I'm one of those who prefer the 'old school' indoor Christmas lights, therefore the filament/incandescent mini bulbs which look like tiny candles , each just over an inch long and maybe 3mm to 4mm in diameter. These give off a wonderful glow and often have a gentle twinkle function. I also prefer multi-coloured instead of just plain white. I'm very fussy about my lights. :-)
Trouble is that the old bulbs use a lot of energy, on the other hand LED bulbs are extremely cheap to run (just a few pence a week even at today's energy prices) BUT they are often harsh and overly bright and any 'twinkle' function is more like a maddening flashing sequence. They are also more often that not in the 'wrong' colours - they should be Red, Green, Blue and Yellow but these days they often throw in Orange, Purple, Pink and other colours.
Are there any indoor LED bulb strings which effectively mimic the soft glow of the older filament/incandescent mini lights? Either battery or mains powered? They don't need to by the mini candle shape Must be in the Red, Green, Blue and Yellow colours and also have a good twinkle function if possible.
Thanks in eager anticipation of loads of suggestions. :-)
