LED lights are literally everywhere. The primary reasons for this is that they are energy efficient and cheap to run. Their purchase cost has considerably reduced over the last 5 years but they do have inherent issues relating to flicker, color (or colour in the Queen's English) and brightness. These can manifest themselves in lots of ways - for film makers (in the age of smartphones - nearly everyone is), users of nearly every modern form of domestic screen or lighting system, and for those with light sensitivity (headaches / migraines / visual strain from glare). This video explains how these lights work, how flicker occurs including pulse width modulation and how AC rectification is now available within newer LED bulbs. AC rectification will reduce / eliminate flicker but the other issues of blue light emission and lighting intensity unfortunately remain.

I am not sponsored in any way shape or form by Ledlam and I paid full market rate for my own bulbs. I am sharing this for the benefit of those who may find it helpful. Obviously, with time, prices will vary. This is the link to their website - [ Ссылка ]. They are not the only company that supplies these types of bulbs, and feel free to shop around, but I can tell you that these work really well.

I referenced a couple of position papers and these are their links:
