Agreed, the 110's are fine on a shallow tank, but not so great on something over 20" or so deep. I have dual 110's and would go with 160's ... they just weren't enough light when I put them over my 75.

On thing to mention / as I previously stated. I have been cutting the usage of my 30w leds down to see how my SPS responds. So far, cutting them down to 5 hours from 8.5 has shown no ill effects at all. However this has only been for a tad less than a week. I am going to go another 2 + weeks and if all is great, I will cut their usage down to 2 hours & increase the time of the 3w white leds to take their place.
I am doing this as I had no problems growing sps even near the bottom of my 24" deep tank with 150w halides long ago with crappy reflectors. So I am stating to think many of us are giving corals far more light than they require. More output does not always equal better or more growth so I want to experiment and also watch carefully what the corals do color wise.
Anyways, just some of my random thoughts.
Current light schedule...
11am - 9pm 3W blues on = 10 hours
11:30am - 4pm 30W white on = 5
4pm - 8pm 3w white on = 4 hours
Next proposed light schedule to start on the 26th of this month...
11am - 9pm 3W blues on = 10 hours
11:30am - 1:30pm 30W white on = 2
1:30pm - 8pm 3w white on = 6.5 hours

Even though it has been 5, well almost 6 days, one of my corals seems to be coloring up better, but this could be my imagination. Time will tell.

I do not think the plastic is acrylic as stated, it looks to be some sort of lexan from the way it feels "I deal a lot with lexan on other projects" Also others besides myself have noticed the "material" deforming under the heat of the 30w leds and were posting about it in the original thread. This is not new info, others besides myself have documented this.
I just looked at both of my fixtures, and on both, the material is sagging considerably on each side under the 30W units. In the cooler center, the material is the same as it was new and practically touching the mirrored plexi or whatever it is.
Just wanted to point that out. Did not argue that lexan or acrylic were not better when it comes to light transmission if the panel is not warped from heat, however my panels are and others have had the issue. To note, the panels have not discolored at all from heat or bubbled, they simply are sagging / deformed. I am simply pointing out that under the heat of the 30w units, glass, specifically low iron like starphire could be a better choice as a replacement.

So, what are the differences in Maxspect Fixtures Semi LED vs Cree LED? Price & LED color specifically.
I tried going to Fish Street, but I got tongue tied & brain scrambled trying to read the broken English.
Garage - How has your QC experience been with Maxspect Fixture? I recall you have an issue almost immediately???

here is what I got:
==========================
"""How can I order Maxspect LED fixture with CREE leds? How much it will cost for the 170W with CREES and how much it will cost for 230W with CREES?
Please, let me know. Thank You."""
==========================
"""Hi
Maxspect is only have 6700K for Cree, it ony can using in freshwater only
Thanks

I ordered new stainless steel cables through GripLock. They were very nice. I will leave the stock pass through connector and wire in place there but I went ahead and picked up new "ceiling" connections just to be on the safe side; the terminal on the Griplock wire looks to be more substantial that the one on the provided cable. .

+1 I like the Griplock kit very much. It's very well built, provides 10' of drop and the slider functions smoothly.

a couple questions for all... I have read the thread front to back, great thread!
Is there a huge difference in g1's compared to g2's besides cooling and the ease of removal of led's on the g2's?
I am contiplating going with the g1's off ebay do to the shipping cost of the g2's, I mocked up a fake "cart" at fish street and 4 units shipped to the us is $490!!!! seriously....?!!! $490 for shipping, am I missing something or is there somewhere else to buy g2's and not pay that for shipping without raising the cost of the unit?

what are the differences between the crees and the normal LEDs that the g2 comes with?
I am really considers jumping in the maxspect club but I came accross a statement in another thread that has me concerned"
fishguy23 wrote:im a bit iffy about the 30 watt bulbs one quite a few of the us forums they talk about the fact that because they are so powerful for an led there life is alot shorter.
15-18% a year decay compared to 1W 5-8% (whites - blues decay approx 3%).
So roughly the 30W will degrade to the level of the 110W (60% of 160W) in approximately 2.5 years. At that rate, replacement every 18 months would be about the go, I think.
At least Maxspect are honest about their LED lifespans, compared to the others' too-good-to-be-true claims of **lasts 50,000 hours!!!! Never need replacing!!!**"
Is this true, have we really not fully understand how long LED will last for useful Par. I know that when T5's came out every one was stating they we good for 2 years at least before needing to be replaced and now that has change back to 10-12 months. Just like a metal halide will not nessarily stop firing after a year but the general thought is to replace them every 12 monthish. I am just concerning about dropping this kind of money even on a more affordible LED fixture to only find out I need to be replacing LEDs every year and at what cost.

Trueperc, I understand your concern. I was too before I decided to purchase my 230W. Here is some info for you to factor in your purchasing decision.
Maxspect's bulb replacement recommendation was based on the bulb operating 10 hours a day, at room temp of 28-30C (82-86F), and heatsink temp around 50C (122F). I doubt many homes with reef tanks in North America will have such a high room temp. When my 230W is fully on, the heatsink temp is about 40C.
So if your room temp is around 25C and your heatsink temp is around 40C and you run your light shorter than 10 hrs/day, the life span of the 30W LED bulbs will be signficantly longer than the 18 months stated by Maxspect.

Hi guys, I couldn't read the entire thread but wanted to ask if someone has had any luck finding a lens that fits the semiLEDs? I bought a few LEDs for a DIY retro (mostly to test these LEDs) and the reflectors I have actually fits the LEDs but when they are wired its another story. The wires won't let the optics to fit in place and needs to be glued.
