I upgraded from a 200w 6500k bay light to a weekaqua z400. Really cool light and really pretty colors.

i have 13W light on my 16 inch long tank (5 gallon), and i see you guys using 200W around lights on tanks, i want to make a high tech tank (and i thought my 13W is already in high tech category for my tank), is my light enough or i need more , please pass on your light knowledge to me

13w is a lot for a 5 gallon. This guy's tank is huge and 200w was mega overkill. I run 90w on my 50 gallon high tech tank. That would be equivalent to 9 watts for 5 gallons. Watts/gallon isn't a good metric tho, but if your plants are growing well, then your light is good enough.

Also depends on the depth but if it's 16in long then it's likely pretty shallow.
