The right magnetic light bar depends on where you’ll use it and how bright you need it to be.

• Garage/auto work: Look for higher output (around 1,000–3,000 lumens), strong magnets, wide light spread, and an IP rating for dust/splash resistance. Hooks or straps help under-hood use.
• Kitchens/closets: Slim, rechargeable bars with motion sensors (Auto/On/Off) and dimming are convenient. Warmer color (around 2700K–4000K) is easier on eyes for home spaces.
• Desks/reading: Choose adjustable color temperature, stepless dimming, and a diffuser for softer, anti-glare light.
• Fit and power: Check length, battery capacity (mAh), charging port type, and whether you prefer plug-in or cordless.

Run time varies with battery size, brightness level, and mode. As a general guide (actual results can differ):

• Under-cabinet lights: In motion/auto mode, they may last several days or longer between charges. At continuous high brightness, a compact bar might run a few hours.
• Work lights: Larger bars with higher lumens often run longer on lower settings and shorter on turbo/high.
• Plug-in options: Provide continuous light but require a nearby outlet.

To extend runtime, try dimming, using auto modes, and charging fully before use. Some models can operate while plugged in—check the product details. Battery capacity (mAh) and any stated runtimes on the Walmart product page can help you compare options.

LED magnetic bars are versatile, but a few trade-offs may apply:

• Mounting limits: Magnets won’t grip non‑ferrous surfaces (wood, aluminum, some stainless). Many kits include adhesive or metal plates as a workaround.
• Glare or harsh color: Without a diffuser or warmer color settings, light can feel bright or cool. Look for dimming and adjustable color temperature.
• Recharge downtime: Cordless bars need periodic charging. If you need continuous light, consider plug-in styles.
• Surface care: Strong magnets can scuff delicate finishes. Clean surfaces and use protective pads if provided.
• Sensor quirks: Motion sensors can trigger from pets or reflections; sensitivity and placement matter.

Installation is usually quick and tool‑free. These steps can help, but always follow the product’s instructions:

1. Test the spot: Use a fridge magnet to see if the surface is magnetic. If not, plan to use included metal plates or adhesive strips.
2. Prep the surface: Wipe clean and dry for better grip. Let adhesives cure as directed.
3. Mount and aim: Attach the bar, angle LEDs away from direct eye line, and position sensors to face traffic.
4. Charge first: Fully charge for best initial performance and to check all modes.
5. Mind heat and moisture: Keep clear of stovetops, steam, or damp areas unless the light is rated for it. For under-hood use, secure hooks/straps and remove before driving.

On Walmart.com, product pages list mounting hardware and instructions to help you plan.

Magnets stick to ferrous metals (like most steels). Many kitchen cabinets are wood or laminate, and some hoods use non‑magnetic stainless or aluminum, so a magnet may not hold.

• Quick test: Try a simple fridge magnet on your surface.
• No metal? Most light bars include adhesive strips or metal mounting plates that create a magnetic spot.
• Protect finishes: Clean first, and consider using protective pads if you’re worried about scuffs.
• Under-hood use: Ensure a solid mount with magnets or hooks and remove the light before driving.
