Thank you for your review. The bulbs can be replaced with brighter, higher wattage LED bulbs. Each socket is rated for 60-watts maximum. One suggestion for bright light output would be a 100-watt equivalent LED bulb like the Ecosmart light bulbs (model #A7A19A100WUL03). The 100-watt equivalent offers almost twice the light output. In general, we suggest using a ceiling fan light as a supplemental light source used in conjunction with other lighting like lamps or recessed cans as opposed to the sole source of light for any room. Edit: the Altura fan is compatible with any of the Hampton Bay universal ceiling fan light kits. This light kit was designed to complement the Altura fans, but the Altura is compatible with other light kits as well.
