Expert Solution

Step 1

Since you have asked multiple question, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question.

In outdoor lighting, the IP44 grade is typical. You'll need a higher degree of protection if you need to jet-clean the light fitting or immerse it in water, but for the most part, the IP44 standard will sufficient.

A product with an IP44 certification is protected against solid objects larger than 1mm as well as water spraying from all directions.
Your product will be protected from solid particles larger than 1mm in size as well as low-velocity water sprays from all directions if it has an IP44 rating.
