Lamp accessories encompass the supporting products that make lighting systems complete, functional, and properly maintained – components like sockets, adapters, dimmers, ballasts, transformers, repair parts, and various specialty items that connect bulbs to power, modify operation, enable repairs, and adapt fixtures for different bulb types. While bulbs get the attention, these accessories often determine whether a lighting system actually works, works safely, or can be adapted to meet changing needs. Having the right accessory available can mean the difference between a quick fix and replacing an entire fixture.

Sockets and lamp holders provide the critical interface between electrical power and bulbs. Various socket types match different base configurations: medium (E26) sockets for standard household bulbs, candelabra (E12) for chandelier bulbs, mogul (E39) for high-wattage lamps, bayonet sockets for various miniature and automotive bulbs, bi-pin sockets for halogen capsules and fluorescent tubes, and specialized sockets for unusual base types. Socket quality matters for safety and reliability – cheap sockets can arc, overheat, or fail prematurely, creating fire hazards or equipment failures. Quality sockets use appropriate materials (porcelain for high temperatures, weatherproof construction for outdoor use) and proper current ratings.

Adapters solve compatibility problems by allowing bulbs with one base type to fit sockets designed for different bases. Common examples include E26 to E12 adapters letting medium base bulbs work in candelabra sockets, E12 to E26 for the reverse, socket extenders that add length when clearance is limited, angle adapters that redirect the bulb axis, and various specialty adapters for unusual situations. Adapters should be properly rated for the bulb wattage and application – using an adapter not rated for the current or environment can create safety hazards.

Dimmers control light output by regulating voltage to bulbs, allowing adjustment from full brightness down to low glow or off. Modern dimmers come in various technologies: leading-edge dimmers for incandescent and halogen loads, trailing-edge dimmers for LED and electronic loads, 0-10V dimmers for commercial fluorescent systems, and smart dimmers with remote or app control. Proper dimmer selection matters – using an incandescent dimmer with LED bulbs can cause flickering, buzzing, or limited dimming range. The dimmer must be rated for the total load (add up all bulb wattages on the circuit) and matched to the bulb technology being controlled.

Ballasts regulate current through fluorescent and HID lamps, providing the starting voltage and operating current these discharge lamps require. Electronic ballasts for fluorescent tubes provide instant-on, flicker-free operation, improved efficiency, and silent operation compared to older magnetic ballasts. HID ballasts must be matched to lamp type (metal halide, HPS, mercury vapor) and wattage – they're not interchangeable. Ballast failure is a common cause of fluorescent and HID fixture problems, and knowing when to replace the ballast versus replacing the entire fixture involves economics and fixture age.

Transformers (for low-voltage halogen lighting) and LED drivers (for LED fixtures and bulbs) convert line voltage to the operating voltage lighting requires. Low-voltage halogen transformers step down 120V to 12V or 24V for halogen track lighting, landscape lighting, and under-cabinet systems. Electronic transformers work well with halogen but may not be compatible with LED replacements. LED drivers convert AC line voltage to the DC low voltage and regulated current LEDs require, with dimming compatibility varying by driver design. Transformer/driver sizing matters – undersized units don't provide adequate power, oversized units waste money.

Repair and maintenance accessories include various specialty items: ceramic sockets for high-heat applications, outdoor weatherproof sockets, socket reducers and enlargers, cord switches for lamps, pull chains, cluster bodies for multiple-socket fixtures, cord sets and lamp parts for fixture repair, wire connectors sized for lighting applications, and numerous other components. These accessories enable repair and customization rather than replacement – often at a fraction of fixture replacement cost.

Installation accessories include hanging hardware, cord management systems, mounting brackets, wire management, conduit and fittings, junction boxes, and various items that facilitate proper installation. While not as exciting as bulbs, proper installation accessories ensure safe, code-compliant, attractive installations.
