MISDOOD R7S J118mm T3 Halogen Light Bulbs (6 Pack)
MISDOOD offers a six-pack of 500W R7S J118mm double-ended halogen bulbs designed for 120V fixtures. Measuring 0.39 inches in diameter and 4.6 inches long, these bulbs fit standard T3 halogen fixtures. They emit about 22,500 lumens with a warm 2700K glow and a 360-degree beam for comprehensive coverage. Dimmable and free from lead and mercury, they promise reduced eye strain and no UV or IR radiation, making them suitable for workshops, security lighting, and landscape accents.
TAIYALOO R7S LED Bulb 118mm 100W Equivalent (2 Pack)
TAIYALOO’s LED variant delivers efficiency without sacrificing brightness. At 10W, it can produce around 1000 lumens, closely replacing a 100W halogen while cutting energy use. It’s dimmable on compatible fixtures and aims for smooth performance with minimal flicker or noise. The bulb features a 360-degree beam and a warm white output around 3000K, making it a solid choice for workspaces and exterior lighting that requires consistent illumination with energy savings.
CTKcom 500-Watt 4.7-Inch J Type T3 Halogen Bulbs (5 Pack)
CTKcom’s pack of five J-type T3 halogen bulbs provides a straightforward, high-brightness replacement at 120V and 500W. With a length of 4.71 inches (118mm) and a standard R7S base, these bulbs are designed for reliability in flood lights, work lamps, and security fixtures. They’re described as long-lasting (approx. 2,000 hours) and suitable for fixtures that require strong, immediate illumination, aligning with traditional, bright lighting applications.
Geminilite R7s LED Bulb 118mm 14W (2 Pack)
Geminilite offers a compact LED alternative that fits standard R7S fixtures. At 14W and 1500 lumens, it provides robust brightness with a 360-degree beam.

Buying Guide: Key Considerations For 500W-Equivalent T3 Bulbs
- Light source type: Halogen vs. LED. Halogen bulbs offer immediate full brightness and familiar color temperatures, while LEDs provide energy savings and longer life but may require compatible dimmers or drivers. Consider whether dimmability is a priority for your space.
- Beam angle and brightness: Look for 360-degree coverage and lumen output. For security and landscape lighting, high lumens (thousands) help illuminate wide areas; for task lighting, ensure even distribution to reduce shadows.
- Color temperature: 2700K provides warm, cozy tones; 3000K is a comfortable white; cooler temperatures around 4000K-6000K suit workspaces and highlight details. Choose based on the intended ambiance and color accuracy requirements.
- Base compatibility: R7S double-ended (J118mm) is a common standard for 4.7-inch linear halogen bulbs. Measure fixture requirements to avoid incompatibility and ensure a secure fit.
- Dimming compatibility: If you plan to use dimmers, verify that the bulb is listed as dimmable and that the dimmer is compatible with the bulb type (LED vs. halogen).
- Energy efficiency and lifecycle: LED variants typically offer lower power consumption and longer lifespans; halogens deliver full brightness instantly but consume more energy and have shorter lifespans, impacting total cost of ownership.
- Environmental impact: LED options generally have fewer hazardous materials and reduced UV/IR output, potentially safer for sensitive surfaces and environments.
- Installation considerations: Double-ended bulbs require fixture hardware that supports this configuration. Verify fixture length, diameter, and mounting constraints before purchasing.
- Warranty and availability: Look for products with reliable supplier warranties and consistent availability to avoid frequent replacements.
- Use-case alignment: For workshops and security lighting, prioritize high brightness and robust construction. For ambient or landscape lighting, choose warmer tones and better dimmability if needed.
