SPL Lighting G4 LED bulbs

spl lighting g4 led bulbs formats and output classes

G4 two-pin capsules serve furniture spots, plinth lights, mini downlights, and tight chandeliers. Bodies include ultra-compact silicone “sticks”, flat disc PCBs for forward throw, and tower styles where a bit more centre intensity is needed. Usual power nodes: 1.2 W, 1.8 W, 2.5–3 W, and 4 W. Expect roughly 100–450 lm depending on optic and CCT. Colour packs 2700 K / 3000 K / 4000 K; CRI 80 as the workhorse with CRI 90 (often R9 > 50) for wood, food, textiles, and skin tones. Thermal targets are conservative: keep Tc ≤ 85 °C and give even the small capsules a metal path or free air.

spl lighting capsule led lamps optics and builds

Disc types push ~110–140° forward for shelves and task nooks; silicone capsules read ~270° for “sparkle” in multi-arm fittings; tower variants deliver a tighter hot spot inside tiny shades. Binning on project lots lands within ≤3 SDCM so colours track across phases. Clear encapsulant gives punch; opal jackets calm surface luminance for eye-level sconces and mirrors. Overall lengths span ~25–38 mm on micro capsules and ~35–45 mm on short discs—check throat and cage clearance before lock-in.

spl lighting low voltage g4 lighting drivers and dimming

All lamps are 12 V nominal. Many accept AC/DC; some are DC-only (polarity marked on the body). Legacy electronic transformers demand a minimum load and specific dimmers; lightly loaded channels behave better on a dedicated 12 V constant-voltage LED driver. Dimming is primary-side phase-cut; trailing-edge (RC) runs quieter and extends life. Low-end stability is a load game: aggregate a few heads per channel or add the specified bleed to stop shimmer. Surge ride-through sits ~0.5–1 kV—fit an upstream SPD where motors live on the same board.

spl lighting g4 retrofit lamps fitment and selection

Pins follow IEC 60061 (2-pin, 4.0 mm pitch). Use heat-rated lampholders (≥ T120…T150) in enclosed cups; avoid insulation or fabric touching the crown. Discs often stand 9–13 mm proud of the holder—verify lens and shade clearance. On DC-only SKUs, respect polarity; on AC/DC capsules, keep secondary runs short to limit voltage drop (≤0.5 V preferred on 12 V).

Technical references and life data

LED modules: EN/IEC 62031. Control gear inside lamp: EN 61347-2-13 with IEC 62384 performance. Lamp safety/marking (where applicable): EN/IEC 62560. EMC: EN 55015 / EN 61547. Photobiological safety: EN 62471 RG0/RG1 on typical outputs. Source packages are LM-80 qualified with TM-21 projections—L70/L80 commonly 25–35k h on micro capsules and up to ~50k h on thermally loaded discs at Ta 25 °C.

Application mapping, with real numbers

• Joinery shelves and plinths: disc 3000/4000 K, 200–300 lm, forward throw onto the work surface.
• Chandeliers and crystal: clear capsule 2700 K, 150–250 lm, CRI 90 for warm sparkle.
• Display cases: tower 3000 K, 250–350 lm with low flicker metrics where cameras are present.
• Boats/RVs: AC/DC capsules tolerate small inverters; check ripple if radios sit nearby.

Series snapshot

Mini capsule (smallest footprint), flat disc (forward output), tower (higher centre intensity), and decor capsule (tinted/opal shells for visible lamps). These four cover 95% of fittings without changing trims.

Selection checklist for planners

1. Beam intent: omni capsule for sparkle vs disc for forward task.
2. Lumen node: 150–250 lm decorative arms; 250–400 lm small task heads.
3. Colour/CRI: 2700 K for lounge/dining, 3000 K mixed, 4000 K mirror or display; specify CRI 90 where materials matter.
4. Driver path: LED-rated transformer with adequate minimum load, or a dedicated 12 V CV driver per group.
5. Dimming: trailing-edge preferred; declare dimmer type and minimum level on drawings.
6. Geometry/thermal: overall height, throat diameter, holder T-class, airflow around the crown.

Integration notes and spares
These capsules drop into the brand’s miniature holders, roses, and keyed low-voltage connectors. Keep a small drawer of gaskets, cord grips, and replacement lenses; diffusers are the first to get scratched late in a program.

In specs that group tiny sources as spl lighting miniature led bulbs, add envelope type (capsule/disc/tower), lumen class, and dimmer topology on a single line—teams pull the right carton first time. For room lists that loosely say spl lighting small led lights, include overall length and “enclosed-fixture suitable” where shades run hot. When a heritage brief calls for sparkle language like spl lighting decorative g4 bulbs, choose clear shells at 2700 K, CRI 90, and keep channel loads healthy for smooth low-end.
