Yes. Try to get UV protection PL lights. It cost about RM36-40 each. If your tank is 4ft. Then you need to get 4 PL tubes...it is around RM160.

For FL light tube, you need to change it every 3 months. coz it will get darker n darker.... i watch the Azoo planted tank VCD. They recommended that.

I am using a normal FL light tube which is 6900K. 3 of them for my 4ft tank. I know it is not enough. But the plants growing very well.
