What is a T5 high output bulb?
“HO” stands for high output. T5 HO lamps deliver more light than standard T5 lamps and are available in higher wattages. HO lamps have the same diameter and length as standard T5 lamps.
Are all T5 lamps high output?
T5 lamps are available for standard output and high output. The wattages for standard T5 lamps are 14, 21, 28, and 35 watts. The high-output T5 (T5 HO) lamps are available in 24, 39, 54, and 80 watts (49-watt T5 HO lamps are also available from GE Lighting).
How many lumens does a T5 have?
While the standard T5 and T5 HO are the same diameter and length, the 4-ft T5 is rated at 2,900 lumens, similar to the lumen per watt output of a T8 lamp. On the other hand, the 4-ft T5 HO lamp is rated as high as 5,000 lumens, offering twice the maintained light output of a T8 lamp.
What is the brightest T5 bulb?

Which fluorescent tubes are brightest?
T5s are fluorescent tubes that are 5/8 of an inch in diameter. These are the newest development in the fluorescent family. Although they are the smallest, they are the most energy efficient and brightest. In fact, some T5s last up to 90,000 hours.
How high should T5 grow lights be from seedlings?
The best height for a T5 grow light is about 6-8 in. above the plants, but you should increase that gap to 12 in. if your plants don’t like heat or they are in the seedling growth stage.
How high should my T5 be from my plants?
around 12 to 18 inches
When it comes to hanging your T5 grow lights, you’ll want to hang them around 12 to 18 inches above your plants. Unlike HIDs that you’d need to hang 18 to 20 inches above plants, and LEDs that need 20 to 24 inches of space above plants, T5s don’t have the same intensity as other lights.
