Double Ended R7s

5 products

Double ended R7s LED bulbs are the modern, energy-efficient replacement for the linear halogen tubes used in floor lamps, security floodlights, and workshop lighting. Where a traditional halogen bulb wastes most of its energy as intense heat, an R7s LED provides comparable brightness for about 10-15% of the power consumption. SuperLightingLED provides a complete range of R7s LED replacements in the two standard lengths, 78mm and 118mm, designed to retrofit directly into your existing J-type fixtures.

Upgrading is straightforward. You get instant-on brightness without the warm-up time of old bulbs, and a much longer service life, with some models rated for 40,000 hours. The significantly cooler operating temperature also reduces the risk of heat damage to fixtures and nearby surfaces. Our R7s bulbs are designed for wide voltage compatibility, with most models operating on AC 100-240V, making them suitable for installations across different regions.

What is an R7s LED Bulb?

An R7s LED bulb is a direct replacement for a linear halogen lamp, designed to fit the same double-ended, recessed single contact (RSC) base, often called a J-type fixture. The primary job of these bulbs is to deliver the high light output of a halogen without the extreme power draw and heat. We list models that replace halogens from 70W all the way up to 200W.

R7s LED Bulbs: Physical Fit and Dimming Compatibility

Successfully retrofitting an R7s halogen bulb with an LED requires checking more than just the length. The most common issues installers face are the physical size of the new bulb and its compatibility with existing dimmer switches. Our product line is designed with clear specifications to help you get the right fit the first time.

Will This R7s LED Fit My Fixture? Check Diameter First.

The single most important check is physical clearance. An R7s LED bulb is significantly thicker than the pencil-thin halogen tube it replaces to make room for the LED drivers and heat sinks. Many torchiere lamps or enclosed floodlights have tight housings. Before you order, measure the inside of your fixture. Always compare these dimensions against your available space.

Dimmable vs. Non-Dimmable R7s Models

We offer both dimmable and non-dimmable R7s bulbs because not all fixtures need this function. Our dimmable models (3 of the 5 in our range) are designed to work with modern LED-compatible TRIAC dimmers. If you connect them to an older dimmer designed for the high-wattage load of a halogen bulb, you might experience flickering, a reduced dimming range, or buzzing. For the best results, pair dimmable R7s LEDs with a modern dimmer. If your fixture is a simple on/off switch, a non-dimmable bulb is a more cost-effective and reliable choice.

Common Applications

The high output of these LED light bulbs makes them a solid choice for specific tasks. You'll typically find them in:

  • Torchiere Floor Lamps: The bright, indirect light is perfect for illuminating an entire room.
  • Security and Landscape Floodlights: The instant-on, high-lumen output effectively lights up outdoor areas.
  • Workshop and Garage Lights: Provides powerful, widespread task lighting over workbenches.
  • Architectural Wall Sconces: Used for wall-washing effects and accent lighting.

For any of these uses, converting to LED not only saves on your power bill but also dramatically reduces how often you need to get a ladder out to change a burned-out bulb. 

Frequently Asked Questions About Double Ended R7s LED Bulbs

Got a question about swapping out your old halogen R7s tubes? I've answered thousands of these over the years. Here are the most common ones.

It's the physical length, and you have to match it exactly. An 118mm double ended R7s LED bulb simply will not fit in a 78mm fixture, and vice-versa. This is the most common mistake people make. Measure the glass part of your old halogen bulb from tip to tip before you order.

Usually, no. Our double ended R7s LED bulbs are designed as direct, drop-in replacements for halogen tubes. You just pop the old one out and put the new one in. They run on the same AC mains voltage your fixture already provides. No complex wiring diagram is needed for a standard swap.

The LED equivalent of a 100 watt halogen is a bulb that uses about 10 to 15 watts. But don't just shop by watts. The real measure of brightness is lumens. A 100W halogen is about 1200-1600 lumens, so you'll want to match that number. For instance, our 15W dimmable 118mm R7s produces 1300 lumens, making it a great 130W equivalent.

Not even close. A halogen R7s can hit over 500°F (260°C) — a serious burn risk. Our R7s LED replacements run dramatically cooler. You can often touch them briefly without injury, though I'd still be cautious. This massive heat reduction is a huge safety benefit, especially for indoor uplighters accessible to kids or pets.

Nope, it's non-polarized. A double ended R7s LED bulb gets AC power from the contacts at both ends, so you can install it either way around in the socket. Unlike some low-voltage DC products, there's no positive or negative to worry about. It just clips right in.

Absolutely, that's one of their most popular uses. The bulb itself isn't waterproof, but it doesn't need to be because the security light housing provides the weather protection. As long as your fixture is rated for outdoor use (e.g., IP65), our R7s bulbs will work perfectly inside it. Their instant-on performance is a huge upgrade for motion-activated lights.

A 150-watt R7s halogen bulb produces around 2000-2400 lumens. To get an equivalent brightness, you need to match that lumen count. Our 30-watt 118mm R7s LED replacement, for example, puts out up to 3000 lumens, making it powerful enough to replace even a 200W halogen bulb. Always compare lumens, not just watts.

It just means the bulb gets power from contact points at both ends. It clips into the fixture between two sockets, unlike a standard single color LED bulb which screws into a single base. The 'R7s' part specifies the type of recessed contact at each end. It's a simple, robust design made for linear tube-shaped bulbs.
