I will be upgrading the 29 biocube to LED from Rapidled. I will only be keeping LPS in there and I can't decide to go for the 12 or 24 LED's. What do yo guys think? I know that light spread is going to be somewhat of an issue with only 12 LED's. I was thinking to get the 80 optics.

I think you could do 12. Remember to space the lights and corals properly. I would do SPS though unless it was directly uder light and high up. LPS and softies should be OK.

 

 

Thank You. I will be going with the 14 LEDs. Waiting on Uncle Sam for some tax money. :rollface:

What heatsink are you using? What ratio of LED's do you plan to use, and which LED's, and which drivers?

I will prob get a 23"x 4" heatsink from rapidled. I am getting the dimmable driver and I am still deciding if I am doing 8/6 or 7/7 LED's. XP-G R5 for the white and XR-E for the royal blue.

I would get 8 blue and 6 white. My setup is 12 blue and 12 white with the xp-g and xr-e. I did not get dimmable, and I wish mine looked more blue... If you do 50/50 it will look crisp white. There won't be much blue tint at all. With LPS you will get much more glow with 8/6 imo.

 

Here is a pick of mine with both whites and blues.

Whites only

Cool, thanks for the pictures. I can see the difference and I do like the blue look a little better.

Are you planning on using 1 driver? I would suggest not mixing XP-G LEDs with XR-E LEDs if you are using 1 driver. It's a constant current source and if you drive your LEDs too hard for the XP-Gs, you'll fry the XR-Es. If you drive the LEDs for the XR-Es, you'll underdrive the XP-Gs....not as bad as frying LEDs but won't be as bright as it could be. XP-Gs are rated at 1500mA max. XR-Es are rated at 1000mA max so you will probably drive it around 700mA....half of what the XP-Gs are rated for. The XP-Gs would be dimmer than its full potential.

 

Now...if you are using 2 drivers, that' a different story.

Good call. I would skip the xp-g's, and just use cool white xr-e's that are driven at 700. Make sure you do not drive more than 14 XR-E LED's on the lpc-60-48d....
