LED technically out of order

LED acquired, installed, very bright, well? No, after switching noise radios still in 6 m distance. Electricians thinks are not suppressed. Supplier contacted for return and pointed out noise. Standard answer, value below 40, -, postage must bear. Failure to state reasons has not been established. So postage costs and hassles and correspondence? No, from the garbage bag and from the nearest hardware store. Since you can exchange within a 14 day problems. If I buy directly from Amazon is also no such problems with the return. So I will in future avoid all market Place and other retailers. Taught me a lesson!
