Description
Assembled LED light Bar – Use to add more light bars to your Growcraft DIY light.
These are B-Grade LED light bars. They have varying cosmetic imperfections that may include, discoloration, dents, left over residue. These boards function and operate normally. The imperfections are cosmetic only.
Water Protection: Currently, the Growcraft has no protective coating against direct moisture exposure. If moisture accumulates near the LEDs damage may occur. Make sure to point any sprays downward and away from the LEDs.
Use of VOC (Volatile Organic Compounds): DO NOT USE VOCs, like burning sulfur, near any Growcraft. This can damage the LEDs beyond repair and is NOT covered by our warranty.
Parts included in assembly:
1 x Growcraft 40in Heatsink
1 x Growcraft 40in LED Board
4 x M3-6mm Plastite Screws (Installed)
Note: Only 4 center PCB screws are installed. Ends holes on both sides of bar are left without screws, those holes are used to install the PCB Cover after Light Bar is secured into U Frame Structure.

Well I spent a good 20 minutes staring at these and I dont know who does their quality control but they got better eyes than mine. Spotless bars. As a home cultivator I am once again blown away at how great this company is. Upgraded two x5 600 watts to x6’s. Outstanding!

I am a huge fan of these B-grade light bars. I started with a regular light bar and was really happy with my purchase. After waiting for these to come back in stock I was finally able to get my hands on 3 of these. As the other comments say, there are no noticeable dents and the lightbars are all completely functional. The B-grade lightbars are a great way to save a couple of bucks and still get the high quality ChilLED offers.
Another great part about ChilLED is the customer support. I wanted to try out a Veg bar but didn’t see the option on the light. After reaching out to customer support, they were able to get me squared away without a problem!
Again, really happy with these B-grade light bars and the ChilLED customer support. Highly recommend going with the B-grade if you’re DIYing and want to save a couple of bucks on some very high quality lights!

I ordered 2 of these “B” grade Growcrafts. As expected, they are flawless. You have to really knit-pick to find the scuff. Nice light output paired with 4 chilled logic pucks. Worth every $.

Would it be more cost effective to upgrade my current light or just buy another? My light if upgraded would need two new bars to make it wider to make room for more lighting boards. Then there’s the cost of the light boards and then the driver.I’m running an X3-500 whats after that?

Amazing quality, no idea where my defect is as my bars looks spotless.

When it showed up I had a hard time finding and dings or marks that would make this “ b” grade. When I did find the mark it was small and I would have easily assumed it happened during shipping.
