Whats your favorite MH/HPS brand?
Im looking for a replacement 600w MH bulb. With a grow light kit I received an MH and HPS bulb, both "hortilife" bulbs. The MH is rated for 10k hours, but after about a little over 3k, the bulb has dimmed so noticeably that Im searching for a quality replacement that will last longer.
An example of the dimming: I have two 4 foot 4 tube T5HO fixtures on either side of the reflector with the MH in it. The MH is rated at 55k lumens, and the T5s combined at 37.6k. Running each separately, the T5s are very obviously producing more light than the MH.
The inner bulb is also grimy and the electrode areas turning blackish.
Anyway, what is your favorite and/or most recommended MH/HPS brand based on quality, life span, etc?
