Stage lighting

Hello, I find that there is a lack of information on some products. In fact, some products don't indicate whether they're battery-powered or cable-powered. You can't see it on the photos either. So I can't make up my mind about the products.

Hi A filter according to lumen would be very useful for spotlights. Watts alone are not enough. 50 Watt LED is not as bright as 50 Watt halogen. Just an idea...
