Product Overview
The Satco S3142 150T3Q/CL/118MM Lamp is a commercial-grade, line-voltage double-ended tungsten halogen linear lamp engineered for high-intensity security floodlights, portable worksite quartz lamps, architectural wall washers, and studio/theatrical staging. Operating at 150 watts directly over a standard 120V line circuit, this high-performance clear quartz tube projects 2,400 initial lumens of crisp 2900K warm white illumination. Outfitted with an industry-standard R7s recessed single-contact base with 118mm pin spacing and a heavy-duty C-8 linear filament core, it provides a flawless 100 CRI color index profile over a reliable 1,500-hour rated average service life.

ADL Supply Expert Application & Replacement Guide
The Satco S3123 line-voltage linear halogen tube is an established property maintenance standard specified heavily by commercial facility managers, electrical contractors, and worksite safety crews. This double-ended T3 series module is engineered explicitly to slide into high-lumen outdoor security fixtures, portable worksite construction towers, architectural building facade washers, and stage/studio backdrop setups requiring a high-output, full-spectrum incandescent source to map visual environments with total clarity (100 CRI).
Critical Linear Dimension Validation and Socket Tension Requirements: A major driver of warehouse shipping returns is miscalculating structural bulb length. This lamp features an **R7s recessed single contact base configuration with an exact 118mm contact-to-contact spacing (approx. 4.69 inches)**. It is entirely non-interchangeable with shorter 78mm linear tubes (approx. 3.12 inches) that share the same contact profile shape. Attempting to fit this bulb into a short housing canopy will break the quartz pinch seals.
Furthermore, because these tubes operate at intense thermal levels, the spring-loaded contacts inside the fixture's R7s lampholders must be inspected closely. Weak spring tension or carbonized contact pits create high electrical resistance points, triggering localized heat loops that cause the ends of the tube to melt or warp prematurely.

Verify Before Ordering
Direct Line Voltage 120V & 118mm Length Check — California Shipping Restrictions Apply
This bulb operates on standard 120V main lines and does NOT require an external low-voltage transformer. Please physically measure your fixture's clip distance to confirm it is sized for a 118mm length tube rather than a short 78mm variant before checkout. This is an unshielded quartz tube; national life safety codes mandate installation strictly inside approved fixtures incorporating a tempered glass safety shield lens to safely contain fragment loops and block unfiltered shortwave UV rays in the event of high-pressure bursts.
State Delivery Restriction: Due to California Title 20 efficiency regulations, this high-wattage tungsten halogen lamp cannot be legally sold or shipped to residential or commercial destinations inside California. |

Operation, Safety & Mounting Compliance
Line Voltage Filtration and Dimming Control Tracks
This line-voltage halogen bulb provides instant-on ignition with zero warm-up delays and is natively 100% dimmable across traditional analog dimming networks. Lowering current paths shifts the axial tungsten coil loop into a cozy amber spectral temperature. Because this lamp handles an intensive thermal power draw, ensure all socket wiring pathways utilize heavy duty, heat-resistant silicone or high-temperature fiberglass braided sleeving to prevent internal conductor lines from baking or cracking over extended operations.
Quartz Glass Preservation and Contamination Prevention
Never handle the clear quartz glass envelope body wrapper with bare fingers during installation sweeps. Human skin cells deposit microscopic alkaline body oils that fuse chemically to the quartz wall structure during rapid heating cycles. This contamination blocks essential heat dissipation, creating intense localized hot spots that trigger accelerated envelope devitrification, early structural clouding, micro-fracturing, and premature blowout under internal high-pressures. Installers must execute re-lamping sweeps using clean cotton tech gloves, a lint-free microfiber cloth, or its protective cardboard package sleeve. Clean meticulously with isopropyl alcohol if accidental baseline skin tracking takes place. Turn off circuit breakers and allow a 20-minute cooling intermission before performing maintenance loops to prevent contact skin burns.
