Frequently Asked Questions
What is the maximum continuous run length for this SOB LED strip?
This ultra-long LED strip features a special design allowing for a maximum continuous run of 10 meters with power fed from only one side, simplifying installation.
What are the key benefits of the SOB technology in this strip?
SOB (System-on-Board) technology ensures high bending reliability and a wider 180° beam angle, coupled with excellent flexibility and strong bending resistance for diverse applications.
Is this LED strip suitable for dimming, and what voltage does it require?
Yes, this LED strip is dimmable. It operates on a 24V input voltage with constant current (IC regulated) for stable performance.
Can this specific LED strip model be customized for higher power outputs?
Yes, while featuring built-in chip protection stents for higher power, special power requirements beyond the standard range are customizable upon request to DENO LED.
Is this SOB strip light also called FOB, S-COB or COB Pro strip light?
Yes. Model 15904 belongs to the DENO SOB (Spot on Board) family, which the market also calls FOB strip light, S-COB strip light or COB Pro strip light. All three names describe the same dot-free chip-on-board LED strip construction, so you can quote it under whichever term your project specification uses.

SOB is the upgraded generation of the COB LED strip
Every SOB board on this page starts from the classic COB recipe — one continuous phosphor line, zero visible dots — and rebuilds it with individually encapsulated, gold-wire-bonded packages soldered on thick copper of up to 105 µm or thicker. The result keeps the COB look while DENO has verified builds up to 24W/m at 24V DC (25 °C ambient, aluminum profile), with a standard binning target of SDCM ≤3; CRI, run length and cut unit are model-specific. For shorter, lower-load or cost-sensitive lines the classic COB range remains a practical choice — compare exact models under equal conditions.
