意大利采购需求：LED、LED封装、发光二极管、高效率LED、LED光源、车用LED

I'm reaching out to explore alternatives for a specific LED component we currently use. We need a reliable 3535 LED that meets certain criteria, specifically with a Color Rendering Index (CRI) greater than 80 and a color temperature around 4000K. It's essential that the efficiency is high, ideally around 150 lm/W or even better if possible, as we're looking to maintain quality in our products. Additionally, could you provide information on where we can purchase these LEDs? We typically place orders in quantities of 1000 to 2000 pieces at a time. Your assistance in identifying a suitable replacement would be greatly appreciated. Thank you!
