Miracle LED 602128 12W A21 LED Grow Bulb Red Blue Spectrum

Miracle LED 602128 12W Grow Bulb

The Miracle LED 602128 is a 12 watt A21 LED grow bulb that delivers a red and blue spectrum for indoor plant lighting. It replaces a 150 watt incandescent equivalent while drawing only 12 watts of power. The frosted, shatter-resistant plastic housing produces a 180 degree beam angle for wide coverage.

Ideal for flowering and vegetative growth

This bulb suits growers who want a single lamp for flowering, fruiting, high-yield production and vegetative growth stages. The peak output at 630 nanometres targets photosynthesis directly. Buyers who need a different spectrum, higher intensity or a non-standard base should look at other options.

Red and blue spectrum with 630 nm peak

The decisive specification is the red and blue spectrum with a peak wavelength of 630 nanometres, which drives chlorophyll absorption for flowering and fruiting. If your plants require a broader white spectrum or specific far-red output, this bulb will not match that requirement.
