The bulb "Lighting EVER LED Bulb C37 Candle E14 4W Equivalent to a 35W Incandescent Bulb, Warm White", delivering a more yellow light of 340 lumens. I also bought "Vision-EL - Led Bulb 4W (40W equivalent) E14 - Shape opaque flame - White Day 6000 ° K" on the package, it is specified 295 lumens. This second model delivers a more powerful lighting. For both models, full power instant start. My choice will be the second model for my future purchases.
