Natural light for home and public places

High CRI Ledtek COB LED strip for 12 Volts! 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 1000 lm/meter and the color of the light is a pleasant natural white 4000K (white light without blueness). This COB LED strip has 488 small LEDs/meter and there is a COB mass on the LEDs which makes it a uniform, dotless light.

This novelty COB LED strip is IP67 protected and waterproof protection has been done with a nice white silicone cover.

Silicone cover is UV protected, yellowing-protected and it has a protection for salty climate.

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 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. This 5 meter reel has 15 cm wires on one end. COB LED strip can be dimmed the same way as our SMD LED strips. IP67 COB LED strip surface is soft and antistatic. The width of this COB LED strip is 10 mm, cut points every 5 cm and operating voltage 12 Volts. Protection class is IP67, so it has a great protection from water. A good suitability for bathrooms and saunas. Cut sections have good copper points for soldering and connectors. The long coppers of this COB LED strip are better than the short ones in some normal LED strips. On the backside of the LED strip there is a strong double-sided tape and in addition silicone mounting clips are included. Silicone endpieces are included to help with sealing the cut points. Just add silicone and an endpiece so that you can keep the same protection class also on cut points.

Applications:

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

Dimmable COB LED strip

Ledtek COB LED strips are dimmable. For dimming LED strips you basically have two choices.

1. Dimming happens after LED-driver
2. 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. If you use connectors, choose 8 mm COB connectors. Notice! Normal SMD LED connectors are not suitable for COB LED strips!
Usually LED aluminum profiles are recommended for LED strip projects but with this strip it is not that necessary. This COB LED strip looks nice even without aluminum profile as well. White, squared silicone cover makes the strip look nice and it can be installed as such for example on terrace or sauna. This LED strip is IP67 waterproof and it can be installed in damp and wet spaces. You can use LED profiles with this COB LED strip. A good profile for example 1707 aluminum grey, 1707 white, 1708 black, 1616 aluminum grey, black or white, 2310 slim.
