EMC and LED light
When LED lights came available, they were expensive. They were outperformed by a simple flashlight running on 2 D cells. The light spectrum was horrible, too. Good enough for the bathroom maybe, but not for a living room. Technology changed, fortunately. New LED light bulbs (bulbs?) are better than ever, cheaper than ever and the light spectrum is almost as good as the old, faithful light bulb (which I stockpiled).
LED Light Bulb, 44 pieces of 5050 LED's. The amount of light emitted by these bulbs is about equal to a conventional 40-50 Watt light bulb.
EMC
But what about EMC? No better way to find out than to buy a few on eBay. I paid less than $10 for two of these. That was a lucky find; normally they go for about $8/piece or so. I screwed both in, switched on my portable SW radio and held it close to the lamps, while checking all possible frequencies. Nothing. Nada. Zilch. No interference at all. This surprised me, to say the least. Other radio operators did report interference, and they bought respectable brands instead of cheap stuff made in China. I might buy a few more of these later in time. Or not, the expected life span exceeds 50.000 hours…

Interessant, ik gebruik 2 LED lampen. 1 in de gang en 1 op de overloop. Beide hebben een consumptie van 2W en geven ongeveer 20W aan licht. Nou heeft de vorige bewoner hier ooit de fase/nul verwisseld en staat de fase op de nul van de lamp. Gevolg is dat deze zelfs als de lamp uit is altijd heel zwak blijft “gloeien”. Hebben die nieuwe lampen die jij gebruikt dat ook nog?
Hallo Bas,
hier geen spoortje licht te zien als ze uit zijn.
