldn't use the savings as a reason to go LED. I think the real advantage of LED's is the control it gives you. Being able to adjust the color and  brightness without having to buy new lamps or fixtures would be really nice.

John's offer is very tempting. He offers a very affordable fixture and it is something I could fix on my own if for some reason I couldn't take advantage of his lifetime warranty.

There are a lot more things that can be factored into the savings (home heating and cooling, Evaporation rates, etc..) It all depends on how many pennies you want to trip over trying to catch that dollar.

I had never really looked at the cost of running my system, so that is why my guess was way off. I am just not convinced yet to switch, but all of this information is great as it helps me get a better perspective on it. Also I do not have any chillers or other items that I could use in the figure. I would probably estimate 100.00 on the high end for my lighting setup, so that would cut the time by about a year. Still the savings are just not there from a cost stand point for me to make the switch.

Thanks again for the info, it is greatly appreciated.]]> Mon, 09 Feb 2015 11:42:57 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=74711&PID=583588&title=kessil-a360w-or-other-led-options#583588 <![CDATA[Kessil A360W or other LED Options : Don&#039;t forget to factor in...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=74711&PID=583580&title=kessil-a360w-or-other-led-options#583580 Author: Krazie4Acans

Don't forget to factor in the sale of the MH fixture as well.

I'm not sure about yours but It doesn't even cost me $40 per month to run my entire 40b with sump. So, I'm not sure how you can save that much on a 47g.

Thanks! I was hoping to see a savings close to 40.00 per month, and at only 5-6.00 per month it does not seem advantageous to go that direction. Also if I do calculate the bulb replacement into it, a 450.00 setup (Kessil 360 + goose neck) it would take about 3 1/2 years to pay for itself.]]> Mon, 09 Feb 2015 11:25:32 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=74711&PID=583579&title=kessil-a360w-or-other-led-options#583579 <![CDATA[Kessil A360W or other LED Options : Remember that LED&#039;s rarely...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=74711&PID=583577&title=kessil-a360w-or-other-led-options#583577 Author: Krazie4Acans

Remember that LED's rarely run at 100%. So your $2.80 per month for LEDs would be if they turned on instantly and stayed on 100% the entire time. No one runs LEDs that way. They ramp up slowly, rarely run 100% and ramp back down. Your savings will be higher than the $5 per month but I'm not sure you can calculate how much more.

You  also need to consider both operating cost and bulb replacement. Even with your figures your yearly saving on operation will be $60. Then you are saving an additional $65 per year on bulbs. So your yearly savings is $125 minimum for switching. At 10 years you would have had to buy a $1250.00 light in order to break even.

Can someone help me figure out the monthly savings on converting from my 250W MH to the Kessil 360? If I calculate it correctly it seems that I am not saving much, and that it costs very little to run the MH.

My notes:
A single 250W runs about 10 hours a day for 30 days, and that should be 2.5KW per day and 75kWh per month. My rate breaks into tier 2 every month with a per unit cost of 0.103467, so it costs 7.76 per month to run the lights on my tank.

Kessil has a max output of 90W. If it runs the same amount of time it would consume 27kWh per month. Using the same unit cost it is only 2.80 per month. This only saves me about 5.00 per month.

Did I figure this incorrectly? If so, then it does not seem logical to me to change from a MH fixture to an LED. Yes, there is cost savings due to no yearly bulb replacement, but that is about 65.00 per year. It would take me close to 10 years to pay for itself, and by that time I would need to replace it anyways.]]> Mon, 09 Feb 2015 10:44:35 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=74711&PID=583573&title=kessil-a360w-or-other-led-options#583573
