Going by Rapidled's calculator for plants tanks you will need tanks footprint divided by 25 i.e 48x18/25= 34.56 Led. ( Their calculation is based on Cree Led ). For Led's like edison, exiled I guess you will require twice that number.

does the formula assume any height? 1feet 3feet etc
Nothing, but I assume this should hold good till 18".

I have a tank of size 24inch(L)x12inch(B)x18inch(H). I have put two LED bulbs of each 9W. Is it sufficient for the plants?

Depends on the type of Led bulb. Ideally it should be able to support lowlight plants.

I am using Wipro 9W LED which has 900 LUMEN. Using TWO. So what factors I need to check to verify whether they are sufficient?

I have Amazon sword.

I have a question. Taking consideration of my tank size and LED preference, How much WATT should I use for a healthy plant growth?

Watt per gallon doesn't hold good for LEDs, going by rapidled's guide you will require 12x24/28~11 x 3W led, but these calculation are for efficient Cree Led's, for less efficient chip you will have to use more. In case you are planning for low light plants like Amazon swords, I guess 2 of the bulbs that you are using right now will be more than sufficient.

Hi all,
Is anybody using led floodlights in their tanks?
Like the 7 watt led flood lights by phillips in 6500 k?
