Saga of LED lamps. Poll

First of all, I want to say thank you to all readers for the positive comments that motivate them to act further. I admit, I did not expect such a vast public interest in such a rather narrow subject as the evaluation of the parameters of lamps, and therefore I was pleasantly surprised. I hope that the material that is being prepared now will not disappoint anyone.

Special thanks to everyone who expressed a desire to help me with the acquisition of lamps for tests. I am pleased to announce that now, thanks to the sufficient popularity of the first two articles, there was a sponsor who kindly agreed to help me with the purchase of lamps.

At the moment I am agreeing on a list of products for tests, and therefore I would like to ask the community which lamps are most interesting and should be tested first of all, for which I offer a survey. It includes the items that I currently have the opportunity to order.

As for the lamp from Ikea, I understood everything, it will be. I did not even include it in the survey - it passes to the final without a contest.
