SUNVIE 12W, 12V SET WITH CONNECTORS:
Best on Amazon. Guarantees AC/DC supply works, best LED COB Engine, best materials used, by far the brightest and the best waterproofing design. The included connectors are best in industry, I could not find any better design anywhere else even outside of Amazon. The connectors and lights together are awesome and nothing on Amazon comes close to them. They are multiple times brighter than others, thus, even if they have a slightly higher watt rating you may end up with a lower energy bill as they are so much brighter compared to the rest and you will need less of them. However, LEDs are so efficient that the difference would only be a couple of cents per year. Please see more details in my video. These lights and connectors will most properly last a long time and are a good investment.
ALEDECO 5W
Maybe second best on Amazon but lot of drawbacks. These have quite a good LED COB Light, but it is very small, most properly only about 25% of SUNVIE. They are much less bright, maybe half the brightness of SUNVIE. The materials used are ok, however, the waterproofing is sub-standard. The lens gasket is too less thick and the cable entry fitting has no gasket at all. I am worried about its water tightness and added silicone as additional sealing. The cable is extremely short, too short in my opinion. The connectors are totally worthless, added as advertisement gag for people who do not know better. But now the main problem. The product description says only rated for 12V DC. While those work on AC, the manufacturer will not warranty that as he clearly specifies DC power source. By far the most landscape transformers in the USA are AC. Thus, the life span on a standard US landscape transformer might be shortened and the warranty not granted. Please see more details in my video. If not additionally waterproofed with silicone, I do not see them working for a long time. AC/DC problematic may proof to be critical over time.
ZUCKEO 5W
These have similar body/material to ALEDECO but are worse. They say they are 5W but they are just 3.5W when measured. They are not bright at all and their LED Chip is the worst – seems outdated technology is used. The screw that connects the body to the spike is a Philips screw which really is the wrong type and brings nothing other than headaches during installation. Water tightness similar to ALEDECO, Lens sealing to thin, no gasket at the cable entrance fitting. I used GE silicone to waterproof them. It seems the company is not very honest with Lumen and watt output. The included connectors are worthless and an advertisement gag. Please see my video for more details. If not waterproofed with silicone these lights may not last very long. Update: After 6 weeks 2 of the lights have water drops on the lens. The seller explains that as long as they still work its fine to have water in the body and that I should not put them into area where sprinklers reach. Wow, almost as expected!
MEIKEE 7W
This company has developed a new design, basically replacing Aluminum and glass parts with cheap plastic. Glass lens replaced with cheap plastic lens. Aluminum spikes replaced with plastic spikes. Aluminum cap replaced with plastic cap. Worst, they advertise an IP66 rating but really have the lowest water proofing features of all of them. The cable entrance into the body is sealed with a rubber ring. The ring is not very tight to begin with and rubber/epdm will crack and age with sun exposure over time. I give these the lowest chance of long term durability because of the cheap non-durable materials used and the lowest water proofing potential even if they claim the highest IP66 rating (I am not sure what Chinese body authorized this rating and if the body has any reputation or if the manufacturer just self-claims this). Very disappointed about their trial to cheapen down the product in a new design after having received good reviews for the old design. Please see my video for more details. Update: First lights suffer water intrusion just after a couple of weeks of use, unfortunately almost as predicted...
