Default GHL Mitra Owners club

I got my Mitra's hung last night and all I can say is WOW! These lights are unbelievable, the coverage is amazing, zero disco ball effect.
The only downside is the programming. It is standard GHL programming so if you have or have had a profilux you should be ok.
I have 3 over my 225 (72x32x24) and the tank is fully covered no dark spots or shadowy areas.

Yup, these lights kick arse! So you're keeping them then?

Have you calculated how long your pay back period is since switching to LEDs?

Glad to see someone else doesn't see any disco effect, not just me. I think Keener must has permanently screwed up eyes from watching too many color wheels spin.

I thought the programming is pretty good, are you talking about the software?

Yeah the software. It's not hard just a little clumsy is all. What does your program look like Sphelps?

Hmm I thought the light composser was pretty sweet but honestly haven't done much with it. It's kind of embarrassing how basic it is, basically just run it around 15K peek @ 80%. Ramps up in the morning from a dim red and then ramps down to a dim deep blue. I haven't had a chance to play with it since I bought it

I think that a lot more people won't see/notice the disco with these lights. Consider this though, you can see the disco with Radions but there are lots of people who don't ;-)

Also, I think Keener is a screwed up little Sissy Junior Member cry babie

Sub, I hear they're working on the Mitras Pro.

Mitras Pro! Well shoot I better wait some more then before pulling this trigger myself.

Can't the disco effect be adjusted by varying the height of the units above the waterline or playing with their position overhead? Or is it pretty much constant no matter what you do - "if you see it, you see it" kind of thing?

I played around a bit in my tank, with a different LED albeit, and If I turn off my pumps, then the disco disappears a little. I think pretty much every LED fixture will look great over air shining on the floor, but when you get ripples on the surface, it diffracts the different LED's at separate angles, which causes the disco. At least that's my theory. Possibly some of the disco effect varying between users has to do with the motion at the surface of the water. Less surface ripple could equal less disco.

I've had some experience with LEDs (way to much actually lol). When it comes to disco ball effect here is my ratings:
1 mitras (none)
2 radion (small amount)
3 ai sol (visable)
4 ai Vega (very noticeable)

The sol has less because of the lack of colored LEDs. All these were over the same tank on the same rack at some point over last year.

It is the surface water ripple that does it with my Radions. When I turn off the pumps, it disappears.

Solutions are easy. The real difficulty lies in discovering the problem.
