New Red Sea Max Reefer™ LED fixtures COMING SOON from Steves LEDs!!!
New Red Sea Max Reefer™ LED fixtures COMING SOON from Steves LEDs!!!
Well I did it... I placed my order for my 1st RSM 250 major upgrade (as many of you know.. I have always run near 100% stock) but after much research & study, I decided to go with Steve's LEDs

Very excited - wish me luck - more to come...

Awesome article. I will like to add that measuring LEDs is definitely more difficult than MH. Since MH light is broad spectrum with minor concentration on certain wavelengths, a standard PAR meter works great. Since a properly designed marine LED system uses LEDs with wavelengths that are aimed at coral zooxanthellae's photosynthetic peaks in massive amounts - this quickly saturates a standard PAR meter's sensor.
The proper tool for measurement would be the radiospectrometer. Yes a 10X intensity increase when compared to MH is a bit high, but not as outrageous as you may think. MH outputs light across a huge spectrum from ~380nm - 800nm+. Lower wavelengths take a significantly larger amount of electricity than the higher wavelengths. Note: that is not all usable light to corals. Corals typically absorb the light in the wavelengths where their photosynthetic peaks lay, everything else is reflected.
I can't speak of the Cree LEDs - we only sold those for a while, and had a huge issue with reliability from them. The Luxeon ES (and latest version of the Rebels), when measured in comparison to a very high end MH bulb, while using a radiospectrometer in the chemistry lab at the University of New Orleans, showed that the Luxeon ES fixtures that Steve's LEDs makes, using our custom LED combinations - has shown that they actually output about 8.2 times the amount of "usable" light than the MH. To define "usable light" I mean producing light in massive amounts at specific wavelengths that corals can actually use to photosynthesize and grow. Granted, the MH and LED overall lumens comparison results in LEDs being only ~2.1X more efficient at creating light (heavily depending on the manufacturer and color temp of the MH bulb. But in an aquarium, the whole purpose of selecting a suitable light is to find something that 1) makes corals grow well, and 2) makes corals look awesome.
That said, a good LED system will be able to do everything a traditional lighting fixture can, all while having an even brighter appearance than MH, T5, or any other lighting system, all while providing a significantly higher amount of usable light.
Here's the kicker: MH bulb manufacturer's specs - although seem amazing on the box, start to degrade almost immediately, within a matter of hours. So MH posted specs are only valid moments after plugging them in, and degrade dramatically, where the bulb is barely even usable after 1 year necessitating yearly bulb changes. LEDs have negligible degradation, and remain usable past the 15 year (24/7 operation) mark. All the while consuming significantly less electricity and outputting much less heat.
In conclusion, I love LEDs because they are awesome.

Looking forward to your report Glenn, that's at least two of us at the moment just ordered stevesleds
Being is the U.S. you should not have to wait as long as I did for the courier to deliver them
If Jeff comes with a setup that I just open the plastic lid of the RSM250. Take the T5 bulbs. Screw there the setup with one wire (or 2 ) that I can pass through a new hole made in the hood. All without touching the original electric wiring of the RSM, then...... I want one.
Cheers and I will follow your instalation thread.
Daniel
Ps: unless Jeff wants to visit Boston and install his actual system in my hood, in 1-2 hours, as he claims. I wait him with a nice BQ and Samuel Adams beer !!!
This is a teaser pic - because I am tired and off to bed ... my new Steve's LEDs are installed up & running
Quick top down pic shimmer of my new leds - lots more to come... very excited !
Got my Typhoon controller programmed & working...
Can't wait to see sunset tonight and sunrise in the morn...
Typhoon controller... 2 hours sunrise starting at 7am & 2 hour sunset starting at 7pm
40% power to start when on maximum... for now .
Absolutely loving the looks ! Corals & even the colors of the fish are popping !
Power supply for the lights & Typhoon controller in my RSM cabinet.
