Low-Voltage LED Bulbs Series
Low-voltage LED bulbs for 12V/24V DC systems, RVs, off-grid and industrial DC lighting. Factory direct wholesale, OEM/ODM.
Low-Voltage G4 LED Bulbs: 12V / 24V / 48V Halogen-Replacement Disc & Capsule Lamps
Low-voltage LED bulbs replace halogen capsule and disc lamps in downlights, cabinet lighting, and DC-powered installations. MIDCARS' G4 bulbs deliver 2.5W / 250LM (equivalent to a 20–25W halogen) in a compact pin-base design, with a comprehensive discrete voltage range covering 12V, 24V, and 48V DC — ideal for off-grid solar, DC distribution, and fixed low-voltage systems.
Choosing by Voltage and Pin Type
| Voltage | Typical application |
|---|---|
| 12V DC | Residential and commercial low-voltage downlights, cabinet lighting |
| 24V DC | DC lighting circuits and low-voltage track systems |
| 48V DC | Telecom -48V, data-center DC power, solar off-grid storage, industrial control |
How to Choose the Right G4 LED Bulb
- Confirm the voltage. Match the bulb to your DC supply — 12V, 24V, or 48V — to avoid over-voltage failure.
- Pin type. Back-pin or side-pin G4 — check your fixture's pin orientation.
- Beam pattern. Choose 360° omnidirectional for general wash, or a disc type for a focused downlight pattern.
- Brightness. 250LM replaces 20–25W halogen in most fixtures.
Common Applications
- Residential and commercial low-voltage downlights
- Cabinet, shelf, and display lighting
- Solar off-grid and DC-powered installations
- Telecom, data-center, and industrial control DC lighting

What replaces a 20–25W halogen G4 capsule?
Our 2.5W / 250LM G4 LED replaces 20–25W halogen capsules in downlights and cabinet fixtures, using far less power and running much cooler.
Can I use a 48V G4 bulb in a solar system?
Yes. The 48V version suits solar off-grid storage and DC distribution, where it runs directly on the battery bus without a separate driver.
What is the difference between back-pin and side-pin G4?
The pin orientation differs — back-pin connects from behind the capsule, side-pin from the side. Match the pin type to your fixture to ensure correct contact.
What is your minimum order quantity?
Standard stock starts from 5 pairs for testing. For custom packaging, the packaging run has a 5,000-piece MOQ, pre-funded and drawn down across repeat orders. Contact sales02@zhishanled.com for a quotation.
