advice on choosing LED device

[Raka]

I have been cultivating for a while in a 1.2 x 1.2 meter (4x4) space using 5 x 39-watt T5HO fluorescent tubes during the initial period, then switching to a 600-watt HPS light. Now, I would like to switch to LED lighting, mainly to better manage the high temperatures in summer. I would appreciate advice on which products to consider, keeping in mind that I have very limited knowledge about this technology, and I’ve seen a wide range of prices even for devices that (at least to my eyes) seemed to offer similar performance.

I would like to add that I don't integrate with CO2 and I am in the EU, so only brands/models that I can easily order from Europe.

Heat is a big issue for a tent. I have a 3x3 tent running a 242 watt ViparSpectra led (~600w equiv) - $160 or so on Amazon. Great performers for the money. That might be a bit low wattage for a 4x4. Most modern LED lights have a dimmer - important. Spider Farmer and Mars and others have good lights. My led will raise the tent temperature very little in winter.

What do you think of lumatek? Also comparing the prices of the various models from online retailers, I found the ZEUS PRO 2.9 - 465W at practically the same price as the ZEUS PRO 3.1 - 600W, now, would it be worth buying the 600w ZEUS PRO 3.1 and using it at 80%?

Just looked it up. Very nice light with a Samsung 301 driver. In a 4x4 tent that light is the minimum wattage I'd use. I'd run it without dimming after ten days of vegetative growth. Just raise or lower the light to 22" in veg and 18" in flower or whatever the manufacturer recommends. Sorry for the Fahrenheit and non-metric measures - we really are backward in the US.

Lumatek is good and I think the PRO 3.1 is the better choice.

It has 301H diodes, the driver is Lumatek.

The most affordable in the EU is probably Philzon if you order from Germany.

Lumatek are alright but not very affordable in the EU.

The Lumatek looks like a good light but it is expensive. Over $400. Similar wattage ViparSpectra lights are under $200 on Amazon in the US. Is it some VAT tax thing? After Greenland and Canada maybe Trump should take over Europe too.

Lumatek actually seems very expensive... I'm looking at this manufacturer, they're Dutch, and their products seem well-made. I also like the option to upgrade with UV and NIR... what do you think about it? DIMLUX - XPLORE SERIES LED | 800W.
I saw they also have a 730W model and a 730W 9-bar version https://dimlux.nl/dimlux-xplore-series-led-730w-9x/

There’s not much price difference between the three models, which one would you recommend?

I also looked at PHLIZON. The PHLIZON FD7600 800W Full-Spectrum+UV/IR
would cost me a little less than the Dimlux Xplore LED 800W.

The Phlizon FD7600 would be a better choice.

I looked at the Dimlux, not much information is given (ie diode count and type)

The Phlizon uses Samsung lm281b diodes, not the best on the market, but a solid choice for a budget light.

The FD7600 comes with an actual led driver as well, instead of a digital ballast.

Phlizon has also been in the game for awhile now, which to me is also a positive.

.

They do a 600w version. Fd6000

I own a few, they come with inventronics drivers, which are good.
and I own the lumatek 3.1 pro also.

Since you are in the EU you should also look at migro lights and definitely check his YouTube channel where he reviews most lights on the market

There's also options like this.

Basically any HPS ballast producer now make LED bar light and most of them use the same HPS ballast you already have, though this one seems to come with a proper driver

Thanks to everyone for the good advice. I’ve read positive reviews about the Lumatek Zeus Pro 3.1, and the price is around 1000 euro. I’d like to understand if it’s really worth the price difference compared to several models that, on paper, seem to have the same light efficiency and cost half the price. Anyway, from what you’re advising me, it seems like I can get a good device with a budget of 500 euro.
