    Interesting. Still don't understand why the primary 120 degree optic is not as good.

    Seems very functional but also looks like a way for a lens punter to stick with lenses without having to say the unlensed opposition was right (for wide shallow tanks) all the time.

    Disclaimer: I'm on the fence as well with the lens vs unlensed debate.

    I read it, but if any secondary optic results in 10% loss in par (assumption based on reading) then it's difficult to believe that it's better than primary 120 degree optics without the loss.

    I am going back to T5. My sps has been under T5 for the last 2 months and they look much happier. That said I cant wait to give feedback on the new 1.5m Razor unit.

    secondary lenses allow the manufacturer to change and customise the LED to how they want it to work, whether its a waste or not, time will tell.
