G9 LED 240v lamp only lights when testing

[BobbyCliffs]

I have a ceiling light that uses G9 LED lamps. The lamps does not light when switched on. However, when I put my meter across the power supply to test if voltage is present the LED lights immediately. Once alight and the meter removed it stays alight until switched off. Switch it on again and nothing until I put the meter across the supply.

What is controlling it - a regular mechanical switch or a smart switch or dimmer? If it's electronic, is it definitely compatible with LED lamps of that wattage rating?
