Solaris has gotten there first to be sure and from the reviews I have seen it is a great unit. As far as the price point being to high, that all depends on what you are looking at. Always consider that the LED until will outlast most of our interest or time that we stick to the hobby, they...

These are XLamp LEDs from the company I work for, Cree. They are high power, high efficiency, cool white LED's. I am currently using 20 of them driven at only 350ma, the low end of their spec. I plan on testing them at higher driver currents, but for now I am starting at the low end. I just...

Here is your update. I added 10 Royal Blue LED's to the mix to bring up the color temperature. The measured color temp is approx 17,500K. This is an average since at certain measurement points the spectrometer could not calculate the CCT. As you can see the blue is peaked now. The color in the...

Here is what the first fixture looks like.

Thanks for the correction, wikipedia to the rescue, I understand now. So it is a measure of the area of the spectrum rather that the complete spectrum. I can get that measurement from our spectrometers. I found out that a company called solaris has beaten me to it. They offer a light like...

Another thought, what would be cooler than a light that would allow you to dial in extra Blue or red, or yellow, or orange. Its your choice depending on the tanks needs. Want the blue hue of an Actinics then turn up the blue, ant the color to stimulate the plant growth then turn up the reds...

Let remember that PAR is not a measurement of light, PAR as I know it is an acronym for Parabolic Aluminum Reflector. They are used for metal halides since they are a round bulb and if you cross section it only 180 degrees of the bulb is directed to the tank, the reflector is used to bounce the...

Nope, we are primarily a die maker. The XLamp line is the only one that we package. Most all of our other line is sold as dice/wafers. Most all cell phones use our die for edge lighting and most of the high end flashlights are using our product as well. There are also interior lighting...

Good info, we can do that. Our production can be targeted toward certain color points, we bin from cool to warm light. Ranging from 4500K to 8000K. The device has a 100 degree viewing angle. Here is a link to the datasheet if anyone is interested...

I use a Sigma APO Macro DG HSM 150mm true macro lens and it is great. I was 525 when I purchased it late last year. I had great reviews in the mags, does a true 1:1 macro, and a non-rotating front element while focusing and also has the ability to focus to infinity which allows it to be used...

Hello all, I am new to this board. I took a long hiatus from saltwater tanks (8 years). All I can say is WOW have things changed. I am setting up a small 30 gallon reef and right now it only has the water, substrate and about 30 lbs of live rock. I plan on adding and addition 30-40 lbs more...

Very nice tank. I have got a ton of questions for you. I am also starting a 29g tank and would appreciate any startup, setup and well any information you can provide. The last time I ran a salt tank was over 9 years ago and man have things changed. Is it a lot of maintenance keeping that...
