Natural light for home and public places
High CRI Ledtek COB LED strip for example for sauna and terrace. The quality of light is excellent CRI90+ which makes it a pleasant light. This LED strip is suitable for spaces that require mood lighting, and the color of the light is a pleasant warm white 3000K.
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.
Ledtek COB LED strip
With COB LED strip you can achieve 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 normal LED strips we have 2 meters of installation cable on both ends of the reel. This helps considerably with installation when you don’t have to make an additional connection with traditional 20 cm long wires. With this COB LED strip you can hide the coupling like it should be done. You can dim COB LED strip the same way as our SMD LED strips. The surface of the LED strip is soft and anti-static. The width of the strip is 8 mm, cutable every 5 cm and operating voltage 24 Volts. Protection class on this waterproof COB LED strip is IP65 and it means good water protection. At cut points there are long copper points for soldering and connectors. The long copper points of this COB LED strip are better than the short ones in some normal LED strips.

• For spaces where waterproof LED strip is required
Is this LED strip dimmable?
Of course! Ledtek COB LED strips are dimmable. For dimming LED strips you basically have two choices.
- Dimming happens after LED-driver
- Dimming happens before LED-driver
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.
What do you need for installation?
In addition to LED strip you will need an LED driver and optionally a 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. COB connectors or soldering not necessarily required. If needed, choose 8 mm COB connectors.
Usually it is recommended to use aluminum profiles for LED strip installations. With COB LED strip it is not necessary. This LED strip is IP65 waterproof and you can install it in sauna without a LED profile. An LED profile is often used in installations since it makes installing easier. Profiles are mounted on the underside of sauna benches, then LED strip in the profile and plastic cover on top. A great profile for example 1707 aluminum grey, 1707 white, 1708 black, 1616 aluminum grey/black/white, 2310 slim. On the backside of the LED strip there is a good double-sided tape but in sauna it might not hold for long. If you want to avoid using LED aluminum profiles, another good option is a plastic corner profile and attaching LED strip on it with gluing compound.
