## Overview

The AgroMax 4 Foot UV-A + 10,000K T5 Fluorescent Grow Light Bulb is a 54-watt high-output T5HO lamp engineered specifically for horticultural use. It combines a finely tuned UV-A and cool white 10,000K spectrum to promote vigorous flowering and plant health. Compatible with 4' T5HO fixtures featuring a mini bi-pin (G5) base, this bulb offers an extended lifespan of over 20,000 hours, ensuring long-term, energy-efficient supplemental lighting for indoor gardening enthusiasts and professionals alike.

## Description

AgroMax high-output T5 (T5HO) bulbs produce 2x the light output of standard T5 lamps. Unlike rebranded general-purpose lamps offered by others, AgroMax T5 bulbs have been engineered specifically to provide optimized plant growth. With the most finely tuned spectral formulas for horticultural use and more growing power, AgroMax T5HO bulbs offer superior performance. SPECTRUM: The AgroMax UV-A Plus bulb is a specialty supplemental T5HO designed to encourage natural flowering development with ultraviolet light. It is intended to be used in conjunction with a primary light source such as flowering T5HO lights or HPS grow lights. AgroMax 4' F54T5HO bulbs are compatible with 4' T5HO fixtures only. Please confirm your fixture's compatibility before ordering as fluorescent lights come in numerous sizes, each requiring a specific bulb wattage and size.

Review: clever packaging - I debated ordering fragile flourescent bulbs, but did so half out of interest in seeing how they were shipped. The clever use of triangular packaging ensures that the fragile glass remains well protected. The bulbs are fine, but the minimal use of cardboard to achieve a stiff, sturdy container is what prompted this review :-)
Review: My plants really like these bulbs - I replaced the bulbs in one of the fixtures in my garage with these bulbs. This fixture provides light for my large potted outdoor plants when I bring them in for the winter. My plants have never looked better. My orange tree is blooming like crazy and the garage smells like orange blossoms. I’ve had this tree for years and I’ve never seem more than a couple of blooms in all those years. I’ll be replacing bulbs in more fixtures with these next year.

### ⭐ Not as bright
*by R***N on November 23, 2022*

They say 10,000k is what the bulbs is, that a joke I have 10000 that I use for my current fish tank I tan my Arowan but this light bulb look like a 60watt bulb
