The CMH lamps look to be the real deal. I would love to get one.
On another note about lighting - i did a trial run using the Solis Tek lamps. I flowered using the Solis Tek 400 watt 4K then switched to the 400 watt Solis Tek 10K finisher for the last 2 weeks. I was pretty impressed with the outcome. Yield suffered a bit, but I feel I could have done quite a bit better as I did this trial in a 36"x20" tent with only 2 plants (landrace Afghan Kush)
(Excuse my messy basement) i ended up with 6 colas like these. Buds were denser then what I get with HPS but there was ALOT more leaf then usual. I also feel like flowering took a week to 10 days longer also. Shit was sticky-icky like glue! I would love to see what these lamps can do with a proper sized grow are (3'x3') with like 6 plants or so. I think i would flower using these lamps for 5 weeks, switch to HPS for 2 weeks, then the 10K for 2 weeks.
