I just don't understand physics it seems....as how can there be that much energy savings if so much heat is produced and must be dissipated? Here in the VI when the power company increased the rates to over $40 per KWH everyone bought the cheap CFL bulbs after the energy office made a big promotion on radio and TV about how much money would be saved in the process. Well there was less consumption and people bills were slightly lower with this and other energy saving moves like turning of the electric water heater, going to gas stoves, and unplugging the freezer part of the day. OK fine but when the power company noticed a reduction on accounts receivables, and found it difficult to make bond payment on debt service...guess what? They just increased the per KWH charge to about 50 cents per KWH!
So whats the point in saving a few watts anyway if these LED beasties cause RFI? in fact i like the old incandescent bulbs that haven't changed much since Thomas Edison and others in UK and Russia invented them. plus i like the fact that when I key my rig on TB the outside lights at night go off and on. (Just kidding of course) Herb, KV4FZ Wayne.. Good info...Thanks.... Hmmm.. the heatsink base of this 40 watt bulb also gets too hot to touch and feels like more than 40 watts also. --- On Thu, 4/5/12, Wayne Mills<n...@bresnan.net> wrote: From: Wayne Mills<n...@bresnan.net> Subject: RE: Topband: Home Depot LED bulb interference.

I even disconnected the shield on the RX input this morning and still don't hear anything. Wayne, N7NG p.s. That 75 watt equivalent lamp seems to put out MORE than 60 watts of heat. It really gets hot. -----Original Message----- From: topband-boun...@contesting.com [mailto:topband-boun...@contesting.com] On Behalf Of Jim F.

I bought two LED 40 watt equivalent 110V. light bulbs from Home Depot that use only 9 watts of power, for $9.99 ea. They seemed like a good deal but cause noise interference on 160m and the FM radio band. (I did not try other bands.) I like the bulbs but best use them away from your radio station and have someone turn them off and on while monitoring your favorite frequencies/bands. 73, jim / W1FMR _______________________________________________ _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
