Engineering Architecture & Low-Voltage Design

The G50-39L35 series is a heavy-duty low-voltage LED globe lamp specifically designed for off-grid direct current (DC) installations where conventional mains voltage (110V/220V) cannot be deployed. Featuring a classic G50/A50 rounded envelope (Φ50mm × 88mm), this bulb delivers 500 lumens of continuous, flicker-free illumination at an ultra-low energy consumption of just 5.0 watts.

The thermal foundation combines an aviation-grade aluminum collar with a robust optical glass dome. An internal radial tower chassis supports 39 precision-binned SMD 2835 LEDs, producing true 360-degree omnidirectional light distribution without dark zones, making it ideal for table fixtures, ceiling fixtures, and marine interior compartments.

Specialized Low-Voltage Power Domains & Applications

Engineered for extreme reliability, the G50-39L35 provides discrete voltage configurations optimized for distinct industrial and off-grid power ecosystems:

  • 6-12VDC Range: Tailored for portable emergency battery kits, low-voltage inspection desk lamps, and small off-grid setups.
  • 10-36VDC Range: Universal compatibility for 12V and 24V marine boat cabins, living quarters, solar battery banks, and remote telecommunication cabins.
  • 48-80VDC Range: Industrial grade power input suited for telecom base stations, data center emergency backup systems, and specialized high-voltage DC networks.
  • Specialized UV Spectrum: Available in targeted ultraviolet wavelengths for specialized curing, counterfeit detection, and industrial fluorescence inspection.

Frequently Asked Questions

Can this G50 LED bulb be connected to standard 110V or 220V AC household mains power?
NO. This is strictly a low-voltage DC bulb designed for 6-12V, 10-36V, or 48-80V DC power systems. Connecting this bulb directly to standard 110V/220V AC mains electricity will cause immediate electrical damage and voids the warranty. Always verify your circuit voltage before installation.
What is the mechanical difference between the E27 and B22 base options?
E27 is a 27mm Edison screw base where the bulb threads into the socket clockwise. B22 is a 22mm bayonet cap base featuring two opposite locking pins that push and twist into place. Both share the exact same Φ50mm × 88mm glass globe dimensions and internal driver specs.
What off-grid and industrial systems are suitable for the 48-80VDC configuration?
The 48-80VDC version is engineered specifically for stationary industrial applications including -48V telecommunication central offices, mobile base station shelters, off-grid solar energy storage battery rooms, and data center DC backup lighting circuits requiring high-reliability low-voltage globe lamps.
What is the factory minimum order quantity (MOQ) and custom packaging policy?
Standard stock configurations are available from 5 pairs for evaluation and distributor sample testing. For custom branded packaging (such as printed color retail boxes or blister packaging), the printing MOQ is 5,000 units. The client pre-funds the custom packaging, which is warehoused in our Dongguan plant and drawn down across recurring orders.
