Satco S11661 12T8/LED/36-5CCT/DIM/LF/BP

Satco S11661 12W T8 LED – Up to 1550 lm | 3000K–6500K 5-CCT Selectable | Type B Ballast Bypass | 3′ (36″)

The Satco S11661 is a 12W LED T8 linear lamp, 3′ (36″) nominal length, with a Type B ballast-bypass design that operates on 120V–277V range voltage with no ballast or external driver required. It is field-selectable across five color temperatures — 3000K, 3500K, 4000K, 5000K, and 6500K — with output ranging from 1450/1500/1550/1550/1500 lumens depending on the CCT selected, and is a direct replacement for a 25W fluorescent T8 tube. The PET-coated shatterproof construction makes it suitable for food service environments, and optical flicker is rated below 2%. Please verify specifications below before ordering.

Technical Specifications

Product Overview

The Satco S11661 is a Type B ballast-bypass LED T8 lamp designed to directly replace a 25W linear fluorescent T8 tube after the existing ballast is removed and the fixture is rewired for direct line voltage. With 120V–277V range voltage compatibility, this lamp works across a wide variety of commercial fixture types without requiring a separate external driver.

A standout feature of this lamp is its 5-CCT selectable design: installers can choose between 3000K, 3500K, 4000K, 5000K, or 6500K at the time of installation using the lamp's built-in CCT selector, rather than stocking separate SKUs for each color temperature. Optical flicker is held below 2%, and the PET-coated shatterproof tube construction is built for safety in food service environments such as commercial kitchens.

Rated for 50,000 hours of life and backed by a 5-year warranty, this lamp is dimmable down to 10% in 120V applications only (277V installations are not dimmable), and is rated for damp locations and enclosed fixtures — though not fully enclosed vapor-tight fixtures.

Compatible Applications

• Commercial kitchens and food service facilities
• Offices
• Retail spaces
• General commercial and industrial T8 fixtures (ballast removed/bypassed)

Before Ordering – Verify

• This is a Type B ballast-bypass lamp – the fixture's existing ballast must be removed and the tombstones rewired for direct line voltage before installation; it will not operate in an unmodified fixture with the ballast still in place
• Confirm the fixture is wired for the correct line voltage (120V or 277V) within the lamp's 120V–277V range
• If dimming is required, confirm the application is 120V (dimmable down to 10%) – this lamp is not dimmable at 277V, and not all dimmers are compatible
• Confirm CCT selection method/location on the lamp before installation, since color temperature is field-selectable rather than fixed
• Confirm wattage and nominal length match the application: 2′ (S11660, 7W), 3′ (S11661, 12W), and 4′ in five lumen/wattage tiers (S11662 9.5W, S11663 10.5W, S11664 11.5W, S11665 15W, S11666 18.5W)
• Not for use in fully enclosed vapor-tight fixtures
• If a DLC listing is required for utility rebate eligibility, confirm the current QPL listing for this specific wattage with ADL Supply before ordering

Safety and Installation Guidelines

• Disconnect power and fully remove or bypass the existing fluorescent ballast before installing this lamp – do not install into a live, unmodified ballasted fixture
• Verify correct line-voltage wiring at the tombstones (120V–277V) before energizing the fixture
• Do not install in fully enclosed vapor-tight fixtures
• Confirm the fixture and any dimmer are rated for use with this lamp before installation
• Allow the lamp to cool before handling if recently in use
