Greetings!

I am an owner of a newly setup 55G that im going full-planted.

I retrofitted an old thin strip light with AH Supply's 2x55 kit, thinking I was getting 2WPG.

However, after assembling, the 2WPG looks 3 times brighter than my 2WPG Coralife 30" Striplight on my 29g tank.

I asked Jim (awesome guy) at AHSupply and he said that his 2x55 lights put out 10% more light than a similar 4x55 Coralife fixture. He isn't kidding.


So, does this mean I effectively have 4WPG? Or is this what 2WPG should really look like? I should post a pic when I get home to highlight the difference.

Thanks!
 
Unless you are getting numbers from a PAR meter, I would still say "2wpg" is what you should be using when choosing plants. I would guess he bases that 10% number on the better reflectors, but I'm not positive.

You are correct; he said this his reflectors are much more efficient.

The tank is incredibly bright.. maybe i'll get another 2x55 and get Co2.. but then I wouldn't be able to tell if it was night or day in my living room.

awesome!!! did you do each strip or just one long one ( I have 2 seperate lights from a fifty five and I would love to redo the lighting!!!
 
He represents his product honestly. AH Supply reflectors are definitely superior to Coralife. I have a few 55 Watt Brighty kits on different tanks. Where it is most evident to me is in my 80gal. I have a 4X65W Coralife in the back and a 2X55 Watt AH Kit in the front. I don't need a Par meter to see that the light from the AH kit penetrates and distributes far better than the Coralife. In retrospect, a 4X55 AH Kit would have been plenty to keep this tank High Tech.

Their reflectors are also available for purchase separately for those that want to modify or DIY.

He definitely does represent his products honestly; the difference in lighting is incredible between Coralife and his Bright Kits.



So, it seems that even though the light looks to be 4WPG, it really still only is 2WPG?

Adding Co2 and expecting to grow medium-light plants isn't a reality?

Technically, to figure your WPG you need to figure your actual water volume.
ie; inside tank measurements, subtract substrate depth and water level.
Then add 10%. This is a true range - IME.

It is very much a reality, even some high light stuff.
 
are the coralife bulbs the same spectrum range as the AH supply?


could be you are seeing a diff from the spectrum range(many consider the K rating as the same) some color may appear brighter
 
Seeing is not always beleiving. Green spectrum may seem more bright in human eyes compare to others. So Even they have same K the spectrum can still differ. How about trying a par reading. I heard both of them are good so it's only fair to compare them by PAR readings.
