LGH-40W All In One Solar Garden Light

The short version first: the LGH series is a complete solar lamp. Panel, controller, LiFePO4 battery and LED sit inside one housing, and once the battery is full it keeps lighting for a full 24 hours. There is no cable to trench and no electricity bill to explain to your customer.

The 40W model runs a 70W 18V monocrystalline panel together with 5050 LED beads at roughly 230Lm/W, which lands at 7200 lumens. Compared with the strip fixtures many buyers are used to, the light spreads more evenly and the shadows on the ground are softer.

What really decides whether a solar lamp survives year three is the battery, so we fit a 12.8V 36Ah LiFePO4 pack instead of cheaper ternary cells. It takes more than 2000 cycles, keeps its capacity in hot climates, and does not carry the thermal runaway risk older chemistries had.

Why This Model Sells Well

• No trenching, no cable: two brackets on a pole and the lamp is up. On rural and village work this is usually the single biggest saving in the budget.
• Keeps lighting through cloudy spells: the reserve covers 3-5 rainy days on normal mode, so a grey week is not a black week.
• Heat is handled, not hidden: the hollowed housing lets air move across the LED board and the battery, which is why we can talk about service life instead of only about warranty.
• Serviceable in the field: battery and controller are reached from the back plate, so a replacement takes minutes instead of a new lamp.
• Light where you need it: the 40W head suits 3-5m mounting height, and we quote panel and battery together so the numbers actually match.

Technical Specifications

One thing worth saying plainly: four models share one housing and one controller platform, so if a project grows you do not have to order a different lamp family. The panel, the battery pack and the lumen output step up together, and the mounting bracket stays the same.

We usually recommend matching the model to the pole height first and to the budget second. A 7200Lm head on a 3-5m pole lights a village lane nicely; put the same head on an 8m pole and you will be disappointed, no matter what the label says.

Charging takes about 6-8 hours of decent sun. Full-power runtime is roughly 10-12 hours, and in the 30% energy-saving setting the lamp can hold out far longer, which is what carries it through consecutive overcast days.

Inside Our Factory

LEADRAY has been making outdoor lighting in Shenzhen since 2005. The plant currently runs with 300-500 people, and 80-90% of what leaves the gate is exported, so export packing and export documents are routine for us rather than a special request.

We are not a trading desk putting our name on someone else’s box. Housing molds, die-casting, CNC machining, assembly and testing all happen in house, and there is an independent laboratory on site. Every LGH lamp goes through aging test, photovoltaic performance test, IP waterproof and dust test, temperature cycle test and a heat dissipation check before it is boxed.

Our solar lamp lines are already running on rural road, residential community, parking lot and park projects across Africa, the Middle East, South America and Southeast Asia. What that means for you practically: we know which configuration fails on a coastal site, which one is overkill for an inland village, and we will say so instead of just taking the order.

On top of the hardware we handle lighting layout suggestions, OEM/ODM customization, installation guidance, spare parts and after-sales support, plus a 3-year warranty. Distributors and contractors are welcome to come and walk the line before signing anything we would rather you see the lab than read about it.

Questions Buyers Usually Ask

Q1: What LED chips are inside the LGH lamp?

5050 LED beads running at close to 230Lm/W. Bright output with low decay, which is the reason the lumen figure still means something after a few years outside.

Q2: Which battery chemistry do you use?

LiFePO4 across the whole series, 12.8V, from 36Ah on the 40W model up to 80Ah on the 100W model. Safe chemistry, long cycle life, stable storage.

Q3: How long will it actually light up at night?

Roughly 10-12 hours at full power, longer in the 30% saving mode. The reserve is sized so the lamp rides through 3-5 overcast or rainy days.

Q4: How does the controller behave?

Light sensing plus time control. It charges during the day, switches on at dusk, and you can set working hours if you want to stretch the battery further.

Q5: Can you configure it for my project?

Yes. Tell us pole height, road width and how many consecutive rainy days you need to cover, and we will reply with the model, the panel size and the battery capacity that fit, not just the biggest unit in the catalogue.
