Orphek OR4 bars

I angled mine inward and have them only 8 inches above the water line to minimize the light spill over. What intensity/ schedule are you running them?

I plan on mounting 8" above water line as well. But I am getting the 70 reflectors...My kessils are 8" so I can't really mount them above. Anyone take par readings on these yet? I'm getting the blue plus

I have them start 5% at 6am, ramp up to 100% at noon and then back down by 6pm. I also have the lunar mod on at night. The heavy blue light makes them look dimmer than they really are so I am interested in the amount of PAR they put out. I think I will add an OR3 150 Violet/Day for full daytime color spread and figure out where I can borrow a PAR meter. The rental meters at BRS are currently out of stock.

What lenses do the OR3 have? Surprised they are going from 90 to 70 lenses since my only complaint with the OR3 is the blending and spread. If anything I’d like to see more like 120.

Think you can pick actually.

The OR3's have the older style lenses as seen here. The OR4's have reflectors. I do not think I will have a blending problem with the Violet/Days as there are only tow alternating color chips. The OR3 Reef Days have a random orange LED that do not blend well across the length of the bar. This was fixed in the OR4s.

The OR4's allow you to choose between 90 deg or 70 deg.

Funny, I was just thinking about that.
A retrofit reflector for the old models..and maybe for the new models.
Good choice and problem half solved.

I understand the 2 sizes but the loss of the wider angle is unfortunate.
Since generally the spread pattern is much better with reflectors it shouldn't be a terrible issue.

Lenses really were designed more for "high contrast" i.e shadows.
Does add punch though.
Reflectors are much softer i.e less harsh shadows.

The reflectors in the OR4's seem to give my tank more of a T5 look but when angling the fixture I can clearly control spill over and see a defined line. My old T5's lit up the entire room.

Just FYI to anyone who is interested. I was informed the 70 degree OR4's ship out Monday. My rep gave me the option of 90, but noted that the par is far greater on the 70, we shall see.

Overall par should be the same.
Just more concentrated .

How much did the OR4’s cost?

 

[ratzy82]

I bought the 5ft size and they were 350 ea

 

[padilla95624]

They are listed at $350 each. I got mine for about $250 each when I bought them paired with the OSIX controller.
