FAQ:
Q: How many Watts Does a T8 light bulb use?
A: For fluorescent bulbs, the number after F tells you how many Watts; a F17T8 is a 17 Watt fluorescent T8 lamp. A common T8 bulb is the F32T8 which uses 32 Watts of power. The wattage for LED tube lights varies depending on light output as well.
Q: Are T8 bulbs good for growing plants?
A: Interpet Aquatic T8 bulbs are designed for growing plants without the same levels of mercury per tube, resulting in less hazardous light emissions. 36-watt bulbs produce enough natural light to promote plant growth at around 6,000 Kelvins; noticeably lower than other varieties.
Q: Will a T8 bulb work on a T12 ballast?
A: Yes, only T8 bulbs will work properly with this ballast. Using T12 bulbs can cause burnout for the bulbs and/or the ballast. As someone else stated the UNIV refers to the input voltage, not the type of bulbs you can use.
Q: Can a T8 led replace a T12?
A: T8 lamps can serve as a replacement for T12 if they use a two-pin G 13 base, for example. In this case, you can use the same device by checking the requirements in milliamperes for ballast. Otherwise, you need to buy a replacement T12 for magnetic ballast. Or install an electronic ballast to use T8 and T5 bulbs.
