Dimlux 630w CMH Expert series issues, anybody any ideas how to fix?

I think I will start without the LEDs for now but will keep that in mind.
Decided to order from another EU country where I can get the Gavita 630w CMH fixture plus 3 spare CMH bulbs plus the couple things like ventilation duct I need to replace and a nice big helping of great white shark mycorrhiza for 600 bucks all in free shipping. Seems like a good deal and I will have everything to start with.

I was trying to squeeze an LED or 2 into the order instead of the spare CMH bulbs but the only ones I found in the 100 € range were advertised as only for seedlings/early veg.

There was a Lumatek fixture that I liked in that price range but it also needed a sold separately starter which pushes it above 200 bucks again. and for the 1.20m X 1.20m I think that would be overkill/a waste.

I think its much better if I get 4 light strips at the right light range and solder them myself down the road. A single strip/rail would also be much easier to mount on the sides than a fixture that is meant to be hung from the ceiling.
But thats for down the road, gotta get cooking again first, make sure my VPD is better this time around and I get the organic soil in check without running into friggin gnats and the like again.

Last time I stopped growing I had just made the swap to grow in large beds instead of big fabric pots and had a feeling I finally got rid of the gnats and other buggers that way. But then I had to stop due to a family tragedy and could never really conclude.

Yeah I've cooked my fair share of tops lol at this point I almost expect it, but the rest of the plant is all top shelf quality stuff. I use an old timber growlight 5 cob setup with the 2 cmh systems on each end of a 4x8 raised bed and couldn't be happier. And yes I've used the spider farmer panels for cheap side supplemental light too usually black friday or cyber Monday I'll snag 2 or 3 of them for a great deal. So far I've only had one burn up but it was pushing 4 years of heavy use so 🤷 I can't complain. Come to think of it my cmh sunsystem is gotta be pushing 6 or 7 years old now.

Yeah that was another thing that convinced me of CMH. I did get a lot of runtime out of them, only once had to replace the bulb. My Dimlux experience was apparently way better than that of others.

Looking forward to receiving that Gavita, they used to be top of the crop and not at all affordable back then. Now I get one for less than 300 bucks lol

I also went ahead and got 4 of those

ViparSpectra PRO Series P600 100W​

to mount in each corner. All giddy to find out how that will work out hehe
