Just to clarify that these units have no controller so you can dim the LEDs with a controller like an Apex. You CAN MANUALLY DIM the blue and DIM the white separately with the knob on top.
Since there is an AC plug for white and another AC plug for blues you can have you blues come on first then whites later on your Apex, timer, etc. You just can not dim them automatically. Just manually. |

Thanks for that, I was thinking some didn't quite understand. The question I'm still asking is if they can be modified to have independent dimming and programming. If anyone has a link to a how too that would be cool.

This LED lights are legally considered portable luminaries, a plug-in lamp. In order for an insurance company to deny coverage they will HAVE TO PROVE you voluntarily connected the lights to the home circuit in a wrongfully and criminal manner with the intent of causing fire or cause injury. As a side note there are no aquarium fixtures CSA/UL approved. In order for that to happen they would carry the specification CSA for damp/wet and rated and listed as such in the directory. If a MH has CSA is NOT for use with your aquarium or near water. The only wet CSA/UL I've seen so fr was for the lights on boats. And your T5 fixture for example, it is not CSA/UL approved for marine aquarium use. The information I posted previously is from an electrician running a company for 35 years... |

link for converting chinese black boxes with knob dimmers to work with the reefkeeper ALC module, I would assume a similar mod can be done for making it work with an Apex. |

I have a 65 gallon 36x18x24 tank that I want to change from T5s. It will be primarily softies. Would the 165wt unit give me enough spread or should I go for the wider 300wt unit?

Get two of the small ones or one larger one. A single 165 watt will be way too small

Thank you for the feedback Bpb and paullondon. The light spread looks good in the picture. Will likely just go for the 300wt unit then. Good thread here.

Thinking of going with a 3 pack of the 165w for my 120 (4x2x2). Softies, lps and an rbta. Think that gives me the coverage I need? Thanks all.

Sorry, but also how far off the water should I mount them? Thanks

I don't have the first hand experience but if your tank is only 4' I think a 2 pack would be sufficient.

Since the measurements posted at the star of this topic were:
"My light is 18" off the surface of the water. 12 inch deep tank. (Frag tank) . Full blast both blue and white I was getting 400 par at the surface and 200 par 12 inches down. Half power I was getting 250 par at the surface and 125 at the bottom (12" deep)" I placed my lights on chandelier chains on brackets (see pic above) so I can easily move them up and down. The lowest I can set them is 10" above water surface and the highest is 29"-30" above water surface. This is sufficient to successfully keep most SPS and LPS |

Whats the length on the 300w unit? Would two be ok on a 265 (82x24X30) if i expect some shadowing? Or should I go with 3 165w units? Im worried about the 30inch depth.

Mars Aqua Chinese LED review (Ebay)
Quote:
Without any first hand experience, basically I just peaked at the add, they appear to be similar units with a different name pasted on to me... What are the dimensions of your 40g? (Just looked up the dims and one unit will be fine) I would try to research the customer support available from that company (if any). For the extra $25 for the Mars unit and some semblance of support and US warehouse for replacement, and support I would spend the extra. That being said the unit you listed does ship from California... |

Thanks for the response! I was really wondering if the wattage difference (120 vs 165) would really make a difference in a 40 gallon tank.

Mars Aqua Chinese LED review (Ebay)
The 165 w is actually an over rating.. 55 3w LEDs in both fixtures. Rated 165w but actual output is only about 120w on the Mars units also. These are Chinese "black box" units and basically the same unit rebranded.
