This is probably the absolute worst purchase buy I have ever made on Aliexpress. The lamp I would replace is at 5w and shines several times better than the new one which is both larger and should be at 10w. The picture of the slide is taken with my mobile phone on the screen I use and shoot with. The distance is about 200m. I have made a dispute but have not received any response from the seller. Choose another lamp and another seller!
I got what I bought! To my surprise, I got a USB lamp to illuminate the key. I can only recommend the store!
