Just when I thought I knew the answers - along comes a pony question
. Since you'll have ponies I think the 110w would suffice; however, let's see what others think. We used to have par ratings on a 110w but I don't think they've resurfaced in this thread. That said - if I were in your position I would still get the 160w - just wouldn't run the 30w LEDs. Why? Resell potential and should I decide to give up the ponies I would have a fixture I could use on whatever I decided to do next. Hmm - where was that great advice when I bought my 110s I wouldn't necessarily say this is true at all. With all things, it depends on your setup but some things to keep in mind are
-2x110/160W units will be more expensive than one 170/230W comparable unit.
-Beneficial coverage will essentially be the same with 2 smaller units vs 1 larger as the dimensions indicate the 110/160 are exactly half the length of the larger units. True, you might be getting more LED's with 2 of the smaller units but 120 degree spread is 120 degrees of spread.
- 2 smaller units evenly spaced across a 4 foot tank will probably result in a dimmer center/corners vs having dark corners with 1 larger unit
- If you intend on keeping light sensitive corals below 12" or 15" of water, then it might be useful to have to the 30W LED's, potentially at the expense of the corals higher up.
- I would be more worried about those 30W LED's bleaching or browning out the corals over a period of time. We've seen bleaching/browning with the just 3Watters, the 30's worry me a bit. Not to mention while they're running, the color of the tank is not very pleasant to look at. So instead of running them all the time, they're cut them back to just a couple hours and then the rest of the photoperiod, only the 3w blue/white/purps are running. Now you have significantly fewer 3Watters running the majority of the day in comparison to the 110/170 models, since their quantities are cut back to make room for the 30W that are barely on.
-ex. You lose (4) white 3W Leds and gain (2)30W Leds when going from 110W to the 160W version, however this "upgrade" will cost a $140 per unit over the price of the 110 and better your chances to brown out or bleach, plus make it more difficult to keep the color of the tank visually appealing.
IMO, 30W LEDS are not the answer to penetrating deep water. Optics are.

GET OFF MY LAWN
I actually prefer no optics on my units / mounted close to the water. The 30W led's penetrate amazingly well & the spread / coverage is excellent.
Hi there.
I was about to build a diy led fixture controlled by a microcontroller, but now I'm thinking twice about building the fixture. But I would like to build the controller anyway.
Anyone off the current owners of this units have simple electronics knowladge?
If so, would be nice to have someone to try to read the output voltages of the controller for each channel int the multi pin connector that goes to the led fixture. The idea is to realize if they are providing simple DC voltages, or in form off PWM signals.
As a not dimmable fixture, I think that they are providing DC voltages directly, But I would like to be sure before think to buy one.
If anyone will try to do the measurements, be very carefull about shorting the pins. DO NOT put multiple pins from the connector in contact with the multimeter/osciloscope probe.
Waiting for your comments.

First of all, I don't have any electronic knowledge and I will never attempt what you described. The following is what I picked up from a post from another forum to address my question re change of PCB. I don't know if it answers your question about voltage.
"While comparing the system design, the PCB becomes modularized and standardized. Basically, the controller of Maxspect contains 1) micro-controller, 2) control panel, 3) 3 to 4 sets of constant current driver (the working voltage is either 60V or 100V). For G1: 1 & 3 are bundled/ soldered into one single logical PCB. For G2: the constant current drivers are still keeping in one single PCB. As a result, different models use different PCBs, it is too stupid!!! So, I expect in the coming design, it will separate the constant current drivers and add the dimming logic!"
It seems if Maxspect ever upgrades the fixtures to be dimmable, all we have to do is to switch the controller, correct?
Yes, thank you, that answers my question! 
Yes you're right, if they want, they can sell a new controller with dimmable function at least.
The led fixture setup, will never allow to do clouds passing simulation with only one fixture, however, with more than one fixture, and a diferent controller, you can do it.
My tank has 170cmx60x60, and I'll need two fixtures. I'll try for sure to simulate clouds.
But the more importante thing, is sunrise and sunset, and that, you can do with a single fixture, also as colour temperature control. You can also set the maximum power for the 30W leds channel to avoid that huge bright effect when they are on.
Thank you for your reply.

This thread is about providing information of Maxspect products in a non-biased and non-commercial way. There was some information and pictures re PAR readings of G2 160W in a real tank situation that were posted in the now deleted thread. I think that information is extremely useful for what we are discussing here. I have found those PAR readings and pictures in SFVR forum but am not sure if we can link or post those pictures here. I sure don't want to get into any trouble with the mods here. Any feedback from the mods would be appreciated.

I recently picked up a G1-160W model pretty cheap (since they are all but sold out). I would have preferred a G2, but the money just wasn't there.
This is an upgrade from a 96W PC fixture and the change is pretty epic. This tank is a 45g penta (basically a 2'x2'x2' cube with a 13in corner cut out of the front. I have no dim corners, even though the lights is only about 3 inches from the water.
96W PC
160W LED
I didn't get a programming manual, so that was tricky, but nothing I couldn't figure out.

Has anyone ordered the fixture with the Cree options? Just wondering what the surcharge was like.

Some PAR readings taken by a fellow reefer from a pair of G2 160W over a SPS dominating tank 40"X24"x24"
3” under water, under the 30w LED bulbs: 1481-1529 PAR.
6-8” under water, moved between two 30w LED bulbs: 576-590 PAR.
16” under water, near the center: 321-323 PAR.
22” under water, on the bottom - 236-238 PAR.

Just when I thought I knew the answers - along comes a pony question
Thanks. I'm going to keep with the 110w. The 160w adds the 2 30w leds but in exchange removes several of the 3w whites. If I'm not turning on those two whites I'd end up pretty blue. Plus, it's an extra $110 for lights I'm not using. I get your justification though on the resell. Should be good for what I'm doing. Even without pony's I'm not that big into the hard corals. I think the only thing I'd put in there without ponys would be a birdsnest or maybe a clam way up high. In either case though not 'enough' of them that I'd need the light lower in the tank to be able to handle them. Thanks!

can someone pm me on a vendor, i have one in mind but i dont know if anyone has ordered from them. i know of 3 companys but i dont want to post the link on here so thread can live on. im going to be adding 3 110w g2's on my 75g tank, mounted on top of tank, my buddy brought over 2 120w panels from a different hk brand but my tank was shadowed over the middle and corners, since my rock work is about 2/3rds of my tank. i dont want to hear my landlord about having them mounted off the walls, so i think 3 110w g2's will do me justice. does anyone see any problems forcoming. will 3 110's fit on 48 1/4" spread with feet on light. my math came out to 47.22" of light with out feet. the only issue i see it the tabs in front of the legs but i think i can stagger them such as: Lay the middle one on 1st the lay the outside right one leg on top/front of middle middle legs and same for left fixture. any advice would be great.
i posted a pic of my setup with 6x54w tek light running 3yrs everything grown from frags under this t5 fixture.
anyone have a good way of acclimating the new light. i was thinking of lighting up the photo period and maybe leaving middle fixture off until the 2 others are are going full strength.
thanks in advance

Purveyor of Cool
My dual 110w units showed up today. They turn on, but one refuses to respond to control inputs on the driver unit. Plug it in and it's just "on". The second works fine.
I am testing them over a 75g tank, and the color is good. They're not as bright as the 4x T5s that I usually run over the tank (21" deep). I think they'll be fine over the 16" tank I plan to use them on. The shimmer is nice and HOLY COW the color is cool under the blue LEDs only. I would recommend the 160w (or more) for a 21" deep tank though...
