LF-YT02 All-in-One Solar Street Light
The LF-YT02 packs a monocrystalline panel, a LiFePO4 battery and 306 to 510 high-efficiency LEDs into one die-cast aluminium body that is just 87 mm deep. No trenching, no cabling, no electricity bill — it charges by day and lights automatically at night.

Four Core Advantages — and Why This Slim Body Suits Tight Projects
These are the choices that decide whether a solar street light is still working properly in year five.
01 An 87 mm body — slimmer than a standard all-in-one
The whole luminaire — panel, battery, controller and LEDs — is 87 mm deep. A slimmer body presents less frontal area to the wind, so the load it puts on your pole is lower, and one unit ships in a carton of only 0.04–0.05 m³.
02 Brand-new LiFePO4 cells, 3,000+ cycles
We use brand-new lithium iron phosphate cells rated for more than 3,000 charge cycles. We do not use second-hand or graded-down cells — the battery is the first thing that fails on a cheap solar light, so we do not compromise on it.
03 Monocrystalline solar panel
Monocrystalline silicon, with a photoelectric conversion efficiency above 23%. A monocrystalline panel generates more power from the same surface area than a polycrystalline panel, which matters when the roof of the luminaire is no larger than the body itself.
04 306 to 510 LED chips, 160 LM/W at the luminaire
A dense 5054 SMD array gives a smooth, even spread of light rather than a few bright spots. That 160 LM/W is measured at the complete luminaire, not at the bare chip.
Light Where It Is Needed, Not In Your Neighbour’s Window
Where a street light puts its light is what decides whether it works for the road or annoys the neighbours. The LF-YT02 uses intelligent PIR induction control: the sensor recognises human activity and separates it from other interference, so it triggers accurately rather than on every passing shadow. When the road is empty the light steps down to a low output and returns to full brightness as someone approaches — lighting the people who need it and saving energy on an empty carriageway. Light-control switches it on at dusk, the timer sets the burn hours, and the battery is protected against deep discharge. We size the optics and the battery to your road width and your nightly burn hours, and every quotation comes with a DIALux simulation built on your own road geometry. The two figures below are the evidence that goes with it.
What Is Inside the Housing
LiFePO4 Battery Pack
New cells, 3,000+ cycles, housed inside the die-cast body so it stays within its working temperature range.
Monocrystalline Panel
Tempered low-iron glass, conversion efficiency above 23%.
An 87 mm Die-cast Aluminium Body
Aluminium throughout, for oxidation resistance and a body that stays light without giving up strength. The whole assembly is 87 mm deep — a side profile that is easy to carry up a pole.
How Your Order Leaves the Factory
Each light is packed 1 piece per carton — 0.04 to 0.05 m³ and 6 to 7.8 kg net per unit, and packed 1 PCS/CTN. Before the container is sealed we photograph the finished goods, the packing and the container number, and send those photos to you — so you know exactly what was loaded.
Four Inspection Gates Before Anything Ships
Every order passes incoming inspection, in-process inspection, final inspection and pre-shipment inspection. Production progress is photographed at each stage and sent to you, and a quality report is issued before the goods leave. Third-party inspection is welcome.
IQC — Incoming
Solar panel output, battery capacity and internal resistance, controller function, LED chip and driver, housing casting quality.
IPQC — In-process
Housing preparation, LED module assembly, wiring polarity and earthing, seal integrity before closing.
FQC — Final
Full power-up, waterproof spray test, photometric measurement, ageing test, and a simulated solar charge/discharge cycle.
OQC — Pre-shipment
Sampling inspection against the order, accessory and document check, packing and container photos.
Where the LF-YT02 Is Used
Roads, Highways and Streets
Municipal roads, community access roads and rural highways where laying cable is expensive or impossible. Suitable for government-funded projects.
Rural and Residential Areas
Villages and residential compounds where there is no reliable grid connection. Installation takes minutes and needs no specialist electrician.
Industrial and Commercial Sites
Factory yards, warehouse perimeters, logistics parks and commercial streets. Cuts both cabling cost and ongoing electricity spend.
Parks, Squares and Car Parks
Public open spaces, parking areas and walking paths, where a clean look and zero cable trenching matter.
