Do these exist? I am currently using the clip on type. I am now feeling like putting something a bit stronger than that on my tank for the plants. Any suggestions or ideas?:help:
my best guess the ballast can only use what ever the watt is now. so say its 10watt and you were able to find a 20watt bulb. if you put it in it still only would be 10 watts. maybe if you added another one of them and doubled your light.
