Bangkok, 17-19 September 2025. Booth B09, three days, and a steady stream of distributors, contractors and engineers from across Southeast Asia. This is one of the region's largest lighting shows, and for solar street lighting it arrives at the right moment: rural roads, town streets and resort areas are all moving off-grid.

The Lineup We Showed

We brought the full solar range rather than one series, because Southeast Asian buyers often handle several project types at once.

• LDT (20W-80W), LM (40W-80W), HBM (30W-120W): the volume all-in-one models.
• LCI / UCO / UCJ up to 200W: main-road and highway units.
• Split systems: for sites where the panel and lamp must be separated.
• Semi-split systems: a retrofit option with replaceable battery and LED modules.
• Garden, parking and CCTV-integrated lights: for compounds and security projects.

Demand by Country

The Retrofit Conversation

The semi-split design drew more attention than expected. Several buyers already have solar street lights installed, and the lamps are fine but the batteries are ageing. Replacing the whole fixture is wasteful; swapping the battery and LED module on a semi-split body is not. For a municipal maintenance budget, that difference decides how many poles get fixed this year.

“We do not need more lamps. We need the ones we already bought to keep working.” — Municipal engineer, Thailand

What We Learned About Service

The most repeated concern in Bangkok was not product quality. It was what happens after a failure. Island and rural projects in the region can wait weeks for a spare part, so buyers judge a supplier by the size of the box they keep on site.

We now recommend a service kit with each project shipment: one driver, one sensor and one battery pack per fifty units, plus a laminated fault-finding card in local language. The kit costs little, but it turns a three-week outage into a same-day swap, which is what the municipal engineer was really asking for.

Follow-Up

We left Bangkok with sample requests from three countries and an invitation to quote a coastal road project in the Philippines. The common thread: buyers want fewer models that cover more situations, and service parts that arrive before the rainy season, not after it.
