Technical Specs & Certifications
LED light bulbs for motorhomes require specialized technical specifications to address the unique demands of recreational vehicle environments, including limited power resources, vibration exposure, variable ambient conditions, and the need for accurate color rendering during extended living. At Beauty STC Manufacturing Co., Ltd., we engineer our motorhome LED bulbs to exceed industry standards in critical performance areas while ensuring robust reliability.
Lumens per Watt efficiency is paramount due to the reliance on battery or limited generator power in motorhomes. Our standard A19 and PAR30 replacement bulbs for 120V AC systems deliver a minimum of 110 lumens per watt, with premium models achieving 120-130 lumens per watt under controlled LM-79 testing conditions at 25°C ambient temperature. This high efficacy directly translates to extended battery life during off-grid operation, reducing the frequency of generator use. For example, our 9W PAR30 flood bulb replaces 65W halogen equivalents while producing 1100 lumens, and our 8.5W A19 standard bulb outputs 800 lumens. We achieve this through optimized thermal management using aluminum heat sinks and high-efficiency driver circuits designed specifically for the voltage fluctuations common in RV electrical systems.
Color Rendering Index performance is non-negotiable for motorhome living where accurate color perception affects everything from food preparation to interior aesthetics. All Beauty STC motorhome LED bulbs maintain a minimum CRI of 92, with most models rated at 94-95 as measured per IES TM-30-15 methodology. This exceeds the customer-specified >90 requirement through our proprietary multi-phosphor blend and strict binning processes during manufacturing. The high R9 (saturated red) values above 50 ensure vibrant, natural rendering of skin tones and food, critical for the close-quarters living environment of a motorhome where artificial lighting dominates for extended periods.
IP rating requirements must account for the specific installation zone within the motorhome. For wet locations such as bathrooms and kitchens where direct water exposure may occur during cleaning, Beauty STC bulbs carry a minimum IP44 rating, protecting against splashing water from any direction and solid objects larger than 1mm. Dry area applications like bedrooms and living compartments utilize IP20-rated bulbs, sufficient for dust protection in enclosed fixtures while maintaining optimal thermal performance. It is critical to note that the IP rating applies to the complete bulb assembly when installed in a compatible fixture – we explicitly avoid misleading claims of IP67 for standard replacement bulbs as the socket interface cannot achieve full submersion protection. Our engineering team validates ingress protection through IEC 60529-compliant testing protocols, including extended vibration testing that simulates 500,000 miles of road travel to ensure seal integrity.
Beauty STC’s commitment to quality is embedded in every motorhome bulb through our triple-validation process. Each product undergoes 100% automated optical testing for lumen output and chromaticity, followed by 100% high-potential electrical safety testing, and batch-level accelerated life testing to 50,000 hours at elevated temperatures. Our proprietary shock-absorbing internal mounting system prevents filament failure under vibration, while conformal-coated drivers resist moisture ingress even in coastal environments. All bulbs carry UL 1993 and CSA C22.2 No. 250.0 certifications with full traceability through our ISO 9001:2015-certified manufacturing facility. This rigorous approach ensures consistent performance where reliability isn’t just preferred – it’s essential for traveler safety and comfort during extended journeys.

Application Scenarios
LED light bulbs designed specifically for motorhomes serve critical functions within the vehicle itself and are not intended for installation in fixed commercial structures like hotels, malls, or offices. The environments, electrical systems, and operational requirements differ significantly. Motorhome lighting must address unique challenges such as 12V DC electrical systems, constant vibration, limited space, thermal constraints, and the need for extreme energy efficiency to preserve battery life. Using standard household or commercial LED bulbs in a motorhome is generally ineffective and potentially unsafe due to voltage incompatibility and mechanical fragility.
Within a motorhome, LED bulbs are essential across nearly all interior lighting applications. Primary locations include the main living area for ambient and task lighting, the kitchen for under-cabinet illumination and overhead cooking light, the bathroom for mirror lighting and general illumination, sleeping compartments for reading lights and mood lighting, hallway or corridor areas for safe nighttime navigation, and storage compartments for visibility when accessing gear. Exterior applications are also common, such as entry steps, awning lights, and exterior utility lighting, though these often require dedicated sealed fixtures rather than simple bulb replacements.
Installation requires careful attention to motorhome-specific factors. Always verify the bulb base type matches the existing socket, commonly wedge base (e.g., DE36D, 7506), bayonet (e.g., BA9s), or bi-pin (e.g., G4, G9) types, and ensure the bulb is explicitly rated for 12V DC operation; standard 120V AC household bulbs will fail immediately. Prioritize bulbs with robust construction featuring shock-resistant filaments or solid-state designs and integrated vibration dampening, as constant road vibration is the leading cause of premature failure in RV lighting. Avoid bulbs generating excessive heat, particularly in enclosed or plastic fixtures common in motorhomes, as thermal buildup can warp sockets or housings; look for designs emphasizing thermal management. If replacing existing halogen bulbs, confirm compatibility with any existing dimmer switches, as many RV dimmers are not LED-compatible and may cause flickering or reduced lifespan without a suitable bulb. For newer motorhomes with CAN bus electrical systems, select bulbs specifically labeled as CAN bus compatible to prevent error messages or flickering caused by the low current draw of LEDs. Finally, ensure all connections are secure and wires are properly routed away from sharp edges or heat sources to prevent shorts, given the vehicle’s movement. Never install motorhome-specific 12V LED bulbs into standard household or commercial 120V/230V AC fixtures found in hotels, malls, or offices, as they will not function and pose a safety hazard.
