Two-Pack Red Blue Spectrum Grow Bulbs

This two-pack delivers 11 W LED grow bulbs that replace 150 W incandescent equivalents. The red and blue spectrum targets flowering, fruiting, high-yield production and vegetative growth. Shatter-resistant plastic housing with a frosted finish suits indoor growing setups. Each A21 bulb operates from a standard plug-and-play base.

270-Degree Beam Angle Coverage

A wide 270-degree beam angle spreads light across a broader canopy than narrow optics. The peak wavelength at 630 nm sits in the red region that drives flowering and fruiting response. Frosted finish diffuses output for more even plant exposure. Shatter-resistant construction reduces breakage risk during handling.

Enclosed Fixture and Temperature Limits

These bulbs are not rated for enclosed fixtures, so heat buildup in sealed housings will shorten life. Minimum starting temperature is -4 °F, allowing use in unheated spaces during cold months. One-year manufacturer warranty covers early failures. Plastic housing and LED technology keep surface temperatures lower than incandescent grow lamps.

Questions about this item

How often will the 11W LED grow bulbs need replacing?

The manufacturer backs the 602153 bulbs with a 1-year warranty; LED diodes typically last many times longer than that under normal grow cycles.

What limits continuous daily operation of the 602153 bulbs?

They are rated for open fixtures only and must not be used in enclosed housings, so heat buildup in a closed canopy is the first practical limit.

How much heat and noise do the 11W bulbs produce when run all day?

LED technology runs silently; the frosted A21 housing stays warm but well below the 150W incandescent equivalent it replaces.
