What's a good brand 600 hps bulb,good quality
I've personally started out with a 'low name' bulb called Emperor. It gives off a really red spectrum compared to Ushio and Hortilux and to be honest, I frigging loved it. I sought out to buy a 600HPS USHIO over Hortilux. Rocked the Emperor for 2 years, before I went out to buy the USHIO. 3 years later, never once did I think to go get a new bulb. (Saved up that cash to go buy material to upgrade the room)- light proofing, venting, new fans, gadgets etc..
We've been told to change out bulbs once a year, and some growers even change bulbs after every grow. I'm NOT about that life only because I'm cheap, not because I don't believe in it.
Anyways, USHIO is a great bulb for HPS in the sense that it'll hold that spectrum and lumens for longer before it starts to fade as compared to Hortilux and Emperor bulbs. *More red than hortilux i found..
Hortilux has a 'better' spectrum in terms of quality lighting and Lumen. It visually looks like it gives off a blue spectrum if you compare it to USHIO and Emperor, making it a 'fuller spectrum'. This does not in anyway make this a blue/cool light bulb. Still red spectrum.
I picked USHIO because I knew I wasn't going to replace it for a long time.. BUt HORTILUX is the Best all-round bulb if you're willing to get a new one every year. Stick with this bad boy.
Neither bulbs have ever burnt out on me yet..
