Hi all. I'm looking to purchase a bunch of lights, but confused as there seems to be a lot of pages with the same specs, but different prices. For example the following are both 5m LED strip 12v ws2811 30 pcs/m, SMD5050, waterproof in silicon tube. The only difference is the black/white pcb. There's just under $5 a difference per 5m. What else if different? https://www.aliexpress.com/item/32493719302.html https://www.aliexpress.com/item/568458133.html Same with bullet & square nodes. There's so many that look the same, I'm not sure which to choose. I'm looking for recommendations and links to products others have purchased and been happy with for strip, bullet & square nodes. Are the Ray Wu in spreadsheet form links still a good place to start? Not sure when the last time they were updated. Cheers.
