Hello 420mag, been growing for around 8-10 months now, and think its time to get a new metal halide bulb since I bought it used when i started up, and the inside of the arc tube is pretty much black.. Ive been looking online and it seems hortilux makes several types of metal halide bulbs. Im not gonna spend 200$ on the super blue dual arc bulb, but the Hortilux M1000B/U/BT37/HTL Standard Metal Halide 1000W 4200K Grow Light Bulb (U Lamp BT-37) which is there standard mh bulb, and the Hortilux M1000B/BU/HTL Metal Halide 1000W 4200K Grow Light Bulb (BU Lamp BT-5). They are 2 different bulb shapes, and the standard says initial lumens of 115,000, and the second is 120,000 initial lumens. It seems they have the same spectrum, lifetime, and price. If the only difference is the initial lumens, ill pay 1$ extra for 5,000 lumens any day of the week..
Questions I have:
Which one works best?
Does one burn cooler than the other?
Using air cooled hood with 1000w sun systems magnetic ballast.
