What is COB LED Strip?
The new Unitop flexible COB LED Strips are strikingly consistent in color and brightness. Their unique COB technology enables hundreds of LED chips to be encapsulated in the tiniest flexible circuit board. Combined with a phosphor layer on the LED Strip, it generates a continuous, uniformly bright light line along the entire length. There are no noticeable light spots compared with typical standard SMD LED strips. In our factory, COB LED strip is also called COB flexible LED Strip or FCOB LED Strip. Despite the single white color, we also have RGB COB LED strip. Just contact us immediately to get the latest prices.
Minimum yellow spots, higher color saturation, and a comprehensive range of CCT options with the best color consistency. You will feel more natural and comfortable under such a humanistic lighting environment.

Frequently Asked Questions
Do you want to see what kind of questions people always ask? Or do you want to find some replies to your questions? Suggest you don’t miss this part.
What are the difference between different series COB LED strips you have?
Our Basic Series COB strips are with 320chips/M, this series are the most cost-effective version, if you are looking for lowest prices, this can be a good choice for you.
Our Popular Series COB strips are with 420chips/M, this series are our best seller series. The design and prices are coming to a balance point.
Our High Efficiency Series COB strips are with 480chips/M, if you want lowest wattage while maximum lumens, this can be the best solution.
Our High Wattage Series COB strips are also with 480chips/M, if you want the maximum lumens without considering the power consumption. This can be the most suitable solution.
What is COB?
Chip on board (COB) is a method of circuit board manufacturing in which the integrated circuits (e.g. microprocessors) are attached (wired, bonded directly) to a printed circuit board, and covered by a blob of epoxy. By eliminating the packaging of individual semiconductor devices, the completed product can be more compact, lighter, and less costly. In some cases, COB construction improves the operation of radio frequency systems by reducing the inductance and capacitance of integrated circuit leads. For more details of this technology, you can check Wikipedia.
Are COB lights better than LED?
COB is also a type of LED, so this question does not make any sense. However COB LEDs have many advantages comparing with traditional SMD LEDs, you can continue read our FAQ as below.
What is the CRI of the COB LEDs which you are using?
The CRI of the COB LEDs which we are using are all more than 90Ra. Thus we also call our COB LED strip as High CRI COB LED strip. Generally speaking, CRI(colour rendering index) values 90 and above are considered to be excellent, however values below 80 are generally considered not good.
What are the advantages of COB LED strips?
There are a lot of advantages of COB LED strips including no lighting spots, better light, more flexible, more efficient, and etc. You can read our article for this.
Are COB LED strips brighter?
COB LED technology produces a considerably brighter light than traditional LED technology! They’re even more bright than high-density strips. Flip-chip LEDs, unlike SMD LEDs, are not enclosed in a plastic holder, therefore they produce dazzling, constant light from a broader angle. This enables them to generate light from the strip’s sides, which reaches more than 180 degrees. A wider light angle gives you more light, which is important for long-term brightness.
Are COB LED strip dimmable?
Yes, they are dimmable.
Do you have waterproof COB LED strip light?
Our standard COB LED strip light is IP20, we also have IP65, IP66, IP67, IP68 for choice. See below:
How do you pack the COB LED strips?
Our standard COB LED strips packages are:
Normally one reel COB LED strip is 5m, we have also other lengths for different series;
One reel COB LED strip is put into a ESD bag/Anti-static foil bag, also we have put a desiccant inside the bag;
25 reel of COB strips are put into one inner box carton;
4 inner boxes are put into one outerbox carton. So normally one carton will have 100reels COB strips.
How to install the COB LED strip light?
Clean the installation surface.
Measure the length you need to install, cut at the nearest cutting mark. For the remaining strip, weld at the next scissor mark to connect with other connection wire.
Do not pull the whole strip from the back release paper at one time. Do not hard press the LEDs.
Connect strip wire to the driver output side (Positive to positive, negative to negative.)
Connect the driver plug to wall socket.
Switch on and enjoy.
Do you offer aluminum profile for COB LED strips?
Absolutely, we offer various types aluminum profile with different sizes for our COB LED strips, the dimensions which we can offer include but not limited as below:
Sorry we have so many aluminum profiles, and it is not easy for us to put all here one by one.
