Is glass sheet needed between MH & water

I know that mogul base MH have a UV shield, but is a sheet of glass (or acrylic) between the tank and the bulb needed to prevent water splashes from hitting the bulb (and breaking it due to thermal shock)?

Thanks for the info.

I don't think it's needed. MHs are usually pretty high off the water line.
I do use a thin glass lid on the tank in the winter to help retain heat, but take it off when it's warm.

 

Thanks!

That certainly will make my hood design easier.

No problem. Good luck!

 

My MH came with a glass shield built in. If you are concerned, can you add glass in the hood?

 

I'd be very careful without a shield, if the bare bulb is exposed to water BOOM!!!!!!!!!!!

 

It would have to be a lot of water to make it go 'boom' I'd think. I have had little splashs hit mine without effect. Just wipe it off when it's off now and then.

 

Yah, I've doused may o MH, never had one go boom yet (from that at least). I have broken them with other objects on accident though, nd had one just go boom for no reason (coverred pendant-no chance of water enterring).

We had a trigger at our facility that could spit like 3' from his tank, to the invert MH. he got that thing pretty wet, it never missed a beat

 

I would be scared to take a chance. At the price of the bulbs why chance?

 

Chance what?

Why even get a MH, if your going to block a good portion of light out with the unneeded shield? IMO you should settle for t-5's until you feel a little more comfertable with MH's. I have EMENSE experience with lighting and I have yet to have a bulb blow due to water splashing on it.
