Are there any of these Chinese led's that are controllable by apex? Using a 0-10v signal
Are there any of these Chinese led's that are controllable by apex? Using a 0-10v signal
There are three wires running from the dimmer knob circuit board to the LED driver (driver is labeled 0-10v by the way).
I just tested the lines to see which ones showed a voltage with my multimeter (middle and furthest away from the board) and then hooked these up to a spliced RJ-45 cord I had laying around from the days before wireless.
The hardest part was finding out the type of RJ-45 cord I was using had a few of the wires switched around (this is common for these cords).
Suppliers could save themselves a few bucks by giving those of us with controllers one RJ-45 port and eliminating the dimmer knobs.
hi all, im building a 6ft long bowfront. will 3 of these pre-made units work being that there are difrent widths in the tank, or do i need to build a DIY kit where i can make diferent sized heat sinks. like 2 more narrow for the sides, and one a lot wider for the middle of the tank? just too much info in all these posts to figure out... i've got a medical degree, not an engineering
Quick optics question on the D120 - going to hang one over a 60 gallon 24x24x24 cube - which optics should I choose?
Thanks!
Which 3 fixtures are you thinking of getting and what is the depth & width of the tank? Depending on your bracing, high how you want to hang them (canopy?), budget, physical look you want (IT series look nicer if exposed "“ no canopy) and what you are trying to keep a combination of fixtures should work. For example: two 16" (D120 or IT 2040's) and one IT2080 with mostly 120* angle optics in the middle 60 of its 99 LEDs would give great lighting. Or if you don't need that much light/PAR a third 16" or a 24" unit centered with 120* optics would give you more light spread to cover the wider part of the tank. I would assume that the end units would be all 90* optics except Red & Green LEDs (120* optics) to minimize the disco effect you see mentioned in these threads for whichever fixture you chose. Both direct group buys with EverGrow and the Reef Central ones offer full spectrum custom layouts which includes different optics options. Try posting your tank dimensions and what you want to keep and somebody with that same tank can probably make more specific recommendations and maybe even pictures. If you can find someone in your area with any tank it is always a good idea to see the fixtures in operation before you buy.
Its easy to remove the 90º lens to the it2080?, because I only have 3" above water surface to place the screen. My tank is 24" deep.Can I place the it2080 with the optics with this height of 3"?
the "middle" of the sides are 22 inches wide, the middle of the tank is 26, it is 28 inches deep. ive got a canopy so dont care about looks. never had a SPS tank, but wouldnt mid trying it on this one, so i guess all types of corals.
I have 90deg optics over my 60 gal cube.
Seems to work fine
Whew, long thread. After looking through here, and other websites, I am trying to figure out the correct led lighting.
My tank is a 30 gallon, but is a cube. 20 inches deep, and 20x18 L and W.
I kind of understand the way they work but do not understand it well enough to build my own. Can someone give me a little insight about what would work best for this setup? I know about cree vs. japanese lighting, just don't know which would be better for a deep 30 gallon.
Anyone have some useful insight on what would work best for this? Japanese (bridgelux 120 watt) are cheaper here but only use 1 watt maxed out per bulb. Any help would be greatly appreciated.
Not sure what Bridgelux system your talking about, but the most popular fixtures use 3 watt LEDs.
Get one D120 or Photon 16 with standard or custom layout and 90 degree or 120 degree optics. Hang the unit 6-10" above water surface.
here are the bridgelux specs
120 Watt dimmable REEF aquarium fixture with Bridgelux LED
2 dimmers on the fixture, one for blue/violet and one for white/colors. Total LED: 55 (3 watts per LED) = 120Watt- LEDs are running at approx 2.2watts each to prolong life of each LED
31 Royal Blue bulbs / 4 warm white / 4 Neutral White / 6 cool white / 5 violet / 2cyan / / 2 red.
Duel Power switch and cord (1 cord/switch for white and colors and one cord/switch for blue LEDs and 2 violet
Color: White LED 12,000 -14,000K, 450nm Royal Blue 420nm Violet+ 630nm Red+520nm Cyan
Working Current 630mA
Lifespan: 50,000 + hours
Size of each fixture: 15.75in x 7.8in x 2.5 in
not sure if it's 1 watt led's though....
what ridetheducati was stating what that he doesn't know which bridgelux fixture you're referring to because you mention 1w LEDs being used. the bridgelux fixtures in this thread are 3w, per your description above typically run at just a bit shy.
Yep, sorry that is confusing on my part. I do not know the name of the bridgelux fixture, it is someone who is selling on Craigslist and doesn't name the fixture. It looks professional but might be privately made. It Has 3 fans and is hangable. Don't know how to post pictures.
It has the 3 watts per bulb but turned down to 2 watts. Looks like its about 10 x 8 or so inches. Will these lights bleach corals on my 30 cube?
