Technical Specifications

Product Overview

SYLVANIA GRO-LUX Aquarium and GRO-LUX Aquarium Wide Spectrum fluorescent lamps are built for indoor growing rather than for general illumination. Light supplies the energy plants use to produce food and the other substances required for growth and flowering, and these lamps concentrate their output in the parts of the spectrum most useful for germination, propagation and growth, photosynthesis, chlorophyll synthesis, and enhancing vegetation.

The Wide Spectrum version puts more energy into the red portion of the spectrum, which is what high-energy flowering plants need. SYLVANIA positions it for plants requiring full sunlight, and notes that a 50/50 mix of GRO-LUX Aquarium and GRO-LUX Aquarium Wide Spectrum lamps may produce the best results for high-energy plants. Photosynthetically Active Radiation varies according to the cultivar grown, so the right mix is worth testing against the specific planting.

Beyond supplying growth energy, GRO-LUX lamps are intended to bring out the natural colors of foliage, flowers and vegetables, which is why they are common in display planting and aquarium applications as well as propagation. This lamp is a f40 rapid start type and is not a self-ballasted or direct-wire product; it requires a matching fluorescent ballast.

Compatible Applications

• Planted freshwater aquariums and aquascapes
• Indoor gardening, propagation benches, and seed starting
• House plant and foliage display lighting
• Terrariums, vivariums, and paludariums using linear fluorescent hoods
• Greenhouse supplemental lighting during short-day periods
• Retail plant and produce display where natural color rendition matters
• Existing T12 48 in. fixtures with medium bi-pin lampholders and a matching f40 rapid start ballast
• High-energy flowering plants and fruiting crops requiring full-sunlight equivalent
• Paired 50/50 with GRO-LUX Aquarium lamps in multi-lamp fixtures

Before Ordering – Verify

• Confirm the ballast type. This is a f40 rapid start lamp. It will not perform correctly on a ballast intended for a different starting method.
• Confirm the fixture accepts a T12 lamp. T12 is 1.59 in. maximum diameter and T8 is 1.10 in.; the two are not interchangeable in most fixtures even at the same wattage and length.
• Confirm the fixture length. This lamp is 48 in. nominal with a 47.78 in. maximum overall length and 47.50 in. base face to opposite pin.
• Confirm the lampholder is medium bi-pin.
• Confirm you want the Wide Spectrum version. GRO-LUX Aquarium Wide Spectrum is for plants requiring full sunlight; the standard GRO-LUX Aquarium lamp is for plants requiring indirect sunlight, and the two have different spectral output.
• Confirm the packaging. This item ships as retail package.
• For planning coverage, SYLVANIA suggests roughly 15 fluorescent lamp watts per square foot at 12 to 15 inches above low-energy plants, at least 20 watts per square foot at 12 to 15 inches for high-energy plants, and about 10 watts per square foot at 6 to 8 inches for germinating seeds or rooting cuttings.
• Confirm the fixture is rated for the location. Aquarium hoods and damp growing environments require a fixture rated for those conditions; the lamp does not confer that rating.

Safety and Handling Guidelines

• Disconnect power to the fixture before installing or replacing the lamp.
• Allow the outgoing lamp to cool before removal.
• Handle by the lamp body; seat both bi-pin ends fully and rotate until the lamp locks in the lampholder.
• Fluorescent lamps are glass and contain a small amount of mercury. Handle carefully, avoid breakage, and follow local guidance for cleanup if a lamp breaks.
• Recycle spent lamps through an approved lamp recycler in accordance with federal, state, and local regulations rather than placing them in general waste.
• Keep lamps and fixtures clear of standing water; aquarium and greenhouse installations should use fixtures rated for the environment.
• Observe the recommended mounting distances above the plant canopy to avoid heat stress on foliage.
• Installation should follow all applicable national and local electrical codes.
