Does the delay apply to only Rev 5 or even Rev 4 unit ? I mean I would be more than happy with a Rev 4 eligible for future upgrades
Any news on Rev 5? Or what's happening with Rev 4?Sorry I've been silent folks - it's been a struggle lately getting things done in general
The short version is that I had to put Rev 5 on hold due to an issue with the new LED board design. Samples worked fine when we were initially developing the design, but once we ran a few production sets, something wasn't right. It has taken months to get answers from the manufacturer but I believe we have solved the issue, but it put up a huge red flag because if I needed to change the design, that could have cascaded down to changes on other parts so I had to slam on the brakes.
That mean production of the new heat sinks and plastic parts is on hold, and that is another issue because lead times on those parts have gone from a few weeks to months.
Rev 5 release date is pushing back to late summer at best, likely mid-fall. It sucks, but I'm making 1000% sure this version is done right and there are no surprises. The good news is that I've got access to an SLA 3D printer so all of my parts designs will now be fully vetted in house before going to the mold & die making stage. That also means I'll be able to show you better teasers pretty soon.
The LED board issue also has an impact on the quantity of available Rev 4 units as I was planning to start using the new LED boards in the ding/dent Rev 4 units. Instead, I am making as many units as I can using the old design. The problem with that is that 1) the driver chip I was using is no longer in production (after being a standby product for 30 years) and 2) I bought the last available reel of Luxeon Deep Red LEDs in the entire US and there won't be any more available until November. The new LED board uses a different brand LED so the supply chain is (knock on wood) not an issue.
Other good news is that I have part-time staff knocking out Rev 4 parts, I have a small supply of the current LED boards in hand (that also took several months longer than anticipated), and Rev 4 ding/dent units are going to finally start shipping soon.
But is an AC/DC converter needed (like for radions)? I assumed yes, that's why I asked what voltage.Universal voltage. Since amperage is dependent on voltage, I'll give you wattage: roughly 30-35W per board pair. The L2 is one pair, i.e. one board on each side of the algae screen (35W), L4 is 2 pairs (70W), L8 is 4 pairs (140W). Again that is rough, but it won't be more than 35W per pair of LED boards
Oh yeah, so I was wondering at what voltage do the LED work at? 24v like radions?LEDs only work on DC, so pretty much any LED fixture by rule will have an AC to DC conversion at some point. I don't know anything about Radions but my units have always come with a universal power supply. The only thing that might be needed is a plug adapter. Rev 5 units will use a power supply where the input cord can be changed (similar to a laptop power supply)
I just would like to know what is the voltage output of the power supply? I am basically unifying all my power supplies, with DIN rail industrial power supplies, and hardwiring all the equipment (something like this: https://www.reef2reef.com/threads/lasses-dream-build.246188/post-6475220). I am in list for your rev5, and I wanted to be prepared accounting for the Rev 5 lights, so that I can size my power supplies accordingly.It depends on the version. My first 2 versions work a constant current driver. The last 2 worked on a constant voltage power supply with on-board drivers (the LEDs are not driven directly by the power supply). Similarly I assume Radions work on a 24V power supply that internally is converted to a constant current as all LEDs operate based on drive current, not voltage.
