LEDYA 21051 Cool White Icicle Lights, 17m, 480 LEDs

LEDYA 21051 icicle string lights provide 17m of cool-white lighting across 480 LEDs, with eight selectable effects for indoor or outdoor seasonal displays. Mains power, a timer and a memory function add convenience, but the listing gives conflicting timer schedules and material details to verify.

At a glance

Eight lighting effects include steady-on, sequence, wave and fading options, selected using the button on the plug.
The lights are listed as 17m long, with an additional 10m power cord and a 10cm end connector. The listing says up to three sets can connect.
A memory function is claimed to retain the last selected mode.
The listed timer activates by pressing the plug button twice. Outdoor-use claims exclude the plug, which the listing says must be protected from water.

Pros and cons

Pros

The 17m illuminated string and 480 LEDs suit decorating a longer eave, window line or garden boundary.
Eight effects and a remembered last mode offer varied displays without needing to reselect the effect each time.
Mains power avoids relying on replaceable batteries.

Cons

The string is stated to be non-detachable, so its layout cannot be split into shorter sections.

What to know before buying

Listing details to confirm

The listing gives inconsistent timer schedules: 8 hours on and 16 hours off in one section, but 6 hours on and 18 hours off in others. It also inconsistently describes the material as plastic and as copper and plastic. Customer feedback is mixed on cable length and reliability, and includes reports of early rusting and some bulbs not working. Check the schedule and the intended run before purchase. The plug is not waterproof and needs protection from water.

Customer feedback highlights positive impressions of the lights’ appearance, brightness, colour and perceived quality. Experiences are mixed on reliability and cable length, with some reporting failures such as half the bulbs not working, and reports of rusting after a couple of weeks. That matters for a 17m mains-powered installation, where reach and dependable operation are practical concerns. These are reported customer impressions, not verified product performance.

Positive themes

Customers describe the lights as bright and attractive, with positive comments on appearance and colour.

Negative themes

Some customers report rusting after a short period.

Mixed feedback

Feedback on reliability varies, including reports of both lights working well and some bulbs not working.
Cable length is described as suitable by some customers and too short by others.
