JAYNLT Y-5200W Solar Street Lights Outdoor,520000LM 6500K Commercial Parking Lot Lights Dusk to Dawn, Waterproof Solar Security Flood Lamps with Motion Sensor and Remote for Yard, Garage, Driveway

I've had this Solar powered Street Light over two weeks now and the performance is amazing. I've installed it in my back yard on a 15ft pole. At night it lights up half of the back yard at 30%. When it senses motion it comes on at 100% and really brightens up the yard. I will definitely purchase another unit fir the other side of the back yard. Yes, there are cheaper units out there, but if you want quality and performance, you will not be disappointed with this product. I would strongly recommend this product!

Update: customer service with the company does take care of you if you’re not completely satisfied. Sure it’s heavy and big and decently bright but the description of 520,000 lm is exaggerated by probably 100x. If you had 4 of these you’d have decent lighting for a half court basketball game. 1) “5200 watts” is essentially impossible here A 25”×12” solar panel has ~0.19 m² of area. Even in strong sun, panels produce roughly 150–220 W per m² (ballpark, depending on efficiency and conditions). That puts your panel in the neighborhood of: • ~30–45 watts in full sun (maybe a bit higher if it’s unusually efficient) So 5200 W would require something like hundreds of times more panel area (and much bigger wiring/heat sinking). Also, if it truly drove 5200 W at night, it would get extremely hot. 2) The “32,000 mAh battery” number is misleading without voltage Battery capacity must be in watt-hours (Wh) to mean anything: • Wh = (mAh ÷ 1000) × Volts Most of these lights use battery packs around 3.2V (LiFePO₄) or 3.7V (Li-ion). If it’s 32,000 mAh at: • 3.7V → 32 Ah × 3.7V ≈ 118 Wh • 3.2V → 32 Ah × 3.2V ≈ 102 Wh That’s the energy you have for the whole night. Now sanity-check with the claimed 5200 W: • Runtime at 5200 W from ~110 Wh = 110 / 5200 = 0.021 hours ≈ 1.3 minutes So if it were truly 5200 W, it would go dark in about a minute (plus it would be blinding and scorching hot). 3) What output is actually plausible from that battery If it needs to run, say, 10 hours overnight, and you have ~110 Wh: • Average power available ≈ 110 Wh / 10 h = 11 W (before losses) Even if the LEDs + driver were very efficient (they aren’t perfect), 11 W corresponds to roughly: • ~1,000–1,800 lumens (assuming ~90–160 lm/W at the LED level, less after optics/losses) If it runs fewer hours at higher brightness early on, you might see higher “peak” output briefly, but you’re still nowhere near 500,000 lumens. 4) “320 LED beads” doesn’t mean huge lumens Many “beads” are small 2835/5730-style chips. A realistic average might be 0.1–0.2 W per chip in a cost-focused product, and they often drive them below max to manage heat. So: • 320 chips × 0.1 W ≈ 32 W electrical (plausible peak) • 32 W × ~100–140 lm/W → ~3,200–4,500 lumens (rough, optimistic) That’s a believable range for a bright solar flood/street-style light. Likelihood it’s 520,000 lumens Effectively zero. To hit 520,000 lumens you’d need on the order of 3,000–5,000 watts of LED power (depending on LED efficacy), which the panel and battery specs cannot supply. How to test it (best practical method) Lux meter test (cheap and surprisingly solid) Buy a basic lux meter. 1. Mount the light at a fixed height (e.g., 3 m / 10 ft). 2. At night, measure lux at ground level: • directly under the light • and at several points outward (to map the lit area) 3. Estimate lumens by summing lux over area (simple version): • Find the area where light is reasonably “useful” (say where it’s ≥10 lux). • Compute: lumens ≈ average lux × area (m²) Example: • If you average 50 lux over 60 m², that’s ~3,000 lumens. If it were 520,000 lumens, you’d see extremely high lux over a huge area (it would look like daytime in a wide zone).

Since I installed the 8000W Solar Street Lights in my backyard I have been surprisingly impressed by the exceptionally bright daylight illumination. Installation was straightforward, with a sturdy mounting bracket and clear instructions. The solar panel charges efficiently even on cloudy days, and the battery easily lasts through the night. What I liked the most is the motion sensor and dusk-to-dawn capability. The light automatically turns on at sunset and off at sunrise, while the motion sensor boosts brightness when it detects movement. This not only saves energy but also enhances security in my backyard. The remote control makes it convenient to adjust brightness levels and modes without needing to climb up or reset manually. In terms of build quality, the fixture feels durable and weather-resistant. Overall, the 8000W Solar Street Lights are a highly efficient, cost-effective, and durable solution for backyard lighting.

Bought this because I have no Light since the passing of Hurricane Melissa, installed it less than a day now placed it in the dusk to dawn mode and it lasted all night which is a good thing, looks great it is also very bright satisfied so far just hoping it last will give update as time passes. Gave it 4 stars because its early days still.

Works great Great value

Very poor quality Only illuminates in the night for 3 or 4 hours after that nothing. I am very disappointed about this product

Love them! They put out so much light for being solar and I purchased during the winter months , only thing I did not know they did not come with a pole and had to order separately. We used for play ground area and sports court .

Love my light, couldn't ask for more!

This solar street light is amazing! 🌟 It’s super bright and lights up a huge area, perfect for my backyard. I love the remote control and different light modes—it’s so easy to use! It even works in rain or cold weather. The best part is No electric bill! ☀️ It charges during the day and lasts all night. Super easy to install too.

really really bright, easy to assemble and connect. the quality of the lights and even the supporting accessories is really high. overall, really good value for money. it comes with everything you need to assemble and even comes with a remote to operate so ease of use and assembly is really good

Finalmente un ottimo lampione solare

明るくて良い

Nous avons installé la lampe solaire dans le nord du Québec au chalet à des températures très basses(-30 degré)durant 10 jours de congé et elle éclaire très bien et elle a fonctionnée malgré le froid . La manette est très pratique aussi pour éviter de sortir dehors. Nous pourrons parler de son efficacité avec le temps. Jusqu’à présent nous sommes satisfaits de notre achat
