20 Watt White LED Tape

3528 SMD, 120 LEDs Per Metre
Commercial Grade

Availability: In Stock for next day delivery

The 20w White LED Tape is a thin and flexible LED light strip at only 10mm wide and 3mm in depth. The 20w LED tape has 120 x 3528 double power branded LEDs and has up to 1440 lumens per metre with 50,000 hours continuous use life.

The LED strip gives a smooth effect once shined onto a surface or alternatively it can be fitted into our aluminium extrusions to diffuse the LEDs if looked directly at the source. The 20w LED tape is 4 x as bright as our standard 5w per metre LED tape that is ideal for plinths and covings as feature lighting. Therefore the 20w LED tape is ideal to be used as general or ‘working light’. The LED tape can be used to replace fluorescent tubes, or used in a variety of applications such as under kitchen cabinet lighting, signage, bars, restaurants and more.  The cut points for the LED tape are every 50mm, and Instyle LED offer a cutting and soldering service so we can make up the specific lengths you require for your project.

This LED tape is also available in an IP67 rating, meaning the LED tape can be used externally or in bathrooms or wet areas. You can also have the IP67 LED tape just for ease of cleaning the product.

Instyle LED stocks the following kelvin rating whites as standard: 2700k / 3000k / 4000k / 5500k / 6000k / 6500k and we may also have other varieties in stock or we can manufacture specific requirements on request. InStyle LED supplies commercial grade LED Tape using premium components, built to last with consistent colour batching.  At InStyle we have many various ways to dim the LED tape from Wireless to DMX to Triac to 0-10v, and more.

20 Watt white LED Tape Datasheet PDF


When looking to use white LED lighting you may think it would be a very simple choice to choose as there is only one option…white?
Wrong; there are actually different various shades of white to choose from.

The 3 main shade descriptions of whites are:

  • Warm White (also known as soft white) – being described as warm white does not mean that it is warm to touch, the warm is actually describing the shade of white the LED lights up. Warm white tends to be a slightly yellow/brown in colour just like your standard halogen light bulbs. Warm white tends to be used to give a warm, homely feel. The technical specification of warm white is anything from 2700k – 3200k (lower being warmer)
  • Pure White (also known as daylight white, commercial white, bright white) – this is the closest resemblance to daylight white, it tends not to have any yellow (warm) or blue (cool) tint to it. This is used in commercial applications and also to highlight areas; it is generally brighter than warm white. On the kelvin scale pure white would be anything from 4500k to 6000k (lower being warmer)
  • Cool White – this white is used the least out of the 3 as it is generally too ‘cool’ (blue tint) for commercial and general use. However it is the brightest white and can be used to highlight areas. It still looks very white and the blue tint is extremely faint. This is great to create a cool, crisp feel. On the kelvin scale this would be 6500k+

For more information, see our support page explaining all your white LED tape options.

To work out what transformer you require this is quite simple. You take the amount of LED tape you have in metres and x this by the wattage of the LED tape you have, again per metre.

For example 9-and-a-half metres of 19.2w LED tape: 9.5 x 19.2w = 182.4w Therefore you would require a 200w transformer.

For more information, see our support page on LED power supplies and their output.

InStyle LED manufacture and supply commercial-grade LED strip lights – which means our products are high quality and built to last, using only premium components and branded LEDs:

  • Brighter LEDs
  • Vibrant and consistent colours
  • Accurate life expectancy
  • Sturdy PCBs
  • Excellent resistor management

Find out more on our ‘commercial-grade LED’ support page.

The LED tape can be dimmed in various ways.

1 option is with our dimmable transformers: these are available in 12v/24v and in 30w and 100w. These can then be dimmed off a standard Triac wall dimmer (standard in households).

We also have Triac dimmable receivers; these go in-between the transformer and the LED strip. These work with both 12v and 24v version and are ideal for larger projects that use larger transformers such as the 320w.

Another option is with our 0-10v receivers, these can be used for both the 12V and 24v version. They go in-between the transformer and the LED tape and can be linked to such systems as Lutron.

We also have the option to dim via DMX. We have DMX receivers available to work with DMX desks and systems to allow you to fully dim as required. Again these go in-between the Transformers and LED tape and can be linked together to dim all the receivers at once.

For more information, see our support page comparing options for LED dimming.

For this type of LED tape you will require just a transformer to get this working. You connect the 2 core starter lead coming out of one end. This is then wired to the transformer, red wire goes to + and the black wire is wired to -. The 2 core cable can be extended as required for you to mount the transformer as far away as required.

For more information, choose one of these links for support and advice on how to install either simple or larger LED tape projects.

Deciding on which wattage you require is all down to what kind of application you are fitting the LED tape in.

The 5w and 10w is ideal to be used as feature lighting. Lighting to highlight areas, as a secondary lighting. Ideal for covings, drop down ceilings signage etc. to give a smooth halo effect. The 10w would be preferred to the 5w for these applications if there is a high amount of ambient lighting.

The 15w and 20w is ideal to be used as general lighting or as feature lighting for areas larger than covings etc. For example washing down front bars / back bars / under kitchen cabinet lighting as ‘working light’.

For more information, see our support page discussing how bright your LED tape needs to be.

IP67 Heat-shrink type is required in areas where you will need resistance to water. For example bathrooms, kitchens and exterior. The heatshrink version is waterproof but it cannot be submersed, for example in a pond. The IP67 Heat-shrink is a protective coating over the LED tape, this makes it easy to wipe to clean etc.

For more information, see our support page describing the waterproof LED strip light options we offer.

All the LED strips are cuttable. Each can be cut at various points, either 50mm,100mm,150mm or 200mm depending on whitch wattage version you have. We can either cut the lengths to your specific lengths as required or you can do this yourself. Once cut to length to join this to a transformer or another piece you will need to be capable of soldering, or if not we also supply 2 types of clips. One type is a starter lead clip, which is s clip that joins onto the off cut and has a cable coming out of it. The other clip is a ‘tape to tape clip’, this clip joins 2 pieces together.

For more information, see these links offering advice and support on cutting and soldering your LED tape, or using clip-on connectors to extend your tape’s length.

Very bright and nice colour

The warm white was a nice warm white 2700k. Usually the warm white using LED's can create various red or green 'tints' but the type ordered from InStyle was a true warm white

by Stephen Shore on 20-watt white LED strip lights (120 diodes p.m.) by InStyle

Quality customer service as always. Ordered some 20w LED Tape 6 months ago and needed to order some more exactly the same colour as some was damaged by a builder. InStyle managed to find the exact match saving me having to change all of the LED Tape

Quality product from InStyle

Another quality product from InStyle LED. We were looking for a bright product that the 15w that we usually as the area we were installing has a lot of ambient lighting. This product worked perfectly. The LED Tape is the brightest we have found on the market,

Great product. Saturday delivery was extortionate though
