I wanted to know if the bulb comes in a higher wattage, 15W is low for what I needed. I have been looking for a full spectrum higher wattage bulb that would fit into a standard socket.

Regina, We have some higher wattage Full Spectrum (a.k.a. Joyous Light) bulbs however they tend to be larger than a standard light bulb but now I'm re-reading your message and you say 'that would fit a standard socket'. So can I ask if the size of the bulb itself is an issue or is it just the socket? (All our Full Spectrum lights have standard sockets. Thanks - Michael
