Miracle LED 12W A21 Grow Bulb

This Miracle LED 602130 is a 12 watt LED grow bulb with an A21 shape and a frosted, shatter-resistant plastic housing. It delivers a red and blue spectrum peaked at 630 nanometres and a 180 degree beam angle for broad canopy coverage. The bulb is rated as a 150 watt incandescent equivalent and plugs directly into standard sockets.

Suited for indoor flowering.

Growers targeting high-yield production in hydroponic or soil setups will benefit from the tailored spectrum and enclosed-fixture rating. The bulb starts at minus four degrees Fahrenheit, so unheated spaces are viable. It is not intended for general room lighting or for growers who need a full-spectrum white output for visual inspection.

Steady output in enclosed fixtures over long cycles

The plastic housing and enclosed-fixture rating allow continuous operation without the overheating that shortens lesser bulbs. Light output remains stable across extended photoperiods required for flowering and fruiting stages. The one-year manufacturer warranty covers defects during sustained use.

Questions about this item

Does this A21 grow bulb fit a standard household lamp holder?

The bulb shape is A21 and the power source is plug and play, designed for ordinary sockets.

Can I run this 12 W LED alongside older 150 W incandescent grow lights on the same circuit?

Yes, at 12 W it draws far less current than a 150 W incandescent equivalent, so both can share a circuit.

How can I confirm the red-blue spectrum is active after I install the bulb?

The peak wavelength is 630 nm in the red band, and the frosted housing shows a visible magenta glow when operating.
