LED tube replaces fluorescent
Due real Fluorescent lamp fire danger I have pretty much tried to get rid of potentially dangerous tradtional starters in the fuorescent lamps. So I replaced the starter with electronic safety model – if bulb does not start, it will stay off without heating. Or at least should. I got one Axxel S10 starter that →

The big lie about LED lighting lifetime
The great LED lightbulb rip-off: One in four expensive ‘long-life’ bulbs doesn’t last anything like as long as the makers claim article tells that many energy-efficient LED light bulbs failed before their advertised lifespan, tests have found. Disappointing result comes despite claims of them lasting 25,000 hours. The consumer watchdog and European partners tested five samples of →
