Total teardown of a driverless LED.
Added 2017-03-17 00:40:57 +0000 UTCThese new driverless LEDs are getting very common because they are cheap. So here's what one looks like inside.

Why not try to smooth it out with a capacitator? Could you try and "fix" one?

2017-03-17 13:19:46 +0000 UTCIt seems cheaper to buy these off ebay.com than ebay.co.uk. I've noticed this with other electronics on ebay.
2017-03-17 11:28:53 +0000 UTCwould it be reasonable to think you could drive it with a high voltage DC power?
2017-03-17 07:01:01 +0000 UTCBTW, Banggood sell these as well and also do a 5 Watt version that is only 13 mm square. Great fixed to a largish piece of aluminium or coper as a passive heat sink. Or if you have a 12 volt DC supply at hand I find VGA style heatsink and fans just about perfect for the 5 watt version. I use two of the 5W ones under a 1.5m long kitchen cupboard were the water boiler is and I make my drinks which are operated automatically by a mains powered PIR switch that also switched them off when it hasn't detected movement for a few minutes as I always forget to switch them off otherwise.
2017-03-17 03:08:45 +0000 UTCWhat might be cool, if you make a few videos on how to refit LEDS into other things, I found some light bulps smaller ones used for older and motors are harder to find,
2017-03-17 02:46:43 +0000 UTCFYI, audio was poor in this video with the sound being very muffled whenever you were not facing forward.
2017-03-17 02:42:45 +0000 UTCWell the circuitry is the same, you just need to uprate the components appropriately. Though to be honest, it would be both much easier and cheaper to just find suitable LED without the flicker.
2017-03-17 02:39:56 +0000 UTCGoogle frequency multipliers, though I am surprised you couldn't find anything with the phrase frequency doublers. For though the first few results on Google UK are for Frequency multipliers, the fourth result onwards feature frequency doublers.
2017-03-17 02:13:12 +0000 UTCGoogle didn't help on this for me - is there such a thing as a frequency doubler for AC? Is that something that could be hacked on to reduce the flicker? I suppose you could also cut away some silicone and add a few caps.
