Ok, let's hear it!

Like a 8' or a 10' tank.

This is a pretty fast moving thread.... But please don't get mad at me...LOL. I did not say or suggest that you or any non-LED users were misleading. Instead I said you were being misled,... big difference.

And in your case specifically, you are probably a good example of this. You have no direct experience with LED, yet you seem to be taking the side against LEDs and choose who you want to quote or back up your argument. If you want to talk about cost savings, why don't you go back and read my earlier post in this thread where I gave some real data on my usage and savings.

There's nothing to be mad over here. There's are all healthy arguments and thats why the forum is for.

I am not taking side again't LED, I am being against the cost savings

Aha, found the numbers. Sorry I didn't notice that post Can you please let me know how many T5s were you running (including the watt and the hours of running) and how many radions (which model? that will factor in the cost) you are running over the two tanks? I will do a calculation and see how things look. Your numbers are something that I needed. Thanks for posting those btw

Well, that's good (liking healthy arguments). Candor without malice, is what we used to say in the corporate world where I worked.

We used to live and die by all the numbers, and stretched and shrunk them every quarter (with the help of our creative accountants) to make our owners and shareholders happy. But I'm retired now, and have to say I hate numbers now, and do my best not to overly manage my personal finance, including how much I spend on reefing, etc. I just know it is a lot, and anything I can do to cut it back a bit (without compromising the quality and pleasure of my hobby experience) is good. So, no, I am not going to get out the meters and check my exact power usage, or calculate all my equipment cost and depreciation, etc. That would take much of the fun out of this hobby...

All I can tell you, is that my canopy (6 foot tank) was totally jammed with T5s before. They were very hot, and I know used a lot of power, incl the chiller and all the bulb costs. My LEDs on the other hand are very cool (in comparison to the T5s), and are basically maintenance free. Any adjustments are made with my computer.

Then I have concerns about that LED. why would my tank running on LED be any different to the next, I dont need a chiller and never have running LED.

LED's give out heat when driven hard, if the lamp does not have enough sufficient cooling which in turn effects the lamps PAR output then its not designed correctly.

My second generation DIY light uses a lot more Aluminium bars for the heat sink and so it dissipates the heat extremely well with NO fans whatsoever. Its all passive heat dissipation and just warm to the touch, even at full blast (280w) after 8 hours. My tanks were much warmer in the summer with halides.

I wonder if Brad and the others who experienced heat issues with LEDs have them inside an enclosed canopy with not enough air movement?

Yes, I had mine in a canopy.

I think ultimately some people made the original switch to LED for the wrong reasons. Focused too much on the hype of something or the hope of saving money and in the end didn't make sure they bought the right fixture for their needs which may not even exist yet. Doing so will leave a pretty sour taste in your mouth, so moving forward with another expensive LED adventurer can be too much to swallow for some so switching back to something more familiar makes sense.

For me, I moved to LED to reduce moisture in the house, which it did very well. And they also kept about 95% of the color for over the year I used them. Pretty impressed with that. They also have dimming capabilities, which is pretty cool. Another plus! But, I would rather have 100% of the color, which T5 is giving me. T5 is also an unfamiliar technology to me, I've never used them. But so far I'm impressed. My chiller comes on as much with them as it did with LED. The light looks nicer, the corals look nicer. I do not have dimming. I have to change bulbs. Both are negligible at my point in the hobby. I do not for a second believe any other brand or model of LED would have been different. They just don't provide what I'm looking for. I may even start liking my T5 better than MH. I know, right??
