SoftTwinkle Slow Twinkling Christmas Lights (50 Lights, 17 ft)

In this review of the SoftTwinkle Slow Twinkling Christmas Lights, the bottom line is simple: these lights are for anyone who wants a calm, sophisticated twinkle rather than frantic flashing. The SoftTwinkle effect pulses each LED gently and independently, producing a slow, firefly-like glow that works well on a mantel, around a tree, or along outdoor railings. Our review found the string to be well built, energy efficient, and safe for extended outdoor use, making it a solid choice for seasonal decorators and year-round ambient lighting.

Key Features

• SoftTwinkle pulsing LEDs: Each 5mm LED pulses off and on independently to create a gentle, slow twinkling effect that feels natural and calming.
• Durable acrylic bulbs: Acrylic construction keeps bulbs virtually unbreakable and resistant to chipping, cracking, or color fading for long outdoor use.
• Energy efficient design: The string uses less than 5 watts and is ENERGY STAR certified, lowering running costs compared with older incandescent strands.
• Long run length and spacing: Fifty wide-angle LEDs are spaced 4 in apart across a 17 ft string to provide even coverage on trees, garlands, or banisters.
• Reliable connection and safety: Strings are UR listed, rated for indoor and outdoor use, and can be safely connected end to end up to 45 strings without overloading.

Who It's For

These lights suit homeowners and decorators who prefer a subtle, elegant lighting effect for holiday displays, patios, or ambient indoor scenes; the slow pulse is especially good for table centerpieces and bedroom mood lighting. Renters or seasonal users will appreciate the unbreakable acrylic bulbs and the ability to leave them outdoors without corrosion concerns.

Those who want very dense coverage or a large number of bulbs per dollar may want to look elsewhere, since the string has 50 lights over 17 ft and some buyers considered that sparse for the price. If programmable color effects or rapid flashing sequences are required, these intentionally slow, single-mode twinkle lights are not the right fit.
