Miracle LED 602148 11W Blue Spectrum Wide Angle Standard Bulb

Blue spectrum LED grow bulb

The Miracle LED 602148 is an 11 watt A21 bulb that emits a blue spectrum peaked at 450 nm for seed starting. Its 270 degree beam angle and omnidirectional distribution spread light across a wide area. The frosted plastic housing is shatter resistant and the lamp is rated for a minimum starting temperature of minus four degrees Fahrenheit. It replaces a 150 watt incandescent equivalent while drawing only 11 watts.

Plug and play standard base fit

The bulb uses a standard base for direct plug and play installation in compatible sockets. No external ballast or driver is required so it frees up wiring complexity in a grow setup. It is not rated for enclosed fixtures so the surrounding fitting must allow open air circulation. The one year manufacturer warranty covers the lamp itself. Builders needing a different spectrum or higher output for later growth stages will need additional lighting.

Sustained output in open air

Under continuous operation the LED package maintains its spectral peak as long as the fixture provides open ventilation. The plastic housing and lack of enclosed fixture rating mean heat must dissipate freely to avoid premature degradation. Light output remains stable across the 270 degree spread during long photoperiods typical of seed starting. The bulb is not suited for sealed housings or high ambient temperatures beyond the stated minimum start point.
