R7S LED Bulb 78MM 15W Dimmable J78 Flood Light - Cool White

In this review the R7S LED Bulb 78MM by Familite is evaluated as a direct LED replacement for common 78mm halogen linear lamps used in torchiere floor lamps, wall sconces and work lights; the single biggest reason to consider it is energy savings combined with dimmable performance. The bulbs deliver about 1500 lm at 15W in a cool white 6000K color, and the review focuses on fit, brightness, dimming behavior and durability after customers swapped them into fixtures that originally used 150W halogen T3 lamps.

Key Features

• Exact size: Measures 78mm length by 30mm diameter so buyers can verify fit before ordering to avoid incompatibility in tight fixtures.
• High output: Rated 15W and about 1500 lm, replacing roughly 150W halogen floods while using far less power for noticeable energy savings.
• Dimmable performance: Works across a 10%-100% dimming range and provides smooth dimming with no apparent flicker when paired with compatible controls.
• Durable construction: Uses a ceramic R7S base and an aluminum plate with a plastic housing that runs cooler and is less fragile than glass tube replacements.
• Direct replacement design: Built to replace 78mm tungsten halogen linear lamps found in torchieres, banker lights, chandeliers and outdoor flood fixtures.

Who It's For

The R7S 78MM LED is best for homeowners and small commercial users who need a high-output LED to replace 150W halogen T3 bulbs in floor lamps, wall sconces, work lights and some outdoor flood fixtures and who value dimming capability and energy savings. It suits anyone who can confirm the fixture accepts a 78mm by 30mm double-ended lamp and wants a cool white 6000K output for task or security lighting.

Those who should look elsewhere include shoppers who require a warmer color temperature for living spaces or those who prioritize the longest possible lifetime above initial cost; a few customers reported premature failures, so buyers needing mission-critical, maintenance-free lighting might select a bulb model with longer field-proven longevity.

Pros & Cons

Pros

• Bright 1500 lm output at 15W gives a clear energy-efficiency advantage over 150W halogen equivalents.
• Smooth dimming from 10% to 100% without noticeable flicker on compatible dimmers.
• Sturdier ceramic base and aluminum plate reduce heat and fragility compared with glass tube designs.
• Good fit and replacement value for a wide range of fixtures when measurements match.

Cons

• Some users reported mixed lifespan performance, with a few units failing sooner than expected.
• The bulb is slightly thicker than some J-type halogens, so precise measurement of fixture clearance is required.
