Hey all, have an old light I'm replacing the light on for my parents.
Its says its a CHD model 100-5 500Watt 120V (its an old swimming pool maybe from the 60s or 70s, seems like this housing is an older one).

I'm guessing this is the part diagram for it:
I basically bought this gasket and light bulb:
1. Is the light fine? I saw inyopools also was selling 100W, 300W, 400W, and a 500W... just assumed I should 'match' what the housing says and have it be a 120V+500W light.

2. The 120V+500W light I got fits in the housing... the outer round part of the bulb sticks out a bit past the end of the metal end of the housing but the glass lens is also pretty curved so I think thats normal/fine?

3. Also do I need to put alot of silicon around the gasket before installing?
I have a small Danco Silicon grease... but wasn't sure if that is considered a 'sealant'...
But I see this bigger bottle of 'silicon sealant':

Like is one more appropriate for my use? Maybe both are fine but if i need more quantity then should I get the latter Boss one?

4. in that Inyo parts diagram they have that #7 bolt that tightens the housing enclosure+lens... Mine are like 40-50 years old i bet hehe... Any good replacements i can get? Simple standard size i can get from a local Ace Hardware?

Thanks if anyone can answer any of those questions.
