I need new bulbs for my T5 Fixture.
I seen this on eBay would you guys recommend them or not ??
Do you have SPS? My guess is you'll likely not get the same level of quality control for spectrum or output as you would from ATI or Giesemann.
Me personally, I have spend $$$ on SPS and would not risk their health over $100 a year in bulbs; however, if there was supporting data that showed these bulbs keep up with the leading brands, totally.
If you have softies and LPS, you may be able to get away with it.

If you dont plan on having corals, it doesnt matter. If you do, stick with ATI or Geismann. Looks like they offer blue (460nm which isnt quite actinic), white (6500k), and 50/50 (10,000k) essentially. Two of each (actinic and 6500k) would look nice together and all 10,000k would also look nice (visually). Two 10,000k and two actinic are nice if you like a bluer look.

I agree with @madweazl Those bulbs will be totally fine for a fish only or softy system. If you start keeping SPS or more light demanding LPS, definately switch over to one of the proven brands.

Is there a brand in the description? If they are Narva they are / were just as good as ATI and Geiesmann. Made in Germany even but I believe they closed the manufacturing plant.
Odyssea I belive. Possible made by Hamilton and likely a coralife bulb.
Perfectly fine. Not great. Buy an extra set.

They are not marked like Odyssea and do not have the same end construction, but they could be. They are from China, I think... not sure... but I think... they do not have china stickers on them like they are supposed to, but they most likely are.
I have some that I use over a fuge and a shallow frag tank. They are fine. They test out to about 250 PAR in a 4 bulb Hydroponics fixture about 8 inches under the tank. I would use them in a heartbeat to light FOWLR, softies, LPS and the easier acropora. I might want the higher powered ATI fixture and some better bulbs for clams and the higher light acros.
If you want nice, good, cheap bulbs, GE 6500K are cheaper than this and high quality.

It’s top dog sellers. Odyssea or whatever other names it uses whenever. Like jeabo jacod does.
The 8000k and 10,000 temp out at the Kelvin’s advertised with my meter.
Can’t Color temp an actinic though.
I ran a 5g pico with thier CF combo 10/actinic buld and rgbw Leds for four years or so.
Best growth I’ve ever had on a blasto Merletti .
I have no issues with the bulbs. They hydroponics fixture that I have them in is not great, but it grows chaeto, dragons breath and dragons tongue out of the tank. They can also grow acro frags at 6 to 8 inches of depth before they go under the 14K or 6500K. I am happy for the cost.
I compare these, and the cheap MH bulbs, to people that are brand snobs with cars. My new Genesis G90 is every bit as good as my previous BMW 750s were.. in some ways way better, and in some ways not so good, but overall, they are nearly identical cars in aggregate... but once some people find out where it was made and how much cheaper it was (not a lot, but still some), the cannot wait to hate on it when they have never gotten into it.
GE makes 6500K, not actnic bulbs. The 6500k would pair well with some actinics. If you are worried about these cheap bulbs providing enough PAR and spectrum, even though there is really no evidence, then the GE 6500k can fill this void being a very nice bulb for output and spectrum... it is just a bit yellow and most people like some actinics to balance it. They are cheap bulbs, but perform like expensive ones.

Come to think of it , that GE would look smokin with a couple b+ and p.
From the looking I did , Hamilton odysessa a couple others, were all the bunk to middlin to decent cf t5 and MH coming out of Asia from a hand full of manufacturers. Prettt much threw together what parts they could source at the t time and put whatever name was on the invoice cuz they bought rights to the patent to make em.
Pretty much the same buisness model of led B.B. now.
