Lighting has become a major focus in interior design. While you have endless choices, panel and COB lights are commonly used in most spaces. Let\u2019s take you through the panel light vs COB light<\/b> guide.
\n<\/span><\/p>\n

    \n
  1. \n

    Design:<\/h2>\n

    Panel light gets its name from slim, flat and square, circular or rectangular design. It uses LED technology and is a good replacement for conventional bulbs.
    \n<\/span>
    \nThe COB light full form<\/b> is Chip on Board. It also uses LED technology but in the form of multiple LED chips arranged together on a single circuit module.<\/li>\n

    <\/span><\/p>\n

  2. \n

    Aesthetics:<\/h2>\n

    Panel light has a thin and sleek design that enables it to blend seamlessly into ceilings. The aesthetic appeal is better.
    \n<\/span>
    \nCOB light has compact size. The installation is visible but with high functional value.<\/li>\n

    <\/span><\/p>\n

  3. \n

    Light Output:<\/h2>\n

    The panel light provides diffused and soft illumination. It has a broad beam angle for uniform distribution of light. Hence, it is ideal for large spaces.
    \n<\/span>
    \nCOB light delivers high-intensity illumination. The beams are narrow, focused and give extra brightness. It is suitable to give the spotlight to a particular object or area.<\/li>\n

    <\/span><\/p>\n

  4. \n

    Applications:<\/h2>\n

    Panel light is used in living rooms, kitchens, hospitals, classrooms and other commercial and industrial spaces.
    \n<\/span>
    \nCOB light is used for decorative accessories, plants, artwork, galleries, or corridors. It also has applications in retail displays, stadiums, photography, street lighting and the automotive industry. Downlights and floodlights also use COB lights.<\/li>\n

    <\/span><\/p>\n

  5. \n

    Fixture:<\/h2>\n

    Panel light is commonly mounted on ceilings – surfaced, suspended or recessed.
    \n<\/span>
    \nCOB light has versatile fixture options. It can be mounted on ceilings, walls and poles.<\/li>\n

    <\/span><\/p>\n

  6. \n

    Energy Efficiency:<\/h2>\n

    While both panel and COB lights are more energy-efficient than traditional lights, there is a noticeable difference in their power consumption.
    \n<\/span>
    \nCOB light\u2019s per lumen output is more efficient than its panel counterpart. Hence, COB light consumes less power too.<\/li>\n

    <\/span><\/p>\n

  7. \n

    Heat Generation:<\/h2>\n

    The large surface area of panel lights makes them generate low to moderate heat.
    \n<\/span>
    \nOn the contrary, since COB light has a compact size, it generates high heat. They need better heat sinks (passive heat exchanger to avoid overheating).
    \n<\/span>
    \nDespite their different heat generation, they are both thermally efficient than other light options.<\/li>\n

    <\/span><\/p>\n

  8. \n

    Cost:<\/h2>\n

    Panel light is somewhat more affordable than COB light. The reason is that COB light gives higher lumen output, which increases its price factor.<\/li>\n

    <\/span><\/p>\n

  9. \n

    Lifespan and Durability:<\/h2>\n

    The panel light has a slightly lesser lifespan and durability than the COB light.
    \n<\/span>
    \nThe construction of a panel light is complex due to the large surface area. It has a lifespan of 30,000 to 40,000 hours.
    \n<\/span>
    \nCOB light is made from fewer but more durable components and covers only a small area for illumination. It can last for up to more than 50,000 hours.<\/li>\n<\/ol>\n

    Types of LED Lights<\/h2>\n

    Apart from panel and COB lights, there are several other types of LED lights you can consider:<\/p>\n
