Double Ended Bulbs n reflectors

does anyon have experience with the DE bulbs n reflectors? They have a new model u can air cool but I hear they run really hot still.. my friend said they are way better and produce much more light tho so I’m interested in hearing others opinions on DEs

I’ve seen temps on my bulbs over 600f
Putting a bulb behind glass , is like putting a governor on your car. You will not get the most out of it.

If you can maintain a proper environment with a de1000, they can put out serious #
They are not very beginner friendly

Gavita makes a 750 hps that operates es efficiently at 600 watt too. Biggest issue is they are so bright and hot that you need load of clearance...meaning headroom. So no go in tents...
