Lights for RTGs

[classic-chassis]

My tank has a black baground, and dark pebbles on the bottom.
There is a splash of green with planted driftwood. I want it to be brighter than it is now. I know White lights are the way to go with RTGs so,
1: does Kelven make lights brighter?
2: Would lights with 1400 Kelven be harmful to my RTG.
3: Or is it just plane old watts that make light bright?
I read in "set ups" soem people use coral lights.
My hood has 2 tubes in it.
Any ideas on how I can make my tank brighter

Kelvin is the color temperature, lower number indicates a cooler (bluer) light cast, higher Kelvin numbers indicate a warmer (orange) light cast. Mid range numbers give a red/pink color cast. Wattage can give you more intense light depending on the color temperature. High Output lights produce a very bright light, but nothing like Halide. I'm not sure if 1400 Kelvin will be harmful to your RTG... I really don't know.
From my understanding you don't want a super bright tank for Arowanas, they don't particularly like bright lights. Try and find the balance of wattage and Kelvin, this will help to bring out the colors in your fish without giving them a sunburn.

This is a great question and I hope other more experienced fish keepers add their knowledge to your post.

Hope this helps,

Richard

6700k is yellow
10000k is white
14000k is blue and the high K is more blue

I would say 10000k is good but, I prefer a mix of 6700 K and colormax bulbs( so try a tube of each in your hood) Kelvin is a measurment of color, wattage is intensity if you use to powerful of lights it will darken the back of your aro.

I'm a photographer so in camera terms it's just the opposite, lower is cooler, higher is warmer, sorry about the confusion.
