Can I use single ended MH reflectors without the lens?
Does the lamps outer glass block the UV?

if splashed the bulb's casing can shatter and still operate... really nuking the tank's inhabitants. The shield offers some more insurance but will also reduce PAR some.

Yes, that could be a problem, I'm going to try to get some tempered glass that is not UV rated.
Thanks for the input.

I ran mine for a couple years with regular glass, no issues at all.

Cool, they are 250W Lumenmax2 and won't be enclosed in a hood so shouldn't get too hot.
Thanks for that.

if it's not actively cooled, a 250 watt will get hot... lol...

I ran 3 x 400w in Lumenarcs in a hood. They were fine. Yes, they get hot, so don't touch them :)

I like to go with experience, even tempered glass can break.
Thanks Brad
