Pros & Cons

Pros

  • ✓ USB 5V power from TV, laptop, or power bank - no wall adapter needed
  • ✓ 24-key RF remote works 19.6-26.2 ft away, no line of sight required
  • ✓ IP65 waterproof rating extends use to cabinets, stairs, and outdoor decor
  • ✓ Cuttable at marked points to size the 3.28ft run to your panel

Cons

  • ✗ 3.28ft covers only 32-46 inch TVs; larger panels need a second kit
  • ✗ 30 LEDs over 1M is sparse - expect visible hot spots up close
  • ✗ RGB color mixing only, no dedicated white channel for neutral bias light
  • ✗ 3M adhesive is single-use; repositioning usually means new tape

Manufacturer description

The SMY Lighting LED TV Backlight is a 3.28ft (1M) USB-powered RGB strip kit built for bias lighting behind a TV, monitor, or desktop PC. It runs on 5V drawn straight from a USB port on your TV, laptop, power bank, or phone charger, so there is no wall adapter and no separate power brick to hide behind the panel. The low-voltage input keeps the strip cool to the touch, which matters if the run sits within reach of kids or pets. A 24-key wireless RF remote handles RGB color changes plus flash, strobe, fade, and smooth modes along with brightness dimming, and it works from roughly 19.6 to 26.2…

Frequently Asked Questions

Will this fit my 55 inch TV?

Not on its own. SMY rates the 3.28ft (1M) strip for 32 to 46 inch HDTVs, so a 55 inch panel would need two kits or a longer strip.

Do I need a wall outlet to power it?

No. It runs on 5V over the included 3.28ft USB cable and plugs into a USB port on your TV, PC, laptop, power bank, or phone charger.

How far away does the remote work?

The 24-key controller uses RF rather than infrared, with a rated range of 19.6 to 26.2 feet, so it does not need to be pointed at the strip.

Can I cut the strip shorter?

Yes. The strip has printed cutting marks so you can trim it to the length that matches your monitor or TV bezel.

Is it safe to leave on with kids around?

SMY notes the 5V low-voltage input keeps the strip from getting hot, so it stays touchable. Keep the USB cable routed out of reach as usual.

What warranty comes with it?

SMY lists a 12-month warranty plus 90 days for free replacement or refund if you are not satisfied. Confirm current terms on the product listing.
