I'm just about to reorder this Vivosun 600w mh when I noticed it said conversion..

My veg plants love it, but most other 600 watt MH do not say 'conversion' and are 6000k

I'm curious why this says conversion and more so why it's 4200k instead of 6000k ?

Which Kelvin rating is best for veg ?
-thanks

Found my own answer, heres a quote from hortilux:

    • Please note that there are no 600W Metal Halide core and coil ballast. They do not exist in the general lighting industry. That is why ALL 600W Metal Halide lamps are conversion lamps designed to run on HPS core and coil ballasts.

    Humm.. Learn something new everyday I suppose ?
Still not sure which Kelvin rating is 'best', I suppose that's debatable :/ but I've had good luck and great growth with Vivo Sun & I've got to order in >3 hours to get them here by Sunday so I'm going to reorder now

Took this Romberry pic this morning under a VivoSun HPS

So while I'm answering my own questions this would pretty much answer the Kelvin question too:

Edit: I went with the whatever the hell the other brand above was 600 watt MH because I thought the 6000k might give me thicker stems in veg? I thought they seemed kinda stretchy last 6 months because of the hot summer temps but it might have had something to do with the 4200 Kelvin VivoSun MH?

Thanks for the input I'm aware some come with yellow inside, but would you accept that bulb as new? It's literally more burnt looking than what I'm taking out?

Here's the pictures from their website above, does it look like that or does it look burnt? (looks burnt to me)

Edit: so I looked again on Amazon at a million mh bulbs and the Apollo was the only other bulb that seem to have crap going on inside (but not burnt), but either way that bulb is not staying here: it looks more burn than the one I'm replacing not even joking

No shit right! ..it always bites me in the ass, I just got a beautiful vivosun 1000 HPS Sunday I'm getting another Vivo Sun MH when I send this piece of work back.

Here's the new VivoSun, came Sunday, this is what a new bulb looks like for those unaware. I'm sticking with this brand.

If you're paying less than $20 for a bulb you're getting what you pay for. Crap.

It is normal for some bulbs to have solids in them that vapourize after the light heats up.

I like my Hortilux bulbs. The plants like them too. I only have 400 and 1000W magnetic ballasts and still use a 17 yo 400W MH conversion bulb that runs off an HPS ballast.

Just got a 400W Philips CMH bulb from a buddy and it's intensity is almost as high as my near new 400W Hortilux Super HPS. Running both over a 4x4' ScroG screen with 6 plants tied into it. Just 2 full days so far and they are really perking up after idling under the old conversion bulb. Another week and I'll flip to flower but may switch to a 1000W on my light rail. Choice between a Light EnerG Super HPS or my really good Hortilux 940W HPS conversion bulb. It runs off of a 1000W MH and I have two of those.

Would like a couple of 600s but not in the budget atm.

You and the other guy did you even look at the burnt bulb? That's exactly what the other guy said which is why I said if you want to know what a new bulb looks like? Why don't you look at the first bulb?

I could put the first picture of the burnt-out protopia bulb that they sent me next to the burnt-out old one that I just replaced and they look almost identical did you even look at the bulb?

I'm going to put up a thread regarding this brand and make a poll and let people vote new or used for the bulb, it amazes me how people can look at a burnt old bulb and want to tell me it's new forget about it

have you ever tried running a 10000K MH at the very end of flower as a finishing bulb? supposed to really increase the trichs.

Yes I have a thread in Advanced thats similar, I ran a thousand watt metal halide one week out of the month in my Perpetual flowering tent but I stopped because I didn't notice any difference and it was a pain in the ass changing bulbs if I'm honest

So I'm going to make a thread with just pictures and add a 'New or Used' poll so people can vote on the bulb just so I know if people can actually tell a burnt bulb compared to a new bulb?

was it the 10000Kelvin bulb or just a regular 5 or 6K metal halide?

They were the basic bulbs, The hps was Vivosun 21000k, the metal halide was Hydrofarm 6500k, my reason for doing this was adding UV from the halide over the course of the entire Perpetual grow, however what you said about the 10,000k was also the answer I got in the aforementioned thread, which is another reason I gave up on my little experiment

Also to old medgrower1, deleted that quoted post almost immediately (but apparently not fast enough) because it sounded snarky and I read you quite a bit and didn't want it to sound that way, but look at the bulb it's burnt, not new!

If you go to protopia and read their reviews a lot of people are saying "I just got the bulb and it burnt out in a few weeks or a month", now I know why?

The trouble with the Perpetual is there's never a proper time to 'finish'?! Although if I ever get a little extra cash I'll probably pick one of the 10000k bulbs up and try it because I do believe that ultraviolet needs to be added, or at least should be added if possible

I thought by adding MH 1 week of the month I could supplement UV that way but then I found out that the finishing bulb is the proper UV supplement and the regular bulb has just so little that it wasn't worth swapping it out so I stopped my little experiment

The one thing I noticed is that when veg plants were put into flower under mh it did not stop or even cut down the stretch at all, at least not that I could notice?
