4 Foot T8 LED Tube Case of 30 10/12/15/18/24W 1500–3050 Lumens 3500K/4000K/5000K/5700K/6500K G13 Base Type A+B 120–277V

What wattage options are available for the 4 Foot T8 LED Tube?

The 4 Foot T8 LED Tube provides five selectable wattage settings: 10W, 12W, 15W, 18W, and 24W. This range supports both low-power retrofits and higher-output replacements without changing the lamp format.

What lumen outputs correspond to each wattage setting?

The lumen packages by wattage are: 10W provides 1,500 lumens, 12W provides 1,750 lumens, 15W provides 2,100 lumens, 18W provides 2,430 lumens, and 24W provides 3,050 lumens. This lets you match output to spacing, ceiling height, and target footcandles while keeping one SKU on the shelf.

How does 127–150 lm/W efficacy support connected-load reduction and ROI?

An efficacy range of 127–150 lm/W lowers the watts needed for a given lumen target, which reduces the connected load across large lamp counts. For ROI documentation, compare the selected tube wattage to the existing fluorescent lamp wattage plus ballast losses, then multiply the watt reduction by annual operating hours and the blended utility rate; add DLC Premium rebate value where applicable and maintenance savings from reduced relamping intervals.

What CCT options are listed for this model?

The specification lists three selectable CCT settings: 3000K, 4000K, and 5000K. 3000K is typically used where a warmer appearance is preferred, 4000K is a common neutral commercial setting, and 5000K is often selected for higher visual acuity in task-driven spaces.

What does the G13 base indicate for fixture compatibility?

The tube uses a G13 base, which is the standard bi-pin configuration used in most 4-foot T8 fluorescent fixtures. Confirm lampholders are in good condition and properly aligned to avoid intermittent contact issues during retrofit.

What does Type A+B wiring mean for installation planning?

Type A+B indicates the tube supports ballast-compatible operation (Type A) or ballast-bypass operation (Type B). The specification also notes compatibility with single- or double-ended wiring for Type B, which helps standardize retrofits across fixture variations while maintaining a consistent lamp selection.

Is this tube dimmable?

The specification lists 0–10V dimming. In practice, dimming behavior depends on the control strategy used in the retrofit configuration, so confirm the intended dimming method is supported by the ballast/driver approach specified for the project.

What certifications support rebate and compliance documentation?

The 4 Foot T8 LED Tube is cETLus Listed and DLC Premium Listed. These listings support safety documentation and are commonly used for utility rebate submissions where DLC Premium qualification is required.

What is the minimum operating temperature, and where is it relevant?

The minimum operating temperature is -4°F. This is relevant for unconditioned storage, loading areas, and cold-start environments where low ambient temperature can affect startup behavior and stabilized output.

What are the physical dimensions for fit checks?

The tube dimensions are 47.17" L × 1.29" H × 1.13" D. Use these dimensions to confirm clearance with end caps, internal guards, and any fixture components that can interfere with lamp insertion.

What warranty coverage is provided for this case pack?

This product includes a 5-year limited warranty. For maintenance consistency, document the configured wattage and CCT settings used for each area so replacements can be set to match the original design intent.
