Eventually I led lamp did 🙂 very common fault that apartment lamp caused it in our region voltage 230v vicinity at night 240v is getting occasional spikes to come in the not to mention electronic circuit controlled economic CFL lamps is not based quality though often fail because they led lamp wanted to try.
I use LEDs in the base class from 5 `c 🙂 still a good performance at least provided adequate lighting for apartments
The main circuit 38 led FS-801 models sold in china I’ve changed a few supplies to use 50 LEDs
CAUTION Be careful is working with high voltage capacitor circuit connections Beware + – If you connect the high voltage polarity may be large explosions before running the insured Power Line circuit, protective goggles
470nF 50 LEDs LEDs per voltage 2.8V was around my hand though 1uF non-polar going to use there was in me 2 470nF 275V AC capacitor in parallel hooked about 950nf was capacitor connected in parallel with the resistor value 1Mohm did 220v input 1 amp fuse’ve added per LED 3.2v dropped
I use circuit transformerless LED lamp lighting
Mains voltage pointed the passive elements regulated by make LEDs run much healthier is not stable, for example, led one fails, all will be affected regulate whether the voltage is too high, if the LEDs are perishable, but russia, china popular in most countries, even those circuits in modules separate the sell so many have some sort of figure, lED lamps made way 20, 30, LEDs, 100 LEDs, 150 LEDs

Display Clock Circuit 74160 Counters
Circuit de 8 8 74 160 integrated and connected to the integrated display is available. Many types of designs made with one of the clock circuit. Every time displacing 74,160, and controlling for key control in an integrated and integral input are available. There are 4 key for each display. To see the adjustments in hours-minutes and seconds display units available for the three separate LOAD key.
