I use neutral/white LED bulbs (from 3500K to 5000K) for all my lights and lamps. These lamps, with a temperature of 4000 K, should emit white light. Instead, the light they produced had a certain blue cast. I returned them.
Pros
★ SPECIFICATIONS - Using high efficiency and large LED chips in filament, full brightness 300 lumens, AC 110-130V, with overload, short circuit and overheat protection
