Technical Specs & Certifications
Beauty STC Manufacturing Co., Ltd. designs and manufactures LED bulbs specifically engineered to meet the demanding operational environment of motorhomes and recreational vehicles. Our technical specifications prioritize reliability, efficiency, and visual comfort under challenging conditions, directly addressing the core requirements of mobile living spaces. We achieve this through rigorous material selection, advanced thermal management, and adherence to stringent quality control protocols throughout our manufacturing process at our ISO 9001-certified facility.
Lumens per Watt (lm/W) efficiency is critical for motorhome applications due to reliance on limited battery and alternator power. Beauty STC LED bulbs consistently deliver 110-130 lm/W across our standard A19 and PAR30 motorhome product lines. This high efficacy is achieved using premium Epistar or Samsung LED chips coupled with optimized driver circuitry operating at 90%+ efficiency. Crucially, our thermal management system, featuring aluminum MCPCB substrates and proprietary heat-dissipating housing designs, ensures this lumen output remains stable even in the elevated ambient temperatures common within motorhome ceiling cavities during summer operation, preventing the lumen depreciation seen in poorly designed competitors’ products.
Color Rendering Index (CRI) is paramount for creating a comfortable and functional living environment where accurate color perception matters for cooking, grooming, and interior aesthetics. All Beauty STC motorhome LED bulbs are engineered to exceed the CRI >90 requirement, with our standard offering achieving Ra 92-95. This is accomplished through the use of high-quality dual-phosphor LED packages and precise spectral tuning during manufacturing. We avoid cheaper single-phosphor solutions that often fall below CRI 85, ensuring that skin tones appear natural, food looks appetizing, and interior fabrics retain their intended colors, significantly enhancing the user experience within the confined space of a motorhome.
IP (Ingress Protection) Rating is non-negotiable for motorhome lighting due to exposure to moisture, dust, and potential water splashes in wet zones like galleys and bathrooms. Beauty STC provides differentiated IP protection based on application: bulbs intended for dry interior areas (bedrooms, living spaces) meet IP44 (protected against solid objects >1mm and splashing water from any direction), while our dedicated wet-location bulbs for galleys, bathrooms, and exterior porch lights achieve IP67 certification (complete dust tightness and protection against temporary immersion up to 1 meter for 30 minutes). This is realized through fully potted driver electronics, seamless silicone gasketing at the lens-base interface, and corrosion-resistant housings, all validated through accelerated environmental testing including 500-hour salt spray exposure per ASTM B117 standards.
Beauty STC’s commitment to quality is evident in every bulb. We utilize only automotive-grade components rated for extended temperature ranges (-40°C to +85°C ambient), implement 100% automated optical and electrical testing during production, and subject finished goods to a 48-hour continuous burn-in test to eliminate infant mortality failures. Our bulbs undergo rigorous vibration testing per ISO 16750-3 standards to withstand road conditions, feature wide input voltage tolerance (9-30V DC) to handle motorhome electrical system fluctuations, and incorporate flicker-free drivers (<5% flicker percent) to prevent visual discomfort during motion. Backed by a comprehensive 5-year warranty, Beauty STC LED bulbs deliver the sustained performance, visual quality, and rugged reliability that discerning motorhome manufacturers and owners demand, setting the industry benchmark for mobile lighting solutions.

Application Scenarios
LED bulbs designed specifically for motorhomes serve critical functions within the vehicle itself and have no direct application in commercial settings like hotels, malls, or offices. Motorhomes operate on low-voltage DC electrical systems (typically 12V or 24V) fundamentally different from the AC mains power used in commercial buildings. Installing motorhome-specific LED bulbs in hotels, malls, or offices would be incompatible, unsafe, and ineffective due to voltage mismatch and lack of necessary safety certifications for those environments. The intended and appropriate use for these bulbs is exclusively within the motorhome’s interior and sometimes exterior lighting circuits.
Within the motorhome, key application areas for appropriately rated 12V/24V LED bulbs include the main living area ceiling fixtures for general illumination, the kitchen counter and overhead spots for task lighting during food preparation, reading lamps above seating or bed areas for localized light, bathroom vanities and mirrors for grooming, wardrobe and storage compartment lighting for visibility, and hallway or stairway path lighting for safety. Exterior applications might include awning lights, porch lights, or entry step illumination, but these require bulbs specifically rated for outdoor use with appropriate IP protection against moisture and dust. Using standard household AC LED bulbs in a motorhome is dangerous and will cause immediate failure due to the DC voltage; only bulbs explicitly designed for 12V/24V DC systems must be used.
Installation requires careful attention to the motorhome’s unique environment. Always disconnect the motorhome’s house battery or isolate the relevant circuit at the fuse box before beginning any work to prevent short circuits or electrical shock. Verify the bulb base type matches the fixture socket exactly such as G4, G5.3, E14, or BAY15d as incorrect bases cause poor contact or damage. Pay strict attention to polarity when installing wedge-base bulbs like festoon or some G-types; reversing positive and negative leads will prevent the bulb from functioning. Ensure adequate ventilation around the bulb, especially in enclosed fixtures, as excessive heat buildup significantly shortens LED lifespan despite their lower heat output compared to halogens. Confirm the total wattage of all bulbs on a single circuit does not exceed the fuse rating or the capacity of the wiring, as overloading can blow fuses or damage the electrical system. For high-vibration areas like near engines or suspension points, select bulbs explicitly rated for automotive/marine use which have reinforced filaments or internal potting to withstand constant movement. Finally, avoid using adhesive-backed LED strips near heat sources like stoves or heaters as the adhesive can fail, and ensure any strips used comply with low-voltage safety standards for the vehicle. Proper selection and installation maximize energy efficiency, extend battery life between charges, and ensure reliable lighting during travel and stationary use.
