CTKcom 500W Halogen Bulbs (5 Pack) — R7S 118mm Double Ended
Best for budget installations and fixtures designed for R7S double-ended halogen bulbs. These CTKcom bulbs are 118mm long with a 500W rating and operate at 120V. The pack includes five bulbs, offering a cost-effective option when multiple replacements are needed at once. Best used in fixtures with traditional halogen sockets where LED equivalents are not yet installed, or where fixture compatibility is strictly R7S 118mm.
Best for: buyers who need multiple replacements at a fixed price and that do not require LED performance claims. Choose this if your fixture is designed for halogen form factors and you want a simple, budget-friendly swap. Caution: These are halogen bulbs, not LED, so energy savings will be limited compared to LED options; verify fixture compatibility with 110–130V supply before purchasing.
Lustaled 500W LED R7S 118mm (4.7”) — Bright 8000 lm
Best for high brightness needs in workshops, security floodlights, and landscape lighting. This Lustaled LED replaces 500W halogen with around 8000 lumens, using a 118mm R7S double-ended design. It supports dimming to adjust mood and energy use. It is well suited for fixtures that accommodate R7S 118mm bases and can benefit from significant energy savings compared with 500W halogen.
Best for: users seeking maximum brightness with LED efficiency in standard R7S fixtures. Limitation: ensure your dimmer is compatible with LED R7S bulbs, and confirm that your fixture size allows the 118mm length for safe operation.
Luxvista R7S LED Bulb 30W — 118mm, Dimmable
Best for energy savings and dimming control in ceiling light fixtures and floor lamps. This Luxvista 30W LED R7S bulb provides a 118mm length and dimmable capability with a warm 5000K daylight tone. It replaces a 500W halogen in compatible fixtures, delivering instant full brightness with high color rendering. Advantage: substantial energy reduction with smooth dimming for task lighting or ambiance.
Caution: verify dimmer compatibility and confirm the fixture accepts a 118mm double-ended R7S LED before purchase. Best for fixtures that are designed for LED R7S replacements and dimmable operation.
QLEE R7S LED Bulb 50W — Warm White, 3000K
Best for warm ambient lighting in indoor spaces where a 500W halogen replacement is desired but in a smaller LED form. The QLEE 50W LED uses a 118mm J-Type R7S base and is advertised as dimmable with a warm 3000K tone. It provides a solid lumen output while maintaining lower energy consumption compared with halogen bulbs.
Better for: fixtures needing warm, soft white light with dimming capability. Limitation: check the size and ensure your fixture is compatible with the J-Type 118mm LED length and dimmer requirements.
TAIYALOO R7S 500W 118mm Halogen Replacement (5 Pack)
Best for multi-bulb replacement in larger spaces or fixtures requiring robust, high-output LED replacements. These R7S LEDs deliver about 7500 lumens equivalence with a 2700K warm white tone and are dimmable on many fixtures. The 118mm length fits standard R7S sockets, making them a practical option for general use in work areas and security lighting applications.
Choose this if you want a longer-lasting LED option with easy replacement in multi-bulb setups. Caution: confirm dimmer compatibility and verify that 2700K warm white matches your lighting needs for the space.
Buying Guide
- Base and size compatibility: Most incandescent-to-LED replacements use R7S double-ended bases of 118mm (4.7″) length. Larger lengths like 189mm (Rowrun J189) require fixtures that accommodate longer bulbs. Ensure your fixture’s socket, housing, and reflector support the bulb length.
- Brightness and equivalence: LED replacements often list lumen output and an equivalence to a 500W halogen. Look for around 4700–8000 lm for a strong floor, task, or outdoor floodlight replacement, depending on distance and beam angle.
- Color temperature: Warm white (2700K–3000K) creates cozy spaces; daylight (5000K–6500K) suits task lighting and work areas. Consider CRI (color rendering index) 85+ for true-to-life colors in displays or retail.
- Dimming: If you need dimming, verify compatibility with your fixture’s dimmer and LED technology. Not all LED R7S bulbs are dimmable or work with every dimmer type.
- Heat and longevity: Aluminium bodies and built-in heat dissipation help extend LED life. Compare lifespans and wattage to estimate long-term savings versus halogen.
- Application context: For outdoor or security lighting, higher brightness and longer bulb length may be advantageous; for indoor lamps, smaller sizes and warm tones may be preferred.
FAQ
- Will these LEDs fit my existing halogen fixtures? Most LED replacements use the same R7S double-ended base; check bulb length and fixture socket compatibility before purchasing.
- Is 30W LED equivalent to 500W halogen? LED wattage is not directly equivalent; look at lumen output. A 30W LED R7S can equal roughly 4700–8000 lumens, offering substantial brightness with far lower power draw.
- Can I use LED R7S bulbs with a dimmer? Some are dimmable, but you must confirm dimmer compatibility with the specific LED model and fixture. Non-dimmable models will not work properly with dimmers.
- What is the best choice for energy savings? LED replacements generally save the most energy, especially when replacing 500W halogen with 30–50W LEDs while maintaining similar brightness.
- Are there safety or disposal considerations? LEDs are free of mercury, unlike some halogen or fluorescent tubes; dispose according to local electronics recycling guidelines.
