PROS
- Cheap - Very bright - Waterproof - Flexible - Great for DIY light bars & surface mounting
CONS
- Aluminum outer housing is just garbage - Only using 250-300mA or 4-5 Watts each @12.6v - Need 16v for full brightness, 1A 16W max each - Must be mounted to metal surface to prevent overheating - Supplied wire leads could be better quality
Considering how cheap these are, I can fully excuse the fact that the flimsy little aluminum sheet cover housings these come with are complete garbage and must be immediately taken off and discarded before installing. The wire leads supplied should also be unsoldered from the PCB and replaced with a thicker gauge automotive rated wire before installation if you want them to work most efficiently and not fail prematurely. I would have given them a full rating on build quality if it were not for these minor shortcomings but it did not affect the quality of the finished installation that I had intended for them. The actual COB LED arrays and the PCB units themselves are actually much higher quality than I expected for this price! The COB array on the PCB has a slightly raised bezel (about 2mm)and is back filled with a phosphorus bearing silicone gel that helps diffuse the light sources and balance the color temperature across the whole bar, giving a bright pure ice white consistent with the stated 6-6.5k color temp. The PCB is printed on a 2mm sheet aluminum substrate for better heat dissipation than a standard fiberglass substrate can deliver, making these able to run at full power with no additional heat sinking needed if directly surface mounted to a metal body panel or other metal surface (don't bother trying to use the 2-sided foam tape included). For my application they were installed as body mounted reverse lamps in my vehicle. They ran for over 20 minutes and were barely warm to the touch but got uncomfortably hot running unmounted on my test bench after only 2 minutes. The top side of the PCBs is also paint sealed to prevent corrosion. The only thing I needed to do for waterproofing was to paint over the power terminals, leads and exposed test points with clear nail polish to seal any exposed metal once they were resoldered with better quality power wires. I used Vigor binary jewelers epoxy to surface mount them after roughing up the back of the aluminum. It sets in 5 minutes, cures in 24hrs and dries completely clear and will bond effectively to bare metal as well as painted surfaces free of water, oils and wax. The white paint on the PCB also closely matches my paint, making them blend right in with the body color and placed so the leads can tuck away between a body panel crease to avoid spoiling the clean look. All in all I am very happy with these and I have just ordered a few more sets to use in another project making a custom light bar system for offroad use and because a few of my friends are now very interested in them after seeing them running on my truck. ;-)

PROS
Nice spectrum, clean ice white glow, cheap price, needs no modification to work, brighter than stock incandescent bulb. Would buy again.
CONS
Could have wider light angle, could be soldered better for more strength/reliability.
I figured on these as good dome lamp replacements in my GM and .... yep, they are. These are brighter than my stock lamps and they cast a very bright and appealing ice/moon white glow. No more depressing orange incandescent interior lighting for me! :D As usual, anything this price is made fairly cheap though, and I immediately saw room for improvement. Simply soldering both sides of the PCB to the electrodes would have resulted in a better build quality. I don't think I will have any problems with them despite being a bit more flimsy than I expected. The light emission is a bit too directional to be ideal but once the diffuser lens is back on the dome light it doesn't seem to matter too much.

PROS
Good color rendering with the 3000K-3200K modules, high emitter density, modules have mounting holes, throughput power bus, good emitter response linearity
CONS
Nothing really
These are some of the best quality 12v COB LED modules i have found on FastTech so far. Many of the cheap modules only have cool white and are of inferior quality and have bad emitters or poor linearity where some emitters are brighter or dimmer than others. All of these FandyFire modules i have purchased so far i would be confident to install in to any custom automotive lighting project. All the emitters light up evenly with no flicker and make for a very solid light effect with no diffuser necessary. They get hot at typical alternator voltages so a current limitting or voltage regulator should be used and mounting them on a flat metal surface is recommended. The mounting holes make it a simple job to securely install and the gold plated contacts solder perfectly. Very easy to completely waterproof once wired in. Good thick aluminum substrate as well, none of that flimsy foil thin stuff here. Worth every dime if you want reliable quality LED light on a 12v system.

Good for the price
CONS
The edges are a bit rough on some
Good and cheap. The mounting surface is perfect but the edges are a bit rough on some of them and may need a bit of fine finishing. Looks like they were packed right after being cut on a die shear press from sheet stock. Would buy again for the price alone.

PROS
-Thick tough crystal clear polycarbonate body -Glow in the dark silicone seal -Open cell foam pads included -Tight metal pin hinges
CONS
-No indexing guides for batteries
I'm pretty impressed with the build quality for the price. It feels nice and solid and tight and the glow in the dark seal was a nice touch.
