t5ho lamps


Do 22" t5ho lamps come in higher wattage than 24 watts? I have a dual fixture running a 5000 and 6500k right now. I have a 37 high. I think I'm right at the low end of medium light.. I was just wondering if I should go higher. Like maybe a 10000k lamp?
My plants:
Anubias
Amazon sword
Christmas moss(in mesh now for about 10 days)
Argentine sword
hornwort
water sprite
S. repens

I'm still pretty new at this myself, but I believe with T5HO the wattage is determined by length. So 22" will always be 24 watts.
10000k refers to the 'color temperature' of the lamp. It will be brighter with a slightly bluish tint.
(see here http://en.wikipedia.org/wiki/Color_temperature)
While it can make things look brighter, some report that 10000k lead to algae growth.

Again I'm still learning myself, others will have advice too.

Thanks, I was just wondering if I should go to a higher k for my plants that I have.

5K to 10K is a good range. Many people find ~6.5K to be a good compromise. The temperature is the measure of how the light appears to the human eye. The plants use specific light wavelengths for certain biological functions. How much of specific wavelengths a given light bulb produces is commonly represented by a "spectrum" chart.

I don't think you need to for your plants. For aesthetics maybe.
Here's a pretty good thread.
