Natural light for home and public places

High CRI Ledtek COB CCT LED strip 3000-6000K. The quality of light is excellent CRI90+ which makes it a pleasant light. This LED strip is suitable for projects that require stronger lighting. Light output is 1360-1700 lm/meter and the color of the light (CCT) is adjustable between 3000-6000K. You get warm white 3000K light, 4000K natural white and 6000K cool white light from one LED strip. With CCT controller/dimmer you can adjust the white light color steplessly. This COB LED strip has 608 small LEDs/meter and they are covered with COB mass which makes it a uniform, dotless light.

Quality of light matters

Color Rendering Index (CRI) tells you how well different colors are reflected by the light source in comparison to sunlight. Index measured in range 0–100. Perfect 100 tells that the colors under the light source look the same as they would be under natural sunlight.
High CRI value is important especially in photography, stores, markets, restaurants and other places where colors are required to look as natural and rich as possible. Is there any other more important place than home where a lot of time is spent? It is comfortable to spend time in a high-quality-lit spaces.

Measuring CRI value requires a special type of light tester. We have such a device. CRI of this LED strip is over 90 which means that the quality of light is excellent. You can check accurate test results below.

CRI100 = perfect result, CRI over 90 = excellent quality of light, CRI over 80 = good quality of light

Ledtek COB CCT LED strip

With COB CCT LED strip you can create a premium class uniform dotless light without aluminum profile. Just as with our high density SMD LED strips, the same kind of uniform dotless light can be achieved with COB LED strips. In comparison to typical LED strips we have 2 meters of installation cable on both ends of a 5-meter reel. This is a significant matter since it does make installation process much easier when you don’t have to start making a connection to 20 cm wires that you have in basic strips. With this COB CCT LED strip you get to hide the connection part like it’s supposed to be. COB LED strip can be dimmed the same way as our traditional LED strips. The surface of COB CCT LED strip is soft and antistatic. The width of this COB CCT LED strip is 10 mm, cut points every 2.6 cm and operating voltage 24 Volts. Protection class is IP20, so it is intended for indoor use. You can install it in damp places when you protect the LED strip with an LED aluminum profile + cover + endpieces. Then the possible strain from dampness will remain outside the profile and cover. At cut points there are long copper points for soldering and connectors. The long copper points of this COB CCT LED strip are better than those short ones in some traditional LED strips. COB CCT LED strip wiring is 3-pole. Please pay attention to that when doing the wiring.

Applications:

• LED strip for general lighting
• LED strip for kitchen interspace
• On cabinets for general lighting
• For stairs behind hand rail
• For shelf and level lighting
• For lighting profiles
• Curtain cases
• Indirect lighting

Dimmable COB CCT LED strip

Ledtek COB CCT LED strips are dimmable. For dimming the LED strip you will need a CCT controller/dimmer that is equipped with handling the LED strip CCT adjustment.

  1. Dimming happens after LED-driver
  2. Dimming is done before LED driver (for normal LED strips it can be done as well, but not for CCT)

When dimming is done after LED-driver, it happens with a so-called PWM-dimming (Pulse Width Modulation), where signal is being cut with fast sequencing. If PWM is done with a low Hz, final result is a flickering dimming. Flickering can cause headaches among other things. Low 200Hz PWM is something that you can find for example in cheap dimmers. We can provide you with high quality dimmers where PWM is a non-flickering 750Hz.

The other dimming option is to do it with a dimmable LED-driver. For this you will need a compatible light dimmer (LED dimmer) and Triac or DALI dimmable LED driver. In other words, the dimming signal comes from the front-end of the power source. Good dimmers are available such as those from ABB and Schneider. This cannot be done with CCT LED strips, however.

What do you need for installation?

In addition to LED strip you will need an LED driver and a CCT dimmer. To make things easier with installation, there are 2 meters of cable on both ends of the reel. In typical LED strips there is only a 20 cm cable on one end of the reel. You can cut appropriate lengths from the strip and you have long connection cables at the ready. You don’t necessarily need COB CCT connectors or soldering. If you’d like some connectors, choose 10 mm COB CCT connectors. Notice! Connectors meant for normal SMD LED strips cannot be used with COB CCT LED strips!
Usually it is recommended to use aluminum profiles for LED strip installations. With COB CCT LED strip this is not absolutely necessary due to the uniformity of light, but considering heat dissipation aluminum profiles are recommended. This LED strip is IP20, for indoors. You can install it in damp places when you protect the LED strip with an LED aluminum profile + cover + endpieces. A great profile for example 1707 aluminum grey, 1707 white, 1708 black, 1616 aluminum grey/black/white, 2310 slim.
