Note the following as described: this bulb is not dimmable! To see the product and not the product information. 2900 Kelvin I have hinnemen in confidence, may be but I feel not as warm white! There is too much of green in the light. The light looks more grayish. Since no heat is on ...... Still unbeatable 4.5W use power that's the right way. One should consider the application well in advance! And even if this would lamps Dimmable have to anyway so keep account the need to acquire new generation of dimmers can be dimmed from 2W!
