SB Reef Light Pro 32 Timer Diode Swap

[DSmithZ28]

I was wondering if anyone has changed out diodes in the SB Reef Pro 32 Timer model? I had two of them lose a significant amount of par compared to the 2 new ones I have so I had to buy more drivers. While I’m changing those out I was thinking about changing out some white lights to UV and Blue. Has anyone done this and have any advice about which diodes to use and how many whites to swap out? Any good links I missed searching our information would be greatly appreciated.

Should be pretty much the same as any Chinese Black Box diode swaps.

Diy Changing Diodes On Black Box (Blackbox) Leds

If you are running the Evergrow D120 or D2040 "BlackBox" chinese LED lights, then you know they are PAR monsters and can grow coral. However, even the full spectrum versions could have their spectrums tailored a little. Too much warm white, not enough 420nm. No true UV (385nm). You can easily...

This is just the PCB board swap. I was wondering if anyone has changed out specific white diodes to other spectrum diodes and if so, some specifics on which ones.

Yea I know, point was that modding bb's is the same as w/ sbreefs. Plenty of people have done diode swaps w those kind of boards.

How would you make Ocean revive lights better?

Now that I have modified my lights so that they can be run from a controller and am comfortable taking them apart. I’m thinking about improving the spectrum. Below is the layout. If you where to move around the LED’s how would you change it and why? What about removing certain colors all...

What to change is more personal than functional

@Dana Riddle do you have any suggestions?

@Dana Riddle do you have any suggestions?

I performed a procedure when I was in Hawaii that examined the effects of spectrum on coral growth (Porites species). The light that had the most violet/blue produced the most growth, although an analysis showed differences among the different lights was not significant. Hence, it seems to boil down to personal preference. Now, with that said, I would build a light with some UV-A, plenty of violet/blue, and red light (that shouldn't shouldn't exceed 10-15% of the total. Some light around 730nm or so *might* relax Photosystem I (the electron acceptor) and prevent a damaging bottleneck of electrons in Photosystem II (this if light intensity is approaching photosaturation - something along the line of PAR values around 300-400 for many corals.) I'll post a link if you're interested in seeing the Hawaii light experiment.

SB reefbright led layout

Yes, the 395nm are tricky. I had issues with them browning out. I've since ran some experiments. My findings arent complete yet but I've made some interesting progression in successfully keeping 395nm without issues. I too used the SB layout but since I like using lenses, I found the disco to...

The orig. sbreef is pretty well populated.
Adding more blue/violet/deep blue/UV to the white channel is a matter of taste or PAR requirement.

Suppose since you would be doing some surgery anyways a few 720's (740's) in there doesn't hurt.

Wouldn't hurt to throw a few ambers (500nm) in there as well increasing parity to metal halide spectrums.

Effects of Different Spectra Generated by LEDs on Growth of the Stony Coral Porites lobata

Stony coral nubbins (tentatively identified as Porites lobata; see Figure 1) were exposed to light of the same intensity (128 µmolm²sec) but different spectra for 75 days. Growth rates were determined by weighing the fragments periodically with an analytical balance.

Photosynthetic Efficiencies of LEDs: Results of Short Term Exposure to LED Lights

Dana Riddle studies zooxanthallae exposed to varying intensities and colors of LEDs between 365nm (UV-A) and 657nm (red). The collected data sheds light on how different spectra affect photosynthesis and the Xanthophyll Cycle, helping us to better understand how corals use and respond to light.
