Lumeri Bewertungen 

I'm very pleased with your products. For now everything is as you promissed. The prices are fair and delivery is fast and precissed. Thank you.

Shipment arrived quickly, the bulb works just fine. Good price, satisfied.

Great company with the best pricing on led lights. I had a question after purchasing my lights and they answered me on the weekend. I highly recommend them and will be purchasing additional equipment from them in the future.

Fast delivery. And all plants are turned to this light :) guess they like it. Only thing - i wished to have user manual. Thank you!

Solid, very nice industrial grade lamp. Ordered a second one soon after getting the first

Very fast delivery (05.04.evening I created order-09.04. 15:03 my lamps was in my flat, in Riga, in Latvia) and great products. My plants are greatfull.

Review based on experience with their grow lights.
So Lumeri seems decently good at it's price point, quality is where I expect it at the price they offer - good, could be better, but unless you want to play a lottery with similar lamps on aliexpress, I doubt in Europe you'd find same price~quality balance without special offers or discounts.
I'd give 4 stars since it's nothing exceptional for consumer level lamps (their more professional line up might be different), but adding one on top since customer service and overall how they treat customers seems to be top-notch, at least in my experience. One of lamps I ordered had a crack in diffusor, so they responded to me (during the weekend) straight away that they'll ship a replacement with no extra cost nor hassle for me. Within a relatively short time it was delivered and no issues found with the replacement one. CS person was nice and friendly.
TL;DR seems to be a good and genuine company, if they'll invest further in quality of the products and provide tad better (more exhausting) specifications for the lamps themselves - I'm pretty sure you won't be second-guessing whether to buy your grow lights from Lumeri.

I'm pleased with Lumeri. They had exactly what i needed, not overpriced at all.
It arrived safe&fast.
Regards.

Thank you Lumeri, I got finally my packet. Your work was professional and personal is helpful. Only problem was too long transportation, but there was two reasons: postnord have not own working filial in Estonia, thay are working together with Omniva and some information can miss (it happed) and second reason (I think) was corona virus.

The website is clear and has direct information. All the buying process was smooth and easy. I strongly recommend Lumeri.

Great price for the grow lights. Very fast shipping. The lights are great, simple to mount. I recommend!

Great quality product. Came with cables and informative booklet about the panel. Arrived within 2 weeks which is super fast. My plants love their new light.

Realy nice led lamps, fast shipping supper price.
