Approved Maxspect LED Fixtures Group Buy

[Baja170]

Thank you for the info guys, looking forward to cooler light fixtures!!

One last question. Which is best for a Marineland 93G Cube that is 30x30x24? I am going to consolidate 2 HQI Cubes and aBioCube into it. Mixture of LPS and SPS and softies.

I know someone mentioned that you can swap one colored led to another. But are they driven at different optimal current? ie the white leds are driven at higher current than the blue. If that's the case, switching them from one color to another won't do you any good.

They're mostly 3W except for the larger 15W or 30W.
So the 3W's should be swappable.

I know they are all 3W bulbs. Even so, their optimum currents are different. However, if the maxspect power supply use the same current for both white and blue leds, there'll be no issues with swapping. I hope that's the case.

The 3W LED's are about 3.3V each so it would be driving close to 1A to make it 3W

Thanks Ming. I understand everything you said. But I am reading between the lines. If you read the DIY led thread in another site, people are driving the 3W white and 3W leds under different current according to their specs. (eg. 1000mA vs 700mA) So if you swap the white to blue and the driver is driving the blue at 1000mA instead, the results might not be the same or desirable. I am just speculating. I just don't know whether the drivers in the maxspects apply the same current to both bulbs. Having said all these, even they are different in current, it might not make any difference to an average user like us.

Got the G2 170 from NYReefNoob and it will work GREAT on our 150 FOWLR aggressive tank.

Definitely makes me wonder how a 110 and a 160 would be on a 93G 30x30x24 Cube that will house sps, lps and maybe a few softies in some shade if there is any.

This is the new G2 160W with cree XP-G that I want.

Very interesting...

Is this an option for us on this GB?

 

[bigyankfan]

I am asking if this can be ordered as part of the GB.

Jonathan,

Keep your fingers crossed.

Can't wait to hear about the 160 with cree led. The answer will definitely make a difference in my order. Thank you Eric for finding out.

I just noticed that the XP-G LEDS used here are R3 instead of R5. The R5 has a higher lumen (139 vs 122) and that's what most of the leds online stores have. Either way, I am OK with it.

I believe most people drive the XPG's closer to 1A.. ratio's close enough though

R3 305-325 lm @ 1A
R5 348-370 lm @ 1A


If you wanted to risk burning the LED's out...

R3 406-433 lm @ 1.5A
R5 463-493 lm @ 1.5A

I know. The numbers I quoted are lumens/watt for the purpose of comparison. You can drive them which ever way you want.

We are getting down to the wire here any word on the Cree 160?

 

[bigyankfan]

Yes, I got a reply - the Cree version of G2-160w is also available in this GB, it'll be US$700 shipped.

Holy crap 190 more for the Cree LED version...

Is anybody in the know available to help us LED noobs know if it is worth it for the Cree upgrade? Please PM if you don't want to post in the thread, I will not post what you PM. Thank you in advance.
