I’ve thought about xr15s… funny because I just sold a g6 pro. Problem with that is even used is be spending the same as two new reefi and would have a lot more cables and power bricks to hide
Reefis use a 320w power supply, I’ll post a photo of them when I get home. They are a robust piece of hardware.
I like my reefis because they use built in WiFi to broadcast the user interface to your device, pc, phone, tablet etc. the UI and settings are stored internal to the lights and do not rely on anything external to work, no cloud server, nothing. If Reefi ceased to exist you can still access the UI and control your lights as you always had.
Daniel Lu did a great job engineering them, he’s a chip guy from Washington state, Intel if I recall correctly. He continually puts out firmware updates for free to make everyone’s Reefi experience seamless and trouble free. You can go back through the firmware logs to see exactly what each update addresses. I sent him an email with a question about an issue I had with the latest update and he responded with the solution within 5 minutes, that’s someone who cares about their customers, no waiting until Monday morning, he responded immediately and had me back up and running smoothly in 1/2 hour. Ends up the latest firmware doesn’t recognize an off period and automatically tries to ramp the 10pm endpoint to the 7am warm up. The fix was to drop the first and last time periods to zero watts and problem solved.
FWIW I use the default SPS settings without any color tweaking and it’s good for me.
Of course they do custom acclimation, 24 hour time zone moon schedules, random cloud cover setting etc., and optional included 120 degree reflector. They really are nice lights, all with a 3 year warranty. I think the Reefi Uno 2.1 Pro is selling for about $550 these days. Daniel has no distribution network, no wholesalers, no warehouses, it’s all him so that’s how he keeps the cost down.
