Flashlights are popular promotional giveaways because they offer durability, usefulness, and a variety of sizes and price points. We’ve expanded, and improved, our light-up product category with the addition of chip-on-board (COB) lighting.

COB technology is a new form of LED packaging that produces brighter light from a smaller space. Here’s the low-down on how COB technology works and why customers increasingly choose COB flashlights for promotional items.

How COB technology works

In basic terms, COB lights are nine or more LED chips, or diodes, attached to a surface to form a single line. The LED chips used in COB lights are packaged differently from other LEDs, making it possible for the chips to be set closer together so that the amount of space they take up is reduced, but they still illuminate a wider area.


Benefits of COB technology

There are many benefits to using COB technology. The lights are more energy efficient and have a longer shelf life. Additionally, flashlights using COB technology offer a higher lumen rating in a smaller size compared to flashlights with fluorescent light bulbs. This means a smaller-than-traditional flashlight creates a brighter light. Finally, thanks to requiring less space, COB packaging offers more flexibility with product design.


Longer usage equals longer branding time

Adding COB technology to flashlight promotional items means your giveaways will last longer for the recipient and work longer as a branding tool for you. The longer a promotional product is kept, the more impressions your marketing message makes. Did you know that more than 80 percent of people keep promotional products (PDF) for more than one year? COB flashlights are the perfect example of a long-lasting item with a long shelf life to keep your brand within reach and top of mind.
