Up close picture. These are much different than the traditional black box led. Cathode and anode are not clearly visible. Must be on board underneath.

Jugging from the globs of solder (?) my guess is that this is an assembly done by an automated process. SMD, yes, is my best estimation.

Keep me updated I wanted to swap the lights and even bought he LEDs but decided it wasn't possible
First it can be done but a short list of problems
1)Which companies diodes and/or "footprint"?
BTW anode and cathode points are visible in that photo.
2)Getting the above esp. if a OMC type diode.
3) Removal is fairly easy w/ a hot air rework station
4)same w/ reflowing new diodes
5)electric frypans can be used for boards that will fit in them.
6)need the right solder.
It's not easy but it's possible.
you can always go full gonzo.. ;

Good thing:
Hopefully they are better diodes than the old "Bridgelux "egg" type units..

They seem to be very cheap when removing lenses on all of them some of the LEDs cracked or chipped but still work.First it can be done but a short list of problems

Here's a diode layout for them:
Could use some UV, but that's debatable. I'd say if they are working for you and it sounds like some of your LEDs are at the end of their life span due to the discoloration, they can be replaced easily.

Summary/Overview: Over the last few years, we have seen more beginner and moderate reefers becoming more and more inclined to attempt DIY projects. Anything from building a custom roller mat or an algae turf scrubber to attempting a stand build using two-by wood. With LED’s becoming more...

[emoji106] Thanks flippers for all your work on this. More work for us all on these SMD chips, should be worth it in the end.
I'm having a hard time with some of these sellers that dont speak good english. They dont understand my questions about which chips there lights have.

Your welcome, but it's a community effort. Tons of people have been toying with these since black boxes came on the market. Im, as others are just piggy backing on them.
You can start by measuring the package. i.e the little ceramic square..
smd5050's are 5x5mm ect..
I'll guess as to something like these.. ;)
https://www.ledlight-components.com...m-white-and-white-light-emitting-diodes.html#
3.45x3.45mm
footprint looks fairly generic..
hopefully the "lumen rating" is as good (though not great) as the above..
90L/ watt..ish
Getting to be pretty standard nowadays.

Exactly, then it's the hunt for the spectrum we want. Replacing them shouldn't be too hard. May take some thinking to get there.

Maybe @Dana Riddle can chime in on this as I haven't heard much of anything spoken on this subject. At least in the hobby. LED's will degrade. They may light close to the manufacturers claims of hours of use before they "burn out", but there will be a decrease in intensity and will color shift.
This is VERY important to us in the hobby, not so much in household lighting.
LED's degrade very slowly, so slow that we don't notice the decrease in intensity and color shift. Our corals will adjust to this slowly over time, to a point. This all has to do with heat and its effects on diodes. Cracks, delamination and heat effects on the phosphor coatings placed on the surface of these chips to achieve the color.
THIS HAPPENS TO ALL REEF LED FIXTURES. HIGH-END TO CHEAP FIXTURES!
With anything we buy, more expensive manufacturers of fixtures may use better manufacturing techniques and materials, but in time they will loose intensity and experience color shift. It's just going to happen.
Manufacturers of these fixtures, especially high end/expensive, regularly release "next gen" models in hopes that you will upgrade to them. As they don't sell replacement parts, led PCB boards, led diodes, drivers......etc. We've all seen this where owners will sell their "last gen" fixtures to help buy the "next gen" fixtures. Anyway, you get the picture.
Refreshing a PCB board with new leds, say every couple years will keep your corals happy and save you money in the long run!

Anyone know if all the units are coming in SMD fashion now? I was about to buy four because of the ease of swapping LEDs and replacing parts, but need to find something else if so. Not enough time in life right now for me to try to reflow stuff.

Don't know about the date of manufacture switch. To early in the game yet. I would think any made in 2018 would be okay. Just guessing.
The other option would be to buy the SBreeflight PCB boards. They would have upgraded led layouts.

I just saw this on Amazon. They now show the chips as SMD.
Can you link this for me? I am interested as it also says mixed view angles of 90 and 120. I have the new lights and mine only had 90 degree lenses.

I can't open my boxes now to measure them but it looks to be about 3.25mm or smaller as the lenses were covering the lights and were around them because when I used the twisting motion to get the lenses off I broke some of the LEDs.
