35th China (Guzhen) Lighting Fair Opens Oct 22 as Battery-Integrated Lighting Takes Center Stage

High Temperature NiMH Battery for Solar Street Lights & Emergency Lighting | Guzhen Lighting Fair 2026

From October 22 to 25, 2026, the 35th China (Guzhen) International Lighting Fair returns to Zhongshan, Guangdong — the world's lighting capital — under the theme "Guzhen Lights Up the World." With more than 1.5 million square meters of exhibition space, over 3,600 exhibitors and 100,000+ new lighting products, it is the single most efficient place for lighting buyers to compare suppliers, test products and close deals in one trip.

But as buyers walk the aisles this year, one component is quietly becoming a make-or-break decision: the battery inside the luminaire.

Why Batteries Are Moving to the Center of the Lighting Industry

Walk through this year's fair and you will see the trend clearly. The show is showcasing solar + PV storage lighting, outdoor and landscape lighting, emergency lighting and smart lighting systems — all categories that do not work without an integrated power source.

For lighting manufacturers and distributors, the battery is no longer a commodity accessory. It determines:

• Whether a solar street light survives a summer of direct sun exposure
• Whether an emergency luminaire still works in a 60–70 °C ceiling void after years of standby
• Whether a luminaire meets environmental regulations (RoHS, REACH, heavy-metal restrictions)
• How often customers must replace the unit — and your brand's reputation with it

Heat Is the #1 Killer of Lighting Batteries

Here is a rule every lighting engineer knows: for roughly every 8 °C (15 °F) rise above room temperature, a rechargeable battery's cycle life is cut in half. A battery rated for 500 cycles at 25 °C delivers around 250 cycles at 33 °C — and only about 125 cycles at 42 °C.

Now consider where lighting batteries actually live:

• Solar street lights: battery compartments sit inside or under the luminaire, baked by the sun all day
• High-bay industrial lamps and plant rooms: ambient temperatures routinely reach 50–70 °C
• Emergency luminaires: installed in enclosed ceiling voids, stairwells, underground parking, kitchens and areas close to heat-producing equipment
• Outdoor and landscape fixtures: exposed to extreme diurnal temperature swings

In these environments, an ordinary battery ages and fails far faster than the LED itself — which is exactly why high-temperature NiMH batteries have become the standard engineering answer.

The Industry Direction: NiMH as the Natural Successor to Ni-Cd

The direction is confirmed by leading battery manufacturers' own application documents: rechargeable nickel-metal hydride (NiMH) cells are today's recommended chemistry for solar-powered street lights, emergency lighting, LED lighting systems, signalling, UPS and outdoor fixtures — replacing traditional Ni-Cd cells in almost every category.

Why? Because high-temperature NiMH combines what lighting products actually need:

• Wide operating temperature range — typically −20 °C to +70 °C or wider, covering both freezing winters and baking summers
• Long service life — dependable charge/discharge performance designed to match a 10-year lighting product lifespan
• True Ni-Cd replacement — longer cycle life, no cadmium, no memory-effect penalty
• Environmental compliance — recyclable and free of heavy metals, meeting today's export and regulatory requirements

If a lighting product needs to be charged by solar, sit in a hot enclosure, or be trusted in an emergency, high-temperature NiMH is the chemistry engineered for exactly that job.
