Track Lighting & Track Heads

Track lighting puts multiple adjustable heads on one powered rail, so light aims exactly where retail displays, artwork, or kitchen counters need it - and reaims later without rewiring. The one trap is compatibility: track comes in three incompatible standards, and a head built for one won't seat in another. Match the head to the track, and the rest is layout. Lumera Electric carries track sections, heads, and connectors across the major systems.

Track Lighting & Track Heads

What's the difference between H, J, and L track?

Three incompatible standards exist, named for the brands that set them. H (Halo), J (Juno), and L (Lightolier) each position the conductors differently inside the track channel. Because the contact geometry differs, a head or connector built for one won't seat in another. Identify which standard your existing track uses before ordering heads or sections.

Are track heads interchangeable between brands?

Not across standards. A track head only seats in track of the same standard — H heads on H track, J on J, L on L. Within a standard, heads from different makers usually interchange, since the connector is shared. Many heads are sold as standard-specific, so confirm H, J, or L before mixing brands.

Fixed, monorail, or flexible — which track form?

It's about how the track bends. Fixed (linear) track is rigid and runs straight, the most common and economical. Monorail is a heavier rail, often standoff-mounted, that can be field-bent into curves. Flexible track bends by hand into gentle shapes for accent runs. Pick fixed for rows, monorail or flexible for curved layouts.

What is single-circuit versus 2-circuit track?

Circuits decide independent switching. Single-circuit track powers every head together from one switch — the default for general accent rows. 2-circuit (dual-circuit) track carries two separate feeds in one rail, so two groups of heads switch or dim independently. Use 2-circuit when one track has to light two scenes.

How do I plan a track layout — sections, connectors, and power feeds?

Start with the power feed location, where the track ties to the branch circuit. From there, straight sections extend the run, and L, T, and X connectors turn corners or branch it. A floating (canopy) feed powers a track with no ceiling box nearby. Cap open ends with dead ends, and total the heads against the track's wattage rating.
