SUNPACK T5 LED Conversion Lamp - 36in

Mercury-Free Drop-In LED Upgrade for T5HO Fixtures, 36in

Replacing an entire T5HO fixture just to move from fluorescent to LED is more cost and disruption than most growers need to take on. The Sunpack T5 LED Conversion Lamp is a direct drop-in swap for the tube already in a T5HO bi-pin fixture, delivering LED efficiency and a mercury-free build in the same physical format the fixture was built for.

The 36in length matches standard 36in T5HO fixtures, and installation requirements depend on the fixture's ballast -- some conversion lamps run on the existing ballast, while others need a ballast bypass, so check the lamp's included instructions before installing.

Key Features & Benefits

• Zero-mercury LED formula — removes the mercury that a standard T5HO fluorescent tube contains and needs special disposal for.
• Direct T5HO fixture fit — installs in the corresponding fixture length without rewiring or an adapter, aside from any needed ballast bypass.
• More stable output over time — holds its lumen output more consistently across its life than a fluorescent tube, which dims from its first hours of use.
• LED efficiency and lifespan — trades the shorter service life and annual replacement of a T5HO tube for a longer-lived LED source.

Who Should Use This

Growers with an existing T5HO fixture who want the benefits of LED -- longer service life, mercury-free disposal, and more consistent output -- without replacing the fixture itself are the right fit for this conversion lamp.

About Sunpack

Sunpack sells this conversion lamp as an alternative to its standard replacement T5HO tube, aimed at growers ready to move an existing fixture from fluorescent to LED.

Frequently Asked Questions

Do I need to rewire my fixture to use this lamp?

It depends on the fixture's ballast. Some T5 LED conversion lamps run on the existing ballast as installed, while others require a simple ballast bypass, so always follow the specific instructions included with the lamp before installing.

How does the light output compare with the fluorescent tube it replaces?

LED conversion lamps typically match or exceed the initial output of the T5HO fluorescent tube being replaced, while drawing less power. LED output is also more stable over time than fluorescent, which dims from its first hours of use rather than holding steady.

Why does removing mercury from the fixture matter?

Fluorescent tubes contain mercury, which creates a disposal concern since broken tubes release mercury vapor and used tubes need specialist recycling rather than standard trash disposal. A mercury-free LED conversion lamp removes that concern from routine lamp replacement.

Will this lamp work in any brand of T5HO fixture?

Yes, it is built for standard T5HO bi-pin fixtures generally, not limited to Sunpack fixtures. Confirm the tube length and ballast compatibility of your specific fixture before ordering.
