Which 24V IP67 power supply for LED 528 COB 15W/mb 4+5+4m instead of Mean Well 200W? 300Watt, but wh

I have LED lighting to install in the garden. I have purchased a 528 COB LED, which means I am assuming 15 W per mb. It has since turned out that the 200 W transformer from MEANWELL that I purchased will unfortunately not handle this for me (4, 5, 4 m sections). What trans power supply should I buy for this? What do you recommend, 300 W 24 V for such a length? IP67...

I intend to keep the power supplies in airtight boxes outdoors, ballasted with 5 cm of soil.

Would you recommend anything?

How about the Mean Well HLG-320H-24? It should do the job.

Thanks. I was thinking something about the ELG model, the HLG is hard to find and expensive. And of the Chinese no name ones has anyone used anything?
