My previous IKEA lightbulb didn't turn on, so I went out to get a new one and turns out this is fairly cheap however note that it is 400 Lumens NOT 600 Lumens so it's not as bright. I personally don't have an issue with that seeing as it sits as a desk lamp. Beware though, this is the exact lightbulb that didn't work for me, i'm just buying it to give it another chance since it's an LED.
Here's the overall information though:
The light from this LED bulb feels as strong as the light from a traditional 35W incandescent bulb.
Not dimmable.
LED life time approx. 15.000 hours.
Light Colour: warm white (2700 Kelvin).
Lights up directly when switched on.
Use an opal light bulb if you have an ordinary lamp shade or lamp and want an even, diffused distribution of light.
The light bulb can be used in temperatures from -20°C till +40°C.
The led wattage is not 35W, maybe edit to remove it from the title as I read 35W and 400Lm and thought it's 1917 :D
