These high output (HO) fluorescent T5 tubes offer excellent efficiency and produce about twice the amount of light as the standard T5 bulb. Lights are available in 2 different color spectrums. The 3000k bulb provides increased output in the red spectrum which promotes flowering & budding in plants. The 6500k bulbs are full spectrum bulb which promotes overall plant growth.

PLANT GROW LIGHT GUIDE
Growing Area
The growing areas listed above assume the light bulbs are being used in a fixture
with a reflector similar in quality to the ones offered on this web site.
Primary - Use this area if the grow light will be the main or only source of light for the plants. This includes areas where minimal light comes from windows or standard house/office lights.

Secondary - Use this area if the grow light will be used in a greenhouse or other area that receives direct sunlight for part of the day to supplement the light from the sun.

How Long Should Grow Lights Run?
This depends on the type of plant. Foliage plants need about 14-16 hours of light per day. Flowering plants need 12-16 hours of light per day. You should give most plants at least 8 hours of total darkness daily. Try to have the lights on at the same time every day. Using an automatic timer for your lights is recommended to make it easier.
The Electrical Cost to Run a Grow Light System
To get the operating cost per hour for a light, take the lights combined wattage, and divide it by 1000 to get the kilowatts used. Then multiply that number by the amount your electric company charges per kilowatt hour. HID lights will use the number of watts it emits per hour, ie; 600w system will use 600 watts per hour (regardless of spectrum).
(light wattage output / 1000) x electricity cost per kilowatt hour = Operating cost per hour
operating cost per hour x hours used per month = Operating cost per month

Sun blaze fixture with T5 fluorescent bulbs

Rating:
We have two of the sun blaze fixtures and they keep a Persian lime plant happy and producing fruit in an office space.

Great T5 bulbs at a great price!

Rating:
I purchased T5 lights and the bulbs that came with them burnt out out pretty quick. This is the second order I have placed with ACF for bulbs (because I added more T5 lights where the bulbs burnt out) and they get it right each time. Bulbs are well-packaged and arrive in record time. The bulbs are high quality and last. When I have to buy bulbs again, which may not be for awhile now because these bulbs are so awesome, I will certainly go with ACF!
