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.

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.

PROS
Pretty cheap, pretty sturdy
CONS
950 Lumen is more like 450
I'm not going to bash on this too much since my only real gripe here is that the 650LM LED lamp I already had installed was brighter than this supposed 950LM lamp I was going to replace it with. I'm sure I will be able to find some use for it eventually but it's no good for a reverse lamp on a vehicle with a tinted rear window, that's all I can say. Other than the obviously overstated brightness rating, it's actually a pretty tight little unit. Despite drawing less than the rated 5W when running on 12.4v, it does get fairly hot to the touch if it's been running for a while though so do be careful of that. Based on the feel and quality of the build it should stand up to use in automotive applications where the bulb lives inside a relatively well isolated assembly. I'm giving an overall rating of the product for the price a 4/5. Would have been a 5/5 if they didn't lie about the brightness by a factor of almost double. :/

PROS
cheap, takes 1-4x 18650 in parallel, batteries can be recharged in the unit, actual power off switch, built in flashlight, charge level indicator LEDs
CONS
Must remove 2 screws to change batteries. Case could be a bit tougher. Must remove cover to press the BMS reset switch which is not accessible from outside. Only one USB port. No instructions included.
Despite the quirks my original unit has, I actually just bought 3 more of these to give as gifts. It's actually a pretty decent USB power bank for pretty cheap but it is not without it's quirks. Buy this if what you want is a cheap power bank to charge your phone and run USB gadgets when you are off grid that you can feed 18650's to at will. It takes 1, 2, 3 or 4 in parallel so as long as all the batteries going in are at the same voltage, it should be fine. With high capacity batteries you can easily get 12 amp hours out of this thing before having to recharge or swap out batteries so that ought to charge your smartphone a few times while you're on the road or camping out. I like the actual toggle on/off power switch. You won't have to worry about the vampire load the circuitry draws leeching away your precious mAh's if you want to shelve it for a couple months, so many other USB power banks will self discharge after a few months because they never truly shut completely off. This is just good enough to rely on and just cheap enough to take in the bush and not be devastated if it gets trashed. Heck, you can buy two of these for the price of one single 18650 integrated charge stick from a retail store that will only give you one full phone charge if you're lucky, this one will give you five or more charges and always be ready to work when you need it.
