Buying Guide
- Color temperature: Choose 5000K–6000K for daylight-like brightness. 5000K tends toward a slightly warmer daylight, while 6000K is closer to noon sun.
- Color Rendering Index (CRI): Aim for 90 or higher for natural color reproduction, especially in spaces used for reading, crafting, or color-critical tasks.
- Flicker and eye comfort: Look for flicker-free designs to reduce eye strain during extended use. If dimming is needed, ensure compatibility with your fixtures.
- Lumens and brightness: Higher lumens provide brighter light; match lumen output to room size and fixture type, keeping energy efficiency in mind.
- Energy efficiency and lifespan: Longer lifespans lower replacement frequency and total cost of ownership.
- Pack size and compatibility: Consider multi-pack options for larger rooms or multiple fixtures, and verify base (E26/E27) compatibility with existing sockets.
- Special features: Some bulbs offer enhanced circadian benefits, plant-friendly spectra, or enhanced TM-30 metrics—assess needs for mood, productivity, or plant growth.
- Application perspective: For offices or study areas, higher CRI and consistent brightness support concentration; for living rooms, a balanced, non-dazzling light can improve comfort.
- Cost vs. value: Compare upfront cost against long-term energy savings and bulb lifespan to determine best value over time.
