315 Watt Maxibright Daylight CDM Ballast

Post by Bulls » Mon Oct 07, 2019 8:21 am

Good morning GrowRoom420.





I've been running 3 of these ballasts for nearly a year now and I must say I am well impressed. As every other products there is a huge variety to choose from when selecting a cdm ballast. I was recommended Maxbright and here we come. These ballasts are recommended to be used with 315 Watt Philips CDM Lamps which I also highly recommend but that would be another review.

I'd say these ballasts run very quiet and at very reasonable temperature. I'd rate them better than my 600w Digital Lumatek ballast for sure. Here is some information from the manufacturer:
You get all of this, from a ballast that’s compact, light and silent – just what you need.


• No power surges (soft start technology)
• Prolong lamp life
• Low energy, to help prevent hot spots and lower running costs
• Incredible frequency control!
• Maximises beam pattern & light output of 315 Watt Philips CDM Lamp
• Silent to run
• Auto reset + short circuit protection
• Lightweight, compact & space saving – 230mm x 108mm x 68mm – (L x W x H)

Something very important with these ballasts is that they have protection. Once turned off, you won't be able to turn it back on for at least 15-20 minutes. The reason behind that - to protect the bulb ( And you will want to protect the bulb as they cost about 100£ ).

When connected, these lamps emit a smooth beam pattern, thanks to your ballast’s excellent frequency control! They’ll also kick out up to 1.9 micromoles (µmol) per Watt! That's crazy for a 315W supplemental lamp.

Now to get to the point - yield. I'd say that's very relative depending on your style of growing. 1 GPW can be easily achieved if you're using the most of the area covered by the light.

I had one problem with one of my ballasts recently. I noticed that 1 hour after the light come on, one of the bulbs goes off. If I unplug the ballast manually and plug it back in in 20 minutes It starts and runs without a problem, but if I leave it as it is, it would possibly turn itself back on in 40-60 minutes. I've contacted the Hydro Shop I bought the ballast from and they instantly replaced it!

Very very interesting indeed. I’ve seen these ballasts popping up a lot, well worth looking into I reckon.

Thanks for the info Bulls

Mine runs quite warm.

It does turn the lamp off when the ballast gets too hot too, but I've got one of my intakes ontop of it this grow and it's been faultless.

But yeah, I have opened the tent and it's been dark in the past, I've had the same with an MH bulb on a HPS ballast too.

Maybe i got some twilight zone portal in my house that doesn;t like MH bulbs.

:oik!:

They got thermal cut out protection in for the bulb and the ballast so the ballast don;t blow the bollocks out the bulb and vicey versey.

I just tell the plants a cloud passed over and they believe me. :oik!:

Hmm sounds like they run hotter than a digi hps ballast to me ?

So do you reckon these are as good as a 600hps for yield.

They run the same warmth I reckon as a 600 ballast.

Not quite as good as a 600 for yield, but not far off. Saves me a bit of leccy and keeps the temps in the tent down.

apt personally I think you cant beat HPS DE floor area.... cost and efficiency tho I think led and cdm are well infront - as is plasma. The problem is you gram per square meter - you wont beat hps

Okay guys nice discussion here but let me say something too..
Ballasts run slightly cooler than nornal digi 600 ballasts. I say that from running two of the ballast next to each other.
Something else very important. A single cdm light can't be compared to a 600w light BUT will produce better than 400w. Also CDM lights are always better when u have a few running. For example 3 of these lights are perfect coverage for my 2x1 m tent. If i was to run hps in there...2 x 600 will be waste. I won't even mentioned running 3 x 400w or 250w as it will hot as hell.
Mine never switched off in the summer too. Also my buds were almost touching the light ans had no light burn ot anything.

My conclusion is old time growers will always say hps for the win cause of results and cost but if you ever work with a few of these and see better final product and better cost in the long term you will make up your mind. I am truly impressed by the lights. But ad I like to experinment and from what I've heard these lights produce extraordinary results if mixed with hps so I'd do that next. Two of these CDMs on a side of a 600w hps in the middle.
