These bulbs are more than adequate as 'main lights', of the few remaining traditional white cheap bulbs in the house I doubt any have been turned on so far this year - we only use the Hue bulbs now. Of course one solitary bulb 10' up in a 30' x 15' living room may not suffice, but if that's all you have swap the fitting for something that can take several bulbs and use Hue bulbs, it will make such a difference to the room.
