70L 4" Spacing Mini Lights - Strobe

Why the 70L 4″ Strobe Mini Lights earns its place on the contractor truck

5mm LED strobe mini lights with 4-inch spacing for contractors who need eye-catching motion in the display. The flickering strobe effect adds dynamic movement that pulls attention from across a parking lot or down a residential block — the upsell that turns a standard wrap into a premium one. 70 bulbs packed onto 24 feet of wire delivers the same density as the standard 70L 4" strings, with the added visual impact of the strobe effect.

Built for the Job

70 strobe LEDs on 24 feet of green wire. Bulbs spaced 4 inches apart — tighter than the standard 6-inch layout — for a denser, more concentrated display. Same string length range as a 50-count, but with 40% more bulbs per foot. Trees look fuller, hedges look brighter, and the strobe effect reads from farther away than steady-on lights would.

Built-in strobe effect. Each bulb flickers in a random pattern that creates dynamic visual movement across the strand. The effect adds energy and motion to displays that would otherwise be static — ideal for commercial properties looking to stand out, holiday villages, photo-driven residential installs, and any job where the customer wants the display to feel alive rather than just lit.

Run up to 45 strings end-to-end. Each strand pulls just 4.8 watts, so you can chain long runs from a single power tap without tripping breakers or running extension cords across the yard. Big trees, long hedge lines, full property wraps — all on one circuit.

One-piece sealed construction. Bulb and wire are molded as a single unit, so moisture can't migrate into the connection and corrode the contacts. This is the failure point on cheap mini lights, and the reason these last multiple seasons in outdoor conditions.

Virtually unbreakable bulbs. Wide-angle LED housings won't shatter when a ladder bumps a branch or a string gets dropped on the driveway. Colors won't fade, chip, or crack across seasons of UV exposure.

Up to 50,000-hour rated lifespan. Long enough that the bulbs outlast the wire, the storage routine, and most of the homes they get installed on.

Designed for Speed

Pre-balled for fast wraps. Strings come ready to deploy — no untangling on a customer's lawn at 7 a.m. Pop the ball, anchor the lead, and wrap. The 4-inch spacing means denser coverage in fewer passes around the trunk.

90% less energy than incandescent. Lower draw means more strings per circuit, fewer power taps, and lower seasonal operating costs you can pass on as a selling point to commercial accounts.

UL 588 listed. Safe for indoor and outdoor use, residential and commercial — the listing every legitimate install needs to be on.

Where Strobe Strings Win Jobs

Strobe strings are the upsell product in the mini-light category. Use them when:

• Commercial properties want maximum visibility from busy streets or parking lots
• Photo-driven residential installs need motion in the image for social media content
• Mixed displays need a focal point — strobe a single hero tree against steady-on perimeter wraps for visual hierarchy
• Customers ask for "something different" than what their neighbor has
• Holiday villages and themed installs need animation that catches the eye

Strobe lights are also the easiest "good-better-best" upgrade to offer in a bid. Quote the standard 70L 4" string as the base, the strobe version as the upgrade, and let the customer choose which level they want to pay for.

70L 4″ Strobe Mini Lights vs the 70L 4″ archetype

How to install 70L 4″ Strobe Mini Lights

1. Plan the run length. Sum the per-string lit length. At ~23 ft per string, plan tree/bush coverage accordingly.
2. Pre-test before wrapping. Plug each string in BEFORE wrapping. Swap dead strings now — not after wrapping.
3. Wrap from base outward. For trees, start at the trunk base and spiral outward toward the tips. For bushes, drape across the surface and tuck behind branches.
4. Chain end-to-end at the integrated connectors. Up to 3-4 strings per chain. Don't exceed the in-line fuse rating.
5. Power the end of the run. Plug into a GFCI-protected outdoor outlet and a LED-rated outdoor timer. Don't exceed 80% of circuit capacity per code.

Build quality + materials

• Pro-grade LED bulbs — 5mm or coaxial-concave optic depending on variant. Sealed bulb construction resists moisture entry across multiple seasons.
• UV-stabilized wire jacket — survives outdoor cold-climate exposure for the full residential season; pull at takedown for 5+ seasons of clean reuse.
• Strobe (synchronized flash) hardware circuit — effect runs without a separate controller — plug and play.

Warranty

1-year manufacturer warranty on 70L 4″ Strobe Mini Lights from Christmas Lights HQ. Covers manufacturing defect and bulb failure rates above 1% per season. Not covered: chain overcurrent (>max-in-series), damage from outdoor cold-climate without GFCI protection, year-round outdoor exposure beyond seasonal use.
