Custom Order LED Fixture with 400 watt MH Brightness, and PAR, 6.5 to 14 Kelvin, Moon Lights and 60k hours life!

WELCOME to WWW.LEDREEFLIGHTS.COM

This is a video clip of the center left portion at 24" depth in a 4' by 36" deep tank with 1 CJB. The video is taken at 40,000 Kelvin full light output. Stony corals previously occupying places higher in the tank (empty spaces in the picture) had to be removed due to the light levels when the CJB was installed for videoing. The video takes about 60 seconds to download on a high speed connection.

LED Lights are the future and the future is here now at $500! The CJB produces the same PAR output as a 250 watt MH.

LEDs and Metal Halides:

We have taken research results for 250 watt MHs with polished reflectors and produced an LED based light that produces better results and flexibility at 250 Watts! We can prove our results by comparing the research that Sanjay Joshi publishes (http://www.advancedaquarist.com/issues/may2005/feature.html) on 250 watt MHs without reflectors against the PAR readings of the CJB. The highest PPFD (PAR) reading Mr. Joshi found in this study was 171 PPFD .: the CJB produces on average 200 to 300 PAR with areas reaching 700 to 800 PAR.

When Mr. Joshi added reflectors (http://www.advancedaquarist.com/issues/july2003/feature.htm) he found 200 to 300 PPFD (PAR) readings on areas of light measuring 14" by 18". The CJB produces the same 200 to 300 PAR readings over an area of 17" by 18". If you wonder if PPFD means the same thing as PAR, see Mr. Joshi's explanation 4. What is PPFD? at http://www.manhattanreefs.com/lighting.

Keep in mind multiple CJBs can be placed next to each other and raise overall PAR level with no heat problems. Three 250 watt MHs next to each other will create a heat problem.

The CJB Versus Other LED Units:

Other LED MANUFACTURERS use focusing lenses to narrow the beam of light and achieve high PAR output. We do not! We take a "flood" versus a "spot light" approach with a higher level of total light output. The CJB produces a 17" by 24" lighted area: we far exceed the 8" by 12" light coverage provided by others. The CJB PAR table is on the Specifications page and competitor results are found in articles at the Advanced Aquariast on-line magazine: October 2007 issue!

If you grow stony and soft corals under 250 watt Metal Halides, then the CJB will produce better results as stated by our customers. According to the data presented by respected researcher Dana Riddle, stony corals need about 250 PAR to thrive. Corals needing extreme light require 645 PAR, but those are very few. Acropora, believed to need high levels of light, actually saturates at 250 PAR. 650 PAR is within the CJB capabilities, as is 250 PAR : so no problems with keeping a wide range of corals! The CJB is recommend for 36" deep tanks: the top depth of 24 to 30" for stony corals and the remainder for softs. Some hobbyists state they grow hard corals all the way down at 36".

Why Buy A CJB?

You save money, get a better and stable spectrum, and get a better product when you buy the CJB. You buy the light output you need, a lower electric bill, no new bulb replacement costs, no replacement ballasts, no added cooling costs, and no change in spectrum or intensity until after 6.5 years of use: all of this at a total lower cost than MH or Fluorescents! Based on your electricity rate, payback is in 18 to 24 months!

Some are hesitant about LED technology: Compare!

It has been our experience that corals previously grown under 250 watt MHs have to be gradually introduced to our lights. In many instances, when corals were introduced too quickly, the corals shriveled, and turn black within 45 seconds to three minutes! The video on the home page had various corals on the upper levels removed due to the burning accident. Skeptical? Try the unit - remember you can test the CJB for 10 days.

We can now build LED units that produce the Brightness and more PAR than a 400 watt Metal Halide. The blinding brightness and the PAR will be there! Give a call if you have an interest.
