Kanlux LED Tube G13 T8 600mm 9W 1350lm Non-Dimmable - Cool White 4000K

This is a 600mm T8 LED tube, the size often sold as 2ft, in milky glass with a G13 cap at each end. It draws 9W and gives 1350 lumens, which is 150 lumens per watt. That is the figure to compare between tubes, because it tells you how much light you get for the electricity you pay for. Its 4000K cool white sits between the warm white of a typical household lamp and the bluer light of a daylight tube. Colour rendering is Ra 80 on a scale to 100, a common level for general lighting.

The maker does not name a place of application, so we would start with your fitting rather than a room. It needs lampholders for a 600mm T8 tube with G13 caps, each with two pins 13mm apart, and a 220-240V AC supply at 50Hz, which covers UK mains. Power comes in at one end only. A fitting wired for a fluorescent tube is not necessarily wired that way, so check yours before you buy and ask a qualified electrician if you are unsure. It is not dimmable, so it belongs on a plain on/off switch.

The SMD LEDs sit inside a milky glass body 28mm across, finished with white end caps. Milky glass scatters the light passing through it, softening the bright points of LEDs into a more even glow. The tube's 220-degree beam is wider than a half-circle, so as well as lighting the space it faces, some light travels back towards the surface behind it. Rated life is 30000 hours, a little over ten years at eight hours a day. Across a run of fittings, keep to one colour temperature, because tubes of different temperatures side by side show as visibly different whites.

Range Datasheet

Will this fit my existing fluorescent fitting?

Physically, it is a 600mm T8 tube with G13 caps, so it suits lampholders spaced for that length. The wiring matters just as much. It takes power from one end only, so the fitting must deliver the supply to that end, and one wired for a fluorescent tube is not necessarily set up that way. If you are unsure, ask a qualified electrician to check before you buy.

How bright is this tube?

It gives 1350 lumens from 9W. Watts measure the power a lamp draws and lumens measure the light that comes out. To weigh it against the tube you have now, look at lumen figures rather than wattages.

What does 4000K cool white look like?

It is a crisp, clean white. It is whiter than the warm white of a typical household lamp at 2700K to 3000K, without the blue tint of a daylight tube at around 6500K. If other tubes share the space, choose 4000K for those too so the whites match.

Can I use it with a dimmer switch?

No. It is not dimmable, so it should go on a circuit controlled by an ordinary on/off switch rather than a dimmer.

Is the tube glass or plastic?

Glass. The body is milky glass, which also serves as the diffuser, spreading the light from the LEDs inside more evenly. Glass holds its shape, but it will break if dropped, so keep a steady grip while you fit it.

How long will this LED tube last?

It has a rated life of 30000 hours. At eight hours a day that is a little over ten years, and at twelve hours a day nearly seven. It is a rating, so treat it as a guide rather than a promise for every tube.
