Up to 6,773 poles, each costing THB94,884, were erected in Rachathewa Subdistrict Administrative Organisation's area.
A company that had lost in the project bidding emphasised that materials used in each part of the lamppost must be described clearly.
It explained that an instant post for the pole's base is THB4,500, cheaper than a spiral post that costs THB12,000.
An aluminium mould for the post's body would be more than THB1 million, while galvanised steel is THB45,000.
In Buddhist traditions, the kinnaras (male) and kinnaris (female counterpart), half-human half-bird creatures, are two of the most beloved mythological characters, which are believed to come from the Himalayas and often watch over the well-being of humans in times of trouble or danger.
