I agree with Bean ... this is getting old. And I'm speaking as an owner of a H4. Can we all stop rehashing the same arguments? Yes, the laws of thermodynamics means a watt is a watt. Yes, MH reflector technology and bulb choice plays a huge role in the available PAR and I agree it would have been interesting to see how the Solaris stacked up against a Lumenarc and a better bulb (though I agree with the MH proponents that PAR numbers are likely to favor the MH).
But I think there's something undeniably cool about the Solaris. The amount of heat radiated from the bulbs is much less than any MH I've dealt with including 150s, 175s, and 250s. My chiller is coming on much less than it was previously with 2 x 250s. The change that happens in Solar mode from sunrise, daylight, cloud cover, sunset, and night mode is really cool to watch and the organisms in my tank seem to respond favorably to the changes.
I'm an early adopter and often end up on the bleeding edge of tech. As such, I've been burned before. But I would say that I'm happy overall with the change I've made from 2x250 MHs. Could I have accomplished similar goals with going with lower wattage MHs? Possible ... but the decrease in heat radiation into the tank and the intensity changes of the light would have been difficult to replicate with MH (maybe with an Elos Suncolor ... ) Do I think that the technology is ready for mainstream adoption? Probably not - there are certainly some very promising new technologies on the horizon that will drastically change the cost-effectiveness of the LED lights and therefore, most people may elect to wait until things settle out. Ultimately, the thing that will determine how good this light is how well the organisms in the tank do and obviously, it'll take a while for us to really document that.
Can we all agree that the points have been made and we all should move along? I look forward to seeing more posts from owners sharing tips and how things are doing.
As a tip from me, I've determined that despite the documentation and what Pat told me, the time offset control on Solar mode works backwards. I.e. - if the lights are coming on at 6 AM and you want them to offset by 2 hours (so they come on at 8 AM instead), you put in -120 into the time offset, not +120.

PS: stimpy - I've got 80-90 times flow turnover in my tank as well.
