Installation in 30 Seconds — No Tools Required

Step 1: Open the back cover, insert 3 AAA batteries (sold separately). Close cover.

Step 2: Clean the surface where you want to mount (wood, metal, plastic, tile — all work). Wipe dry.

Step 3: Choose your mount method:
• Magnetic: The back has a strong magnet — sticks to any metal surface (wardrobe handles, refrigerator, cabinet brackets)
• 3M Adhesive Tape: Peel the protective film off the included 3M tape, press the sensor onto your chosen surface, hold for 10 seconds

Step 4: Wave your hand in front of the sensor to test. Light should activate within 1 second. If it doesn't, check that the surrounding area is dark enough (the day/night sensor only allows activation in low light).

Step 5: Done. The light will now auto-activate whenever motion is detected in darkness, and auto-off after 15-30 seconds.

Why Choose Quick Sense Over Imported Brands

Most ₹400-800 motion sensor lights on Amazon and Flipkart are unbranded Chinese imports with no real warranty. When they fail (and most fail within 6 months due to weak PIR circuits), you have no recourse — return shipping to China costs more than the product itself.

Frequently Asked Questions

Are batteries included with the QS-MSL04?

No — 3 AAA batteries are sold separately. You can buy any standard AAA batteries from your local kirana store or Amazon. We recommend Duracell or Eveready for longest life. Total battery cost: ~₹100-150 for the set.

How long does the battery last?

4-6 months on typical household use (10-20 activations per day). Heavy use locations (busy corridors) may need replacement every 3 months. Daylight inactivity preserves battery — the sensor only activates in darkness.

Will it work during the day?

By default, NO — the QS-MSL04 has a built-in day/night sensor that prevents activation in bright daylight (saves battery). If you need daytime activation (inside a windowless closet, for example), cover the small light sensor with black tape to bypass it.

Can I install it on a wooden wardrobe door?

Yes — use the included 3M adhesive tape for non-metal surfaces. For metal surfaces (refrigerator, metal almirah brackets, kitchen cabinet handles), use the built-in magnetic backing.

What's the difference between QS-MSL04 and QS-MSL01?

QS-MSL04 has a bar shape (longer, suitable for wider spaces like under-cabinet lighting). QS-MSL01 is a compact square (better for tight spots like inside drawer corners). Both have similar 10-LED brightness and PIR sensitivity.

Can I use it outdoors?

No — the QS-MSL04 is rated for indoor use only. It has no waterproofing. For outdoor use, see our QS-SMS02 solar security light (waterproof, 2500 lumen).

Does it work with rechargeable batteries (NiMH)?

Yes — works with both alkaline (1.5V) and NiMH rechargeable (1.2V) AAA batteries. NiMH batteries provide slightly dimmer light but last longer per cycle and save money long-term.

What if my QS-MSL04 stops working?

1-year warranty serviced from our Faridabad facility. WhatsApp +91-8882553820 with your order number and photo of the issue. Most issues are battery-related and resolved over WhatsApp in 5 minutes. Genuine defects are replaced free of cost.
