Hydroponic Seed-Starting Bulb

The Miracle LED 602126 is a 12 W blue-spectrum LED grow bulb designed for indoor seed starting and early vegetative growth. It fits standard E26 sockets and operates on a plug-and-play basis without external ballasts. The frosted A21 housing is shatter-resistant and rated for enclosed fixtures, making it practical for hobby tents or kitchen-counter setups.

450 nm Peak Wavelength

The single specification that determines suitability is the 450 nm peak wavelength, which targets the blue region that drives compact, stocky seedling development. A 180-degree beam angle spreads light evenly across trays, while the 150 W incandescent equivalency indicates the photon output level you can expect from a 12 W draw.

Shatter-Resistant Frosted Housing

The plastic frosted diffuser softens the spot-style distribution, reducing hot spots on delicate cotyledons and protecting the diodes from accidental impact. Rated to start at -4 °F, the bulb remains reliable in unheated garages or basements. A one-year manufacturer warranty covers premature failure under normal indoor use.

Questions about this item

How does the 150 W incandescent equivalency translate to actual power draw in a real fixture?

The bulb draws 12 W while delivering light output comparable to a 150 W incandescent, so it uses far less electricity for the same growing intensity.

What does the 450 nm peak wavelength mean for the light spectrum my plants receive?

The 450 nm peak sits in the blue region that drives vegetative growth and seed starting, giving a targeted spectrum rather than a broad white output.

Will the A21 shape and 180 degree beam angle fit and cover properly in my existing hood?

The A21 envelope fits standard E26 sockets and the 180 degree spread directs light downward, so it works in most grow hoods without extra reflectors.
