Tungsten Halogen Lamp
Unknown
The Tungsten Halogen Lamp is a type of incandescent lamp that uses a tungsten filament enclosed in a halogen gas environment to produce a bright, long-lasting light output used in a wide variety of applications including automotive, commercial, and residential lighting. It is classified as FDA Not Classified (Class N) with product code RHB and is GMP-exempt. This product has no associated regulation number or medical specialty, as it is a general-purpose illumination device. No implant or life-sustaining flags are noted. FDA oversight applies under electronic product radiation control provisions for light-emitting products.
No 510(k) clearances found for "RHB". Try a different K-number, product code, or device name.
What is a Predicate Device?
A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
