anyway i thought the blue ones where the newest ... lumatek home website have blue ones ...
BGHydro said:No digital ballast is completely RFI/EMI-free, but the Lumateks appear to have the best shielding available. Older digital ballasts (including some of the older model Lumateks) actually interfered with cable, satellite and AM radios. The new Lumateks (1000W included) generate hardly (if any) interference outside of 10’. In fact, the RF interference shouldn’t even be strong enough to pass through a bedroom wall, even at distances under 10’.
Me to BGHydro said:How does the RFI on the 1000w/120v compare to the 600w/120v? Are there any proven / tested methods of things the user can do to help decrease the range, that you are aware of? Things like perhaps enclosing the device inside traditional RFI-shielding materials such as copper mesh, for instance. Or are those things effective on the low-power devices such as communication cables and such?
BGHydro said:Here is the answer I just received from Lumatek:
Lumatek said:Your answer was correct; there will be minimal interference (within 10ft) with the 1000 watt 120v while we currently experience NO detectable interference with the current (blue or purple) 600w 120v. Copper mesh and other traditional shielding methods are not much help as they are used as the customer noted on primarily lower wattage fixtures.
I was thinking of ordering one of these. havnt heard mutch bad or good about them. What i did hear was that it is designed to be used in greenhouses and when the plant gets 1meter+ tall the reflector gets problems spreading the light.cobo said:Has anyone got one of theses lights, seem to be very reasonable ????

globel said:I would not buy a ballast online or from a place i do not plan on going back to. Ballast go bad alot.... don't let the shop owners fool you. I suggest finding a retailer that has a good return policy. My local shop has replaced countless number of bulbs and ballasts for me on the spot no questions. He just packs it up and sents it back to the manufacturer. LUCKLY FOR EVERY ONE. My local hydro store is apart of a VERY LARGE FAMILY OWNED chain thers a GRIP of stores and they all have VERY VERY good policys on returens and stuff. Here is a place to see if they have a store neer you.

Also Ballast... lumiteks are ok but i have had a few blue ones go bad, without evean poping the fuse... Galaxies are ok but stay away from a 400 watt becuase i have never had a galaxi 400 last more then 3 months, i have had a few. Sunsystem coil balast SUCK BALLS every one i have purchesed 4 tottal have cought fire, all at diffrent times and some @ diffrent locations. But there is LIGHT at the end of the tunnel. There are these new ballast very hard to find. there digital 120/240 ballast. called Global Greenhouse Humbolt Holesale i think is the distributor. I think all the family hydroponics stores carry these ballast. I have never had a problume with any of these ballast. i am comming up on a year with my first set of 6 on the 12 of april =) time for new bulbs. Very soft start nevery had to reeplace a bulb in 12 months of opperation. QUALITY i have ran them on both 120 and 240 with no issues =) best ballast i have ever used, also no emi I use my cell phone in my grows all the time and we got fm radio going in there most of the time to. it sits on the tops of the cold ballast. frezzeing cold.
i think i found a family hudroponics ebay page and they sell the ballast from there. I wouls still go to the local store to get a ballast.
