LED Strips CCT

In LED strips with adjustable colour temperature, warm white and cool white LEDs are mixed on one strip and can be controlled individually. This allows flexible adjustment of white light types from warm incandescent light to cool daylight.

These types of LED strips are also known as Tunable White, Variwhite, Dualwhite or BiColor. We mainly use the term CCT LED strips - derived from the English "Corelated Color Temperature".

Novelty: COB LED strips with adjustable color temperature (CCT): 24 volts - CRI>90

LED type: COB warm white & cool white mixed 2,700 - 6,000 Kelvin Brightness: max. 850 + 950 lm/m* Colour rendering: High CRI>90 Voltage: 24V Power: 19,2 Watt/m (real approx. 10W/m) Width: 12mm Price for 1 roll = 5 meters - Buy by the meter - Innovative CCT LED strip where no individual LEDs are visible! A continuously bright, uniform light band is produced. This has advantages for various applications: Homogeneous line light, even in very flat aluminium profiles Continuous, narrow accent or orientation light Absolutely uniform indirect lighting at very short distances In this COB LED strip, warm white and cool white LEDs are mixed. This allows the colour temperature to be adjusted flexibly. From warm light similar to incandescent lamps to neutral tones to cool daylight. *Many LED drivers, such as our LK55 series, keep the brightness of CCT LED strips constant, regardless of the selected color temperature. This means that at a medium color temperature like 4,000 Kelvin, warm white and cool white LEDs are not controlled with 100% each (which would mean 19.2W/m power consumption), but only with approx. 50% each. Thus, the LED strips are always equally bright, no matter which color temperature is set and also the power consumption remains constant at only about 10W/m. Available versions 5m roll IP20 without water protection, incl. 10cm connection cable The LED tape is also available by the meter in IP20 in lengths of 1 - 30m. All versions have a 3M adhesive tape on the back for mounting and can be divided every 4.2cm. Notes on accessories: To operate 5m (1 roll) of LED strips, a 24V power supply with min. 75 Watt is required. 5m x 14W/m = 70 Watt.https://shop.led-studien.de/de/zubehor/netzteile/24v-netzteile For brightness controll of 5m a driver with min. 3,2 Ampere is needed. 75W / 24V = 3,2 Ampere. https://shop.led-studien.de/de/controller/dimmer-1-2-kanal It is best to use the LED strip with a suitable aluminum profile or other solution for cooling. Due to the high power, the LEDs would lose brightness and lifetime very quickly without an aluminum profile. We recommend aluminum profiles with cover to protect the LEDs like our PL1.

Extra warm white - CRI>95 - 240 LEDs/m - 700 + 900lm/m

LED type: 2216 - 120ww+120nw LED/m extra warm white & neutral white mixed Color temperature: 2.200 - 4.000K Brightness: max. 700 + 900 lm/m* Color rendering: High CRI>95 Voltage: 24V Power: 19,2 Watt/m (real approx. 10W/m) Width: 10mm Price for 1 roll = 5 meters - Buy by the meter - This LED ribbon has a special color mixture that uses an extra warm white LED. While typical CCT LED strips only start at 2,700 or 3,000 Kelvin, extra warm LEDs with only 2,200 Kelvin are installed here. This warm white corresponds in color tone (not in brightness!) to a dimmed incandescent light and is therefore intended for particularly comfortable lighting moods. Alternately, neutral white LEDs with 4,000 Kelvin are installed next to each extra warm white LED. This means that any color temperature can be set between a deep warm white 2,200K, through the typical 2,700 and 3,000K to the neutral, elegant 4,000K. In addition, the LED strip offers exceptionally high color rendering CRI>95 (R9 also >90). This guarantees absolutely natural colors across the entire light spectrum. At 4,000K, the LED strip offers a brightness of 900 lumens/m. At the extra warm white 2,200K, it is then still about 700 lumens/m. This makes the LED strip ideal, for example, when it comes to indirect lighting of small to medium-sized rooms. *Many LED drivers, such as our LK55 series, keep the brightness of CCT LED strips constant, regardless of the selected color temperature.

3D light simulation - What brightness is achieved?

Professional 3D light simulation of your room Detailed result with brightness values and light distribution in the room E.g. for indirect lighting, solutions with LED profiles or lighting with LED spots You will receive results by e-mail within 5 working days With most lighting solutions in private or commercial rooms, a certain brightness is to be achieved. Especially when it comes to a room's main lighting. A simple light simulation can answer the following questions: What brightness can I expect if I use components xy? How uniform will the light distribution be in the room? Do I have to use brighter LED strips / LED spots to achieve my goal? The result of the light simulation shows the light distribution in the room in a clear graphic. You can immediately see which brightnesses are to be expected and where something should be adjusted if necessary. In order for the light simulation to provide the most precise results, the following information is required: Floor plan of the room with all dimensions (clearly legible!) Ceiling height of the room (ridge and knee height if applicable, if there are sloping roofs) Wall and ceiling colours or wall and ceiling design of the room, so that we can estimate the reflective properties of these surfaces. Detailed drawings of any coving, ceiling suspensions or stucco mouldings that have already been planned, including dimensions. Photos, if necessary, so that we can better assess the project. After ordering the light simulation, you will receive a personal e-mail from us to which you can send all the necessary data. You will receive the results of the light simulation by e-mail after 5 working days at the latest.

LED spectral measurement

You receive a spectral measurement and evaluation of an LED strip or an LED module. One LED each is measured at 3 different points from a roll purchased in the shop. The measurement protocol as PDF contains: 3 x spectrum from 340-750nm3 x colour temperature3 x colour location in the CIE1931 diagram3 x colour rendering index (CRI) as well as the values of all test colours. This is particularly useful for projects where absolute accuracy in light colour is important. This gives you a very precise, professional indication of the colour parameters of the LEDs. For later re-orders, for example, you can compare how well the batches match.

Control

Special LED controllers, such as our LK55 or the ZigBee variant LK115-U, are needed to adjust the colour temperature. The LK55 offers various radio control options, such as handheld remote controls and wall-mounted models. The LK115-U is designed for control via app (e.g. PHILIPS HUE or ALEXA). Controllers for other smarthome systems such as KNX, DALI, EnOcean, Zigbee etc. are also available. As well as variants for DMX.

Of course, these controllers allow flexible dimming from 0 - 100 in addition to setting the colour temperature.

Notes on our LED strips:

All our LED strips are dimmable! Choose an appropriate driver for this.

All our LED strips are equipped with a 3M adhesive tape on the underside for easy installation.

We can spectrally measure all LED components for you in advance if required.

The product group "LED strips" is also referred to by the synonyms "Flexband", "LED Band", "LED Strip" or "LED Stripe". All terms mean the same product.

What is the difference between the individual LED strips?

Depending on the application, you should select the appropriate LED tape from our range. Important criteria are:

Brightness in lumens per meter - short lm/m

For accent and effect applications, LED strips with a brightness <1,000 lm/m are absolutely sufficient. You can also work with these strips for the main lighting of small rooms (around 15m²). In larger rooms, however, LED strips with >1,000 lm/m should be used if main room lighting is to be realised. For special applications, e.g. where a rather short LED strip is to illuminate an entire room or where very high luminous intensities are required (example: some workplaces), even higher values are recommended.

LED-Type - 2835, 2016, 5630, ...

This specification describes the design of the individual LEDs on the LED strip. For example, an LED type 2835 is 2.8mm wide and 3.5mm long. The only important thing for you is that you should not mix LED strips with different LED types in one room. Slight colour deviations can occur here, even if both strips are described with colour temperature 3,000K, for example. If possible, stay with one LED type.

Colour rendering CRI

The colour rendering index (CRI) indicates how natural the light of the LED strip is, i.e. how true-to-life the colours illuminated by the LED light are reproduced. Today, qualitative applications should always work with a CRI>90. This is of course even more important for main room lighting than for accent applications. Since a high CRI always slightly reduces the efficiency of the LEDs, super-bright LED strips are usually only available with CRI>80.

LED density in LED per metre - in short LED/m

This specification is self-explanatory. A very high LED density is important if you want to use the LED strip behind a milky opal cover, for example, but do not want to see individual LEDs. This is often desired for direct lighting, e.g. when line luminaires are built with the LED strips. Only with a high LED density (120 LED/m or more) can a continuous band of light be created in which individual LEDs are no longer perceptible. If the distance to the milky-opal cover is very short, even an LED strip with considerably more, e.g. 300 LED/m or directly COB LED strips should be used.

What is the advantage of "COB"?

COB LED strips have no visible individual LEDs. The chips are covered with a phospore layer over the entire 5m roll, creating a completely uniformly illuminated strip of light. This is particularly advantageous for all applications in visible areas or where the LEDs are a very short distance from the wall or ceiling.

LED strips according to customer specifications

You need special LED strips or LED panels according to individual specifications? E.g. with a special LED mix or in certain brightness levels, colour rendering qualities, as BiColor, RGB + WW + CW or with a certain number of LEDs?

LED-Studien can have these individual LED strips or LED panels manufactured for you. Just talk to us.
