chinese led lights

[A_CoupleClowns]

I like my Nova with optics better than a d120 without optics. 48 vs 55 leds is not noticeable.

If you don't have an Apex already, its not very efficient to pay $500 for it, and then another $400 for the light. All you would be missing with the Evergrow's are automatic dimming and moonlights.

If you really want automatic dimming and moonlights, the Twilight lights with a built in controller are a nice option.

Yeah I thought the apex was cheaper and did more than it does lol...

I don't even think I need the moonlights and autodimming also isn't a big deal. I'm coming from a 4 bulb t5ho so these lights should be a huge upgrade as is.

Now that I'm thinking about it even if the a4's don't fully cover the 75g I could buy a third light for cheaper than the apex setup.

I would try the twilights but I figure if the dimmer knob goes out on the a4 I can repair that, if the twilight control panel goes bad that will be much trickier to repair.

They make the Nova in 3 sizes, A4, A6, and A8. The A8 is twice the size of the A4's, with 96 leds.

Cmantis, do you have a picture of what your light looks like over your tank with all the different colors you have?

I figured two a4's will work around the center brace better, and hopefully result in a little better coverage.

But maybe that a8 is pretty cheap I'm gonna look into that.

Can someone please list the K or nm of what the LED's come in for reference.

I want to order a mix of whites and others but i want to know what I'm talking about so I can get a full spectrum. Like, do I want cool or warm white...got me. hehe

Cool white = ?K
Neutral white = ?K
Warm white = ?K
Royal Blue = ?nm
Blue = ?nm
Violet = ?nm
red = ?nm
Orange = ?nm
Green = ?nm
UV = ?nm

Thanks!

Question on the dimmers for these. I got mine a few days ago and when playing with the dimmer it dosent seem to get any brighter after the halfway point (specifically on the blues). Is it just not visually brighter? Or could there be something wrong with the dimmer?

Yeah that doesn't sound right? Which model?

Can anyone confirm there's gets brighter after halfway?

There's nothing wrong. It probably does get ever so slightly brighter up to 65%, and then hits max. You'll notice that under 50%, any minute adjustment makes a difference.

Think of a volume knob on a stereo. You get distortion once you turn the knob past 65% or so, or whatever the max the speaker can handle. Instead of "distorting" at max here, it just doesn't get any brighter.

These auto dimming models do they ramp up from nothing or do they come on and just ramp up a little

They ramp all the way, from 0 to 100%.

These are nice new lights I was just notified of too. These are somewhat comparable to an AI SOL without a controller or extra features.

I have a 40B with a tall canopy that I want to stay in-closed that has 2 fans pull air out on the backside, I would like to get 2 fixtures as I don't really want any shading and like a bluer look and wouldn't mind some UV. I do not want to do any soldering and would prefer pre-built plug and play fixtures with some fans blowing air. What fixture do you guys suggest? I have read pretty much all 124 pages of this thread and have seen many opinions and just wanted to see what yall thought would be good for mine. Thank you.

I don't think you need two. One should be enough. I have two d120's and two 40 breeders. I won't have water in them until next week but if you still want then I can post pictures.

Pictures always help, I just have heard the max is around 24" and obvi the 40B is 36" would rather do overkill than under and have shading, plus if I ever upgrade could always use them.

Alright guys im about to order 2 a4s for my 90 gallon tank! My question is do i need optics? The tank is 24 inches deep standard for a 90 gallon. I know if it was deeper i would definitely need optics but do i need optics for a 90? I am REALLY trying to avoid the spotlight effect because i hate the look. Thanks for any replys in advance!

How much are the auto dimming lights

Thanks. Just wasnt sure

I have a 60gal 36x24x18 and I have one D120 right now with no lenses. It is 8" above the tank with a brace in the middle. Light spread is fine and reaches where it needs to be. No shadows that I can detect or tell. Right now I have a few fish and corals and still working on the tank. Mostly mushrooms, polyps, zoas and everything has shown improvement.
