I ordered a Reeflux bulb online because a friend of mine swore by them...he said that the 10ks looked like other brands' 14ks....So...I got it and it really did look like a 14K next to my really bright Ushio 10K....so I kept these 250 watt DE halides next to each other for a couple of months and didn't really notice a significant difference in growth....at first I wasnt too sure about the Reeflux, because it didn't come with the Reeflux box...and it was awful blue for a 10K light..but I really started to like it...so I order another Reeflux 10k and it looks almost exactly like my Ushio 10K...if not worse...someone didn't sell me a true Reeflux...this one had the Reeflux box,..but still no stamp on the bulb....How can you tell......ANY RECCOMENDATIONS??? HELP!!
