SunBlaster T5HO 2700K Replacement Lamp, 48"

T5HO 2700K Replacement Lamp, 48 Inch

T5HO lamps lose output gradually over their lifespan long before they burn out completely, and a flowering room running on a dimmed lamp can lose spectrum quality without an obvious sign. This lamp is a direct swap-in replacement at a 2700K spectrum, built to restore warm-spectrum output to a compatible T5HO fixture.

The 2700K spectrum leans toward the warmer end of the color range, suited to flowering and fruiting stages of indoor plant growth, and replacing this lamp after roughly 10,000 hours of use helps maintain consistent output.

Key Features & Benefits

• 2700K spectrum — leans warm, suiting the lamp to flowering and fruiting stages.
• 48-inch length, 54W draw — drops directly into 48-inch T5HO fixtures without modification.
• SunBlaster factory-spec lamp — matches the tube dimensions and electrical draw of the lamp originally shipped with the fixture.
• Drop-in fixture replacement — seats in the existing T5HO socket with no rewiring or extra hardware.

Who Should Use This Replacement Lamp

Growers with a 48-inch T5HO fixture whose lamp has dimmed or burned out and needs a warm-spectrum replacement for flowering or fruiting are the best fit for this lamp.

Frequently Asked Questions

What spectrum does this lamp produce?

A 2700K spectrum, sitting at the warmer, redder end of the color range. That spectrum suits flowering and fruiting stages rather than vegetative growth.

What length fixture does it fit?

48-inch T5HO fixtures, drawing 54 watts. It seats into that exact fixture length rather than acting as 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 flowering-stage spectrum consistent.

Is this a direct swap-in replacement?

Yes — it seats directly into an existing 48-inch T5HO socket with no rewiring required. The lamp ships ready to install without adaptors or other extra hardware.
