Buying Guide
What matters most when choosing T3 100W halogen bulbs?
- Base and size: Ensure R7S/J78mm compatibility for your fixture. Measure length (about 3.07 inches) and diameter (about 0.39 inches).
- Brightness and color: 2700K warm white is common; check lumen output to match your lighting needs (roughly 800–4500 lm range across options).
- Voltage and stability: Most options run at 120V; look for flicker-free, stable output to avoid frequent replacements.
- Dimmability: If you use dimmers, confirm the bulb is dimmable and compatible with your dimmer type.
- Eco concerns: Many are lead- and mercury-free with no UV/IR radiation; this is better for both environments and eye comfort.
- Lifetime and maintenance: Expect typical lifespans around 2000 hours; plan for replacements in bulk where appropriate.
