Rowrun R7S LED bulb 118 mm

Replacing a double-ended halogen bulb can mean choosing between familiar output and lower wattage. This R7S LED is listed at 15 W and 1,500 lm, with a natural-white 4000 K colour temperature.

Its 118 mm length and 20 mm diameter make fit an important first check. Measure the existing bulb and compare it with your fixture before choosing.

If you prioritize lower stated wattage, this format may suit your setup, if you prefer a bulb with broadly listed voltage and dimmer details, the information here leaves some questions to settle first.

Where it shines

This bulb is intended as a replacement for a double-ended T3 halogen bulb. The listed 1,500 lumens and 360° beam angle point to broad, all-around illumination rather than a narrow directional beam. That can be useful in a compatible fixture where light needs to spread around a room or work area. For example, when switching on a fitting in the evening, the LED is described as reaching full brightness instantly, so there is no stated warm-up period.

The 4000 K output is natural white, a middle-ground choice if you want a less warm look than many halogen bulbs provide without moving to a cooler, bluer white. A CRI of at least 80 is also listed, which may matter where you want everyday colours to look reasonably natural. Those figures describe the product’s stated output, they do not establish how it will look in every fixture or space.

Quick overview

Rowrun lists this as a dimmable R7S LED with 156 2835 SMD LEDs, an AC 110 V rating and a ceramic body with a PC cover. The pack contains two bulbs. Its stated 15 W consumption is presented as equivalent to a 150 W double-ended T3 halogen bulb, and the manufacturer claims a 5,000-hour lifespan. Treat those as product specifications, not a guarantee of identical brightness or lifetime in every installation.

The main limitation is compatibility information. The listing gives the bulb’s size and voltage, but does not identify specific fixture or dimmer models. Since it is described as dimmable, confirm that your fitting and dimmer support this LED type before relying on dimming. It also lists AC 110 V, so check the voltage requirements for your fixture rather than assuming it will suit every installation.

Best use cases

It makes sense if you have a double-ended R7S fitting, want a 118 mm bulb, and are looking to replace a halogen lamp with a lower-wattage LED. The two-bulb pack is practical when you need to replace a pair or keep a matching spare. The listed ceramic and PC construction, along with claims of no flicker or noise, may also appeal for regular indoor use, though no specific room or fixture suitability is provided.

Best to avoid it if you have not confirmed the socket format, bulb dimensions and AC 110 V requirement, or if you need certainty about dimmer compatibility before purchasing. A standard replacement chosen for a known fitting may be the simpler route when those details are uncertain, this LED makes more sense when its R7S format and measurements match what you already use.

Final thoughts

This Rowrun bulb is a targeted replacement, not a universal LED: its appeal rests on the R7S format, 118 mm length, 4000 K light and stated 1,500 lm output. According to the manufacturer, it is dimmable and rated for 5,000 hours, but the available details do not name compatible dimmers. Choose it when your fitting matches the listed dimensions and voltage and you want the stated halogen-equivalent output at 15 W. If either the electrical requirement or the fit is uncertain, confirm those details first or choose a bulb with specifications that clearly match your fixture.
