SunBlaster T5HO 6400K Replacement Lamp, 36"

T5HO 6400K Replacement Lamp, 36 Inch

T5HO lamps lose output gradually over their lifespan long before they burn out completely, so a fixture can be running dimmer than it should without an obvious sign. This lamp is a direct swap-in replacement at a 6400K spectrum, built to restore full-spectrum output to a compatible T5HO fixture.

The 6400K spectrum leans toward the cooler, bluer end of the color range, suited to vegetative growth and propagation stages, and replacing this lamp after roughly 10,000 hours of use helps maintain consistent output.

Key Features & Benefits

• 6400K spectrum — leans cool, suiting the lamp to vegetative growth and propagation stages.
• 36-inch length — drops directly into 36-inch T5HO fixtures without modification.
• Genuine SunBlaster lamp — manufactured to SunBlaster's own fixture specifications.
• Easy swap-in replacement — installs into the existing T5HO socket without rewiring the fixture.

Who Should Use This Replacement Lamp

Growers with a 36-inch T5HO fixture whose lamp has dimmed or burned out and needs a cool-spectrum replacement are the best fit for this lamp.

Frequently Asked Questions

What spectrum does this lamp produce?

A 6400K spectrum, which leans toward the cooler, bluer end of the color range. That spectrum suits vegetative growth and propagation stages rather than flowering.

What length fixture does it fit?

36-inch T5HO fixtures. It's built as a direct swap-in for that fixture length rather than a universal-fit lamp.

How often should it be replaced?

Roughly every 10,000 hours of operation. T5HO lamps lose output gradually over that span even before they fully burn out, so replacing on that interval keeps output consistent.

Is this a direct swap-in replacement?

Yes, it drops into an existing 36-inch T5HO socket without rewiring the fixture. No adaptors or additional hardware are needed to complete the swap.
