I think so cause I think mine is about 20w also and I think our tank sizes are the same

 

A 20W bulb over a 20G tank will give you exactly 1wpg. I don't know about the effectiveness of bulbs other than fluorescent for planted tanks so I can't help you with that. But a 20W fluorescent bulb for a 20G tank would be OK I suppose, if the plants are low-light and slow-growing. Though on Plant Geek I have read that the smaller the tank, the more wpg's it actually needs.

Oh, and if the bulb you're getting is incandescent, be careful not to overheat your tank with it.

 

it could end up being a 15watt bulb that I get with my new tank but the 15watt I hav with my current tank the plants hav grown well and hav been fine !
