DO NOT BUY THEIR GARBAGE - I HAD THE WORST EXPERIENCE OF MY LIFE WITH THESE GUYS.
THEY SPECIFICATIONS ARE FALSIFIED.
THE BAR DRIVER IS FAULTY AND 2/3 of MY LIGHT GOES ON/OFF RANDOMLY
Quantum Board Led Grow Light 9bars+2pcs uv
HERES THE ADVERTISEMENT:
This product is no longer available.
www.alibaba.com
they offered me 2% refund only. and refused to discuss anything further.
I then asked to return the light to china, they refused the offer.
I deserve to return the light to the company or discuss a reasonable settlement, but they wouldnt do anything. i ended up using alibaba trade assurance and they screwed me over too. made me wait 2 months for resolution and i eventually just called my credit card company and disputed the chart for 100%.
This unit is defect is not usable it is garbage and not functioning.
1. Ppfd performance is way off by 50%-Your fake the test results they claimed 2100 PPFD at 12'' ( i cant measure anymore then 1200) to be completely honest. i posted teh ppfd chart for the 8 bar model, and mine is 9 bars and still not even 50%.
2. The uv bars are not sealed correctly - SEAL IS BROKE AND NOT COMPRESSED
3. The uv bar is too long due to faulty screw and low quality construction they do not fit- so now useless
4. The frame has mis placed screws, which doesnt allow to install UV bar- bars are loose and falling off
5. The dimmer dial is broken - sent broker dial
6.the temperature of the unit runs 10 Deg C higher then specified. they claim no more then 51 deg C. it is 60 deg c.
8. 2/3 of the bars keep shutting down and turn on/off randomly. faulty LED DRIVER or short circuit
TOTAL GARBAGE
FOR ALL THE REASON ABOVE; I REQUESTED A FULL REFUND
