T5?

[ChoclateBetta]

If I can use a T5 light bulb in my ten gallon how many watts would I need for high light plants?

It depends on the bulb. There are two different kinds of T5s.

One, T5NO (or just plain T5) are much MUCH weaker in output than T5HO (T5-High Output).

For 10 gallons, and high-light plants, I'd aim for 3 watts per gallon of T5NO (T5). With T5HO though, you'd be fine with probably around 1.5-2 watts per gallon.

Your FIRST priority when choosing lights, however, is the Kelvin temperature.
Make sure they are between 5500 - 7600k. This range is best for plants.

i would throw out the watts per gallon rule
are you planning on having the light sit right on top of the tank? if that is the case t5ho lights will be too much light, but you could use 1 t5ho raised 4 inches above the surface of the water to get high light assuming you are using a 10g

this chart will help you:

I will be putting the light on the tank.

Have you considered LED lights? I use FugeRay: Ultra Slim LED. You just need to buy the one that fits the size of your tank. I've been using one on my newest 5 gallon planted and after seeing my plants tank off with it will be buying more for my other tanks. They are priced reasonable, will save you on electric bills, 7000k, and you don't have to replace the bulb every year. A con on it is you have to order them. Amazon is the best price I've found. A pro on T5 fixture/bulbs is you should be able to find easily where you live in a pet store.

Do plants grow well to LEDs?

[starrlamia]

if you have the proper LEDs then yes plants will grow with them

What would proper bulb be?

You should check out FugeRay if you are shopping for an LED. They are designed for planted tanks but don't cost an arm and a leg. Plus they come in sizes from 10" up to 48". LEDs aren't listed like florescent light. Basically you are looking for ones designed for plant growth. An LED with Kelvin listed on the box is one designed for planted tanks. I know Marineland makes them too and some specialty shops but they are pricey. The Fugeray I actually seen suggested by another forum user.I am happy I tried them

Can I have links to amazon for good lights that are high light and can be placed on the tank?
