R7S LED Bulb 78MM 15W Dimmable J78 Flood Light - 150W Halogen

In this review the R7S LED Bulb 78MM 15W is evaluated for people replacing linear halogen lamps in torchiere floor lamps, wall sconces, work lights and banker lights. The bottom line: this pack of four offers a clear, energy-saving swap for 150W halogen fixtures with smooth dimming and a compact 78mm length, but buyers must check fixture clearance because the bulb is wider than some J-type halogens. If you want lower power draw, good lumen output and a durable ceramic base, this R7S LED is worth considering.

Key Features

• Size and fit: A direct replacement designed to match fixtures that accept a 78mm linear lamp while noting the bulb is 30mm in diameter so clearance should be verified.
• Brightness: Produces about 1500lm at 15W, delivering light comparable to a 150W halogen while using much less energy.
• Dimmable performance: Smooth dimming from roughly 10% to 100% with no noticeable flicker on compatible dimmers for adjustable ambiance and task lighting.
• Durable construction: Ceramic R7S base with an aluminum plate and plastic housing that runs cooler and is less fragile than glass tube designs.
• Application versatility: Sized and shaped to work in torchieres, work lights, security lights, chandeliers and wall sconces that accept 78mm linear bulbs.
• Warranty: Includes a 12-month free replacement warranty for basic assurance against early failures.

Who It's For

This bulb is best for homeowners and workshop users who want to replace older 150W halogen R7S lamps with a lower-power LED that still delivers strong lumen output and dimming. It suits people who need a compact linear bulb for floor torchieres, banker lamps and certain wall sconces, provided their fixture accepts a slightly larger diameter than some J-type halogens.

It is not ideal for users who cannot verify fixture internal clearance or who require an exact match to a slimmer J-type tube, since this model is 30mm wide and described as fatter than some double-ended halogen bulbs. Also, longevity reports are mixed so those seeking long-term industrial duty may want to monitor early performance.

Pros & Cons

Pros

• High effective output: about 1500lm from 15W replaces a 150W halogen on light output while saving energy.
• Smooth dimming: performs across a wide dimming range without obvious flicker on compatible dimmers.
• Durable base: ceramic R7S base and aluminum plate reduce fragility and heat compared with glass tube bulbs.
• Good replacement value: sold in a pack of four, useful for multi-lamp fixtures or whole-room swaps.

Cons

• Mixed longevity: some customers report early failures, so lifespan may vary in practice.
• Bulb diameter: at 30mm it is wider than some J-type halogen tubes and may not fit every fixture without checking clearance.

Our Verdict

The R7S LED 78mm 15W is a practical, energy-efficient replacement for 150W halogen linear lamps for anyone who confirms fixture clearance and wants smooth dimming plus a robust ceramic base.
