[600MRG] Low RF Noise LED Light Bulbs

[N1BUG]

I have LED bulbs by Ecosmart and Newleaf. None have produced any
detectable RFI on 2200m/630m/160m/6m/2m/135cm/70cm. I haven't
checked the HF bands. That said, my antennas may be a bit further
from my house than some. The 2200m/630m TX antenna is about 150 feet
away, the receive antenna closer to 200 feet from the house.

73,
Paul N1BUG
