Unwanted delay in light Automation

Hi!

I want to turn on multiple lights at the same time.

I have so far tried automation, group lights and scenes but have been unsuccessful. The easiest setup seems to be an automation triggered by a time stamp as code example below. What happens when I run the automation is that the first light turn on immediately but there is an (exact) delay of 10 seconds between each following light turning on. Adding more lights to the automation adds additional 10 seconds of delay between each light turning on. If I trigger two lights manually they both switch on immediately.

Any advice is most welcome!
