I'm doing a small project at home with 5meter LED strips ws2801 & 5050smd / 60 per meter. The total length of the project would be 25 meter so 5 strips in total and thus 1500 LEDs. The controller would be a raspberry using it's SPI. The idea is to use the 74AHCT126 for level shifting. The data & clk would be connected from one strip to another so from data-bus point of view it would be one large 25 meter strip. For power however I would inject roughly every 5 meter. The main goal is actually to have constant and dimmable light. The fact that every LED is 'addressable' would be an extra. So I'm not after anything fast but it should at least be able "to snake". For ex, the effects shown here https://www.youtube.com/watch?v=nJcTPrprZEQ is something that should at least be possible. As for the power supply I'm in need of something that is switched, 5v output, at least 200watt and ip67. Not many candidates. I found this on aliexpress https://nl.aliexpress.com/item/32872402391.html
As I have not much experience with this I would want to ask if this will work with said components? Any tips or ideas are also more than welcome.
