What are standard sizes for fluorescent lights?
While there are multiple types of LED and fluorescent tube lights, the three most common are T12, T8 and T5. The terminology comes from “T” for “tubular” and the diameter of the bulb in eighths of an inch, so “T8” represents a tube of 8/8ths of an inch, or 1 inch.
What size do fluorescent tubes come in?
Fluorescent tubes have two dimensions; diameter and length. The type of tube is determined by its diameter, with T2 (7mm), T4 (12mm), T5 (15mm), T8 (25mm), T12 (38mm) all available in multiple lengths and wattages.
Are fluorescent bulbs a standard size?
Fluorescent circline tubes are typically 1 and 1/8 of an inch in diameter. Their outside diameter (which is measuring the circle from one end to the other) comes in four options – 6, 8, 12, and 16 inches.
How do you measure the length of a fluorescent light bulb?
For length it is imperative to measure your tube to the end of the tube including the pins. Sometimes it is easier to use a tape measure than a small ruler.
What is difference between T8 and T12 fluorescent bulbs?
The main difference between T8 and T12 tubes is the tube’s diameter. T12 tubes are 1.5″ in diameter while T8s are just one inch. All other things—socket sizes, lengths, distance between pins—are the same. T8 LED tubes won’t fall out if you try to install them in a T12 fixture—they’ll fit just fine.
Can you replace T12 fluorescent tubes with LED tubes?
T8 LED tubes won’t fall out if you try to install them in a T12 fixture—they’ll fit just fine. But here’s some even better news: If you have a T12 fixture, conversion to LED is going to be even easier than with a T8 fixture. This is because T12 fixtures have non-shunted tombstones, exactly what you need for LED tubes.
Which is better LED lights or fluorescent lights?
LEDs have an extremely long lifespan relative to every other lighting technology (including fluorescent lights). New LEDs can last 50,000 to 100,000 hours or more. The typical lifespan for a fluorescent bulb, by comparison, is 10-25% as long at best (roughly 10,000 hours).
