|Veritas||might as well go for the Ray2 if your aim is high PAR. A Planted+ added on to the Ray2 looks really nice though.|

|Spike32||I have a 40G breeder tank I'm currently in the process of setting up (slowly). I already have a 36 inch ray II, and I know I need one more light fixture on it to not have the back and front be very dim. What I don't know is if I should get a second ray II, or a fugeray or planted +. I'll be dosing ferts and pumping in CO2, so my goal for PAR is minimum 60, max of about 90. The dimensions of the tank are 36X18X17. Thanks|

|Shark_||Also, rather than showing PAR via an end view like all the charts on page 1, does anyone have PAR shown from a front view?|

Edit - I realize nothing you said claims that the LED's on the far right of a 4ft fixture are affecting the PAR on the far left side of the fixture, just that the spread of the LED's is greater than 2ft, thus creating more par on a 4ft fixture than the 2ft fixture.
I guess what i'm really looking to find is the angle of spread on each LED. Aren't most LED's 120°?

If you put one old fashioned incandescent floodlight, say 25 watts, in a dark room and point it at the ceiling it will light up the room dimly. Add a second and the room will be brighter - even if it is pointed at a different part of the ceiling (because they are wide angle floods). Add 30 of these lights and you now have overlapping coverage all over the ceiling - and 800 watts total.
Say the room is very long and you started at the right end. Even as you add more light to the left side of the line of lights the overspill is going to increase the light hitting the right side too, and (jumping back to an aquarium) give more PAR to the right end as well as the left.
In lights that have narrow optics this effect would be much less (more like a line of narrow focused spotlights)

|Shark_||Can someone tell me what optics are used on each of the Ray II fixtures? Or where I can find the information myself? Thanks|

|Deano85||What's the point of par values in free air?|

planted + is a fuge ray
In my opinion one Ray 2 is brighter than 2 planted+
I agree with your LFS- you might try it in combo with a T5HO

|TheTruthAndretti||im sorry if these are dumb question just the guys at the lfs told me that 2 fugerays would be better than one ray2|
|11-19-2013 09:51 PM|
|TheTruthAndretti||so one plant + or ray2 is stronger than 2 fugerays ?|
|11-19-2013 09:39 PM|
instead of 2 Fugerays I would really suggest one Planted + or one Ray2 (their strongest light) 12" wide is just too narrow for 2 lights (just my opinion)
are you planning on injecting Co2? Going high powered light and high demand plants without it is kinda asking for trouble.
One exception on the 2 light thing - if you are going full bore with a Ray2 and Co2 injection you can add a Monster Ray light, it just adds major boosted colors.

|TheTruthAndretti||so with 2 of the 24 on my tank i will be able to grow high right ?|
|11-19-2013 09:26 PM|
I think that's a 20 gallon high? One 24" fugeray would probably be enough for medium light plants ( can't open the par charts on my phone) and yes, you definitely want the dual 7k lights.
They also just released the Fugeray Planted + light, you might want to consider that (a little more growing power and color)
