mfinn, hopefully they do cover Did you order the new lens? Not bad for $35 the shipping seams a little steep for the size of them.
No I didn't order the new lens.
I have 3 gen 1's over my 6' long 240 and a single gen 1 over my 50, which is
30" x 20".
When I said that 2 wouldn't do for a 6' tank, maybe I spoke too fast.
I'm currently getting good coverage with my gen 1 over the 30" width on my 50.
So, if they have a wider spread lens, then maybe it would add a total of another 6"..........................................
probably wouldn't get the best par on the edges, but who knows.
I have been bugging EcoTech to do some testing on their lights to show exactly what kind of par you get on wider, longer tanks, posting the results.
They just keep saying something about,,, "it's in development." Or something to that effect.
