I have done some research on purchasing LED Fixtures for reef tanks. I have found a fixture that exceeded the output of other fixtures being offered and meets my requirements. I am offering a purchase for anyone interested in upgrading to or buying a LED fixture.
Some fixtures sold in the local marked have been found to be missing a critical part to the performance of the fixture… namely Heatsinks. The fixtures of this purchase HAVE integrated heatsinks that cover the entire LED bulb assembly. Heatsinks are a must in a led fixture to keep heat from the LED bulbs. Heat is the primary cause of failure in an LED. Also there are vents on all four sides (many I have seen only have vents on two sides) which improves air flow over the heatsinks.
The 120W fixture purchased in the last buy is 16" long x 8.5" wide and 3.0" high. The LED panel window is 12" x 4.75".
This is how I mounted fixtures over my 60 x 30 x 24 180 inwall. I used Light lifters (avail for $19 comes with a pair of lifters that hold 22lbs. 120 fixture is 10 lbs)
One thing I like about this manufaturer is they are willing to offer white lights from 4500K to 20000K and Blues from 440-470nm.
There are other spectrums available :red620nm-660nm;orange610-615nm;yellow:585-595nm;green500-530nm;UV380-440nm;IR730-850nm most of which do not concern saltwater aquarium usage.
My choice was to go with 14000k and 453nm. 16000k will give a slightly whiter look
Also they offered options of ratio mixes and I chose as close to a 1:1 as possible. 63 whites and 56 blues arranged as in picture.
There is a timer option available for $25 extra... the timer is pretty good as you can set on off times in eight different modes:
you could have all come on at the same time and off at the same time
you could have blues come on earlier and turn off later than whites.
you can have different times on different days of the week
PAR READINGS??? After my sample unit arrived I set it up over my tank and took some readings... I am Very impressed as th PAR reading are much Higher that some other 120w fixtures that are out there. And the spread was very good as you san see in my readings. I did measurements with White only, Blue only, and then with both. I also did a spread reading to the sides with both colors on at 6", 9", 12", 15", 18" and 20" in water. The lamp assembly is two inches above the water. Compare the following ( as measured by laffingcrow in another thread) to MH 250W @ 11" depth= 150 PAR @ sand bed 20"depth = 100 PAR ;T5s 2-wt/2bl 11" = 100 PAR @ sand bed 20" depth 50 PAR
The manufacturers seller has continued the discount price from the last purchase for the described unit (120W 63-14000k (or 16000K) whites and 56-453nm blues arranged as in picture) and they are currently available for $245 (Shipping included). This is a corded model without a timer.
A Timer option is $25 additional per unit.
Standard case comes in white and black cases are $10 extra per unit.
