Ballast interference

So no info on the maxi bright ballast?. I done some research and the first maxi was mk1 model that was basically the phillips ballast re branded aka low F square, so rf and running the bulb seemed a none issue.

They don't seem to stock those any more and have likely ''reverse engineered'' the Phillips ballast to the best of ability or deliberately swapped out some components due to stock availability or expense. Mentioning that because the mk2 model is high freq and not square wave. It almost seems like phillips pulled the plug on providing maxi with gear so they panicked and knocked up a quick fix to deal with demand.

I say that because over on a uk forum a person counted 5 others who had a bulb fail ( the glass ball turning black) on them but some of them could have been down to be bulb instillation error/hood malfunctions. I must point out though, that it was five people of what seemed like 50 who reported using the maxi cmh for a long duration with no issue. But still, it leads to uncertainty as ttysk here pointed out in earlier threads that the bulbs can fail if not ran on the absolute correct ballast. It also makes me question how many of those 50 people are actually using the earlier mk1 version and are not aware of the differences.

For me it all comes entirely down to practicality and safety. If the mk2 interferes with wifi/radio.. it's a bad product imo.

Also don't see the point in knowingly risking what may be a small chance of having one explode due to improper freq/wave and just hoping the double jacket tech holds up.

Tbh I am hoping somebody here more knowledgeable can do a little leg work as they understand the frequency the maxi mk2 is running at/implications a lot better than I ever will. Not to be pushy but from a safety perspective I'd personally do it to warn others if I had that know how.

Speak to a local shop about any of this.. they don't have a damn clue. And unfortunately they seem to push the maxi pretty hard. Maybe theirs no issue and I'm paranoid.

The only possible way of guaranteeing no rfi/reliable firing is to have the ballast as close as possible to the lamp

high power==== gavita kits
low power=== Sun System cmh kit

is their a reason it must be a maxi ballast? GENERALLY, their is always a chance of interference with a remote (high frq) Digi ballast.......just the way it is, even with decent shielding

I don't think they have decent uk outlets. Maxi is the only reasonably priced one that comes with a majority of positive feed back. Although as said it's not the correct ballast for the lamp.

aaaaaaaah , you want to run the 315w agro cmh bulb..........yeah I only recommend Philips ballasts for their own bulb.

again sun system is the one you want, unless you can source the Philips locally

LSW have no issues with rfi, so your good to run it remote

5 out 50? is a high failure rate for these bulbs, I would avoid the maxi ballast then IMO

You have any uk prices that are not extortionate on the sun system, here's an example from ebay (are you sitting down?) £350 + £450 shipping. Sourcing in the Phillips ballast = about £300 last I checked o0.

Why Is American trading so shockingly pricey?

Yeah, it sucks..............can look at dimlux's(Holland) CDM option, expensive but known for extreme quality and UK availability

http://www.hydrohobby.co.uk/315-watt-dimlux-expert-cdm-ceramic-metal-halide.html even boosts the cmh bulb to 380w? never seen this before...........looks badass imo, horizontal positioning /reflector is a slight con.

edit....on second thought, that reflector has one bounce like cycloptics/98% miro silver,al/ adjust a wing like gavita.........very nice!

good luck

Yeah its a very nice looking light but really, who can justify such a price tag?. Also for such a pricey ''expert'' unit you'd think they would specify it's frequency, bulb brand/spectrum, uv output etc etc.. but nothing. And ontop of that, to take advantage of all it's expert built in features that no doubt jacked up initial price, you need a separate control panel costing a further £250. Nothing but a rich boys toy to brag about to his poor friends by the looks.

What would $1000 get you in cobs?.

Well you want your cake and eat it too? lol......... it's NOT that much more here than the other CMH offerings

http://growershouse.com/lights/ceramic-mh-reflectors-lamps-bulbs-grow-lights it's using the Philips 3100k , the spd can easily be found online, uv is low, ouput is 1.9ppf/w, ballast must be LSW to fire, light controllers always cost extra, it's a dutch company, I'm pretty sure it's reliable..........boosting the bulb last couple of weeks of flower is a nice option, don't know what that does to the ceramic/halide arc?..........you can email them for more info

$1000 if you DIY?, yes, more coverage and yield with cobs.........just frame up two of these easy kits

http://timbergrowlights.com/200-watt-cree-cxb3590-4-cob-meanwell-hlg-kit-meanwell-hlg-power-supply/ don't know what they charge for UK, shipping ? can ask , Dan has good customer service.

I know you are trying to help but you would not personally pay £520 for the base dimlux unit ($690). The optional control unit takes it to £770 - $1020. As said, if you pay the initial £520 price that is jacked up due to the added tech inside the unit, you would have to get the panel to use that tech and justify paying the extra cost on the base unit. If you don't get the panel you lose the tech and payed an extra £200 on the base model over the rival lecs.

Yes I do want my cake because this only covers a 3x3 footprint don't forget.

Was just wondering what type of W and coverage you'd get for $1000 worth of cob to show how silly priced the dimlux is with uk conversion rates.

Ive had this same question with the phantom 2 ballasts and the dude that makes the rfi protectors (Revolution Ballast EMI Filter) comes on this site and he said hes done all kinds of tests on ballast rfi and said its really not needed phantom ballasts or newer higher grade ballasts. hes very knowledgeable on the subject of ballasts and lighting his username here is "Revolution Micro"
