I have to agree. Recently on a JMFD from an extremely quiet RF location we noticed noise on 2 metres when the beams were pointed towards a supposed quality metal encased LED floodlight hanging from a tree and fed from a generator.
It turned out that the light and its connecting cable were radiating noise up to at least 2 metres.
We solved the problem by using a Ryobi 18v LED P720 20 watt Hybrid Work Light which has the double advantage of being able to use either 240volts or its 18 volt battery supply.
Dead quiet and very versatile.
