Grow Bulb 11W Blue Spectrum 4-Pack

Miracle LED 602150 is an A19 LED grow bulb sold in a four-pack. Each unit draws 11 watts while matching the output of a 150 watt incandescent. The blue spectrum peaks at 450 nanometres to support seed starting and early vegetative growth. A frosted plastic housing provides omnidirectional light with a 270 degree beam angle.

Best for Seed Starting Not for Flowering

These bulbs suit indoor gardeners who need a plug-and-play blue spectrum for germination and young plants. The shatter-resistant housing and -4 °F minimum starting temperature allow use in unheated spaces. Growers who require red or full-spectrum output for flowering and fruiting stages should choose a different spectrum. Enclosed fixtures are not supported.

Peak Wavelength 450 nm Decides Fit

The single specification that determines compatibility is the 450 nanometre peak wavelength. This blue output drives chlorophyll absorption for seedlings and leafy greens. If your crop plan demands red or far-red wavelengths for bloom induction, this bulb will not meet that requirement. Check your plant lighting recipe before purchasing.

Questions about this item

Will the A19 bulb fit my existing lamp holder?

The bulb uses an A19 shape with a standard medium base, so it fits common household sockets.

Do I need any wiring or tools to start using these bulbs?

They are plug-and-play LED bulbs; simply screw each one into a compatible socket and switch on.

How long before the blue-spectrum output drops enough to replace them?

The manufacturer warrants the bulbs for 1 year, after which light output may gradually decline.
