LED lighting?

If you read all the threads on RC, you will find that the efficiency claims being made are greatly exaggerated. The units DO use less power than my 250watt MH/54watt T5 fixture, however they also put out less light. The Solaris lovers all say that their corals are doing just fine with the less light which brings up the question of whether we've over-estimated the light needs of our photosynthetic friends. However the Solaris haters are very quick to point out that despite all the talk and claims, there are very few growth pic's of sps corals to back up all the talk.

Personally, the only advantage I see right now is the controllability and having all the features in one single package. BUT for the price they're asking, I could buy a Dimmable MH ballast, Dimmable T-5's and a controller like the profilux to run them all. I think I'll end up with one eventually, but I'm going to wait a few years and let the technology and competition mature.

Friends in the lighting industry also state many off these LED issues as well.
However, I love the built in timers and controllability of the Solaris. I also can see MH/Led units in future too, using 6500K -10000K for growth and dimmable LED from 0-20000K for colour.

PS: IMO dimmable MH ballasts, although cool, are expensive and reduce bulb life up to 40%.

LEDs don't yet create the same lumens/watt that the best fluorescents do, but they're improving, and getting better. Longer useful life, faster cycle time, infinitely controllable... little doubt in my mind that they will become the standard over fluorescent and HID in time. We just need more development on higher-output LEDs and bigger manufacturing/yeild to drive prices down.

Very negative review on the Solaris.

J&L's big price drop

Hmm ...makes me wonder...

You're going to get negative reviews no matter what you sell. This guys latest post is that PFO is going to make it right. We shall see what that means.

Price drop is directly related to price drops in the LED's....the bigger the demand for bigger and better helps PFO and their customers. There is also a new kid on the block with LED's for our hobby. Competition is also a good thing for the consumer.

The newest LED light out is the I4 and it hasn't been out long enough to see any results...about 1 month or so.

This guy doesn't state which light he has so I wonder if it is the first generation G4 because he seems to be comparing it to the 250 halides.

I have read every post I can find on these lights and it seems there are 3 or 4 at RC that are dead opposed to this type of light but from what I have read none of them has ever seen one of these lights let alone done any testing with them. I think if you toss out the reviews by those who haven't seen them and the reviews by those who are in love with their $4000 investment (not the light, just the investment) you will get a better feel for the light itself.

Scott you are so correct. When some people spend more than they can afford and get less than their high expectations, they blame the product. I own at 36" solaris G4 (I think, 8 months old) and I did not pay full price as full price would have been beyond what I could afford. I have seen a positive difference in my 33g over 20K 175MH with 65w 50/50 but then again I was not expecting a whole lot. Its ease of use and that there is no (hot spots of light) in the tank is nice because I can place frags evenly throughout the tank.

thanks alot this was very helpful,
i am still thinking of going with MH and PC lighting together
trying to find a good deal

Dont rule out HO T5's with those MH's.

I saw 2 models .The old and the newer. Quite a difference.The ones J&L were selling at clearance prices I think were the older models.They are improving these lights with every new model they bring out.
