How it works
The Finally Light Bulb uses electromagnetism to "induce" an electric field within the bulb. This electric field interacts with various gases, which in turn will glow and emit light.
Mercury
Those gases include a trace amount of mercury, same as CFL bulbs. If you break one like we accidentally did, you'll need to be somewhat careful cleaning it up.
Good-looking skin
Like an incandescent, the Finally Light Bulb offers light quality that's complementary to skin tones of all shades.
Spectral graphs
Graph out its light output across the visible light spectrum, and the Finally Light Bulb most closely resembles a CFL.
No dimmability
The Finally Light Bulb isn't dimmable. Try and dim it on a dimmer switch anyway, and it'll flicker badly.
Color quality
Overall, the Finally Light Bulb offers below-average color-rendering capabilities.
Price point
The Finally Light Bulb sells online for $10, plus shipping. Is it worth the premium? Check out our review for the verdict.
