The light is pleasant warm white. While it is not as yellow as the Noname bulbs, but far from my cold-white-cheap LED spots. The light is even brighter than the no-name 50W lamps.
Even if the price is felt quite high, I give thanks to energy savings (90%), the long service life (40,000 hours, according to packaging) and good performance, a strong buy recommendation!
Although it is not mentioned in the product description, Philips granted (according to their website) 3-year warranty for this product.
The hum I have mentioned only a lamp of 6 lamps. It is not on the bulbs, but only on the combination of lamp bulbs.
