Review on Yescom Ultra Thin Incandescent Equivalent Downlight by Aravind Joshi

This is a product I want to add the saying "I want you to like it" because. i want you to like it In several of my other reviews, I've found that "final cost" or "final price" ultimately plays a HUGE role in the decision-making process. $35 for a set of 4 seems like a good deal and if it's a decent product I'd say so. I recently ordered some 2x4" T-Bar LED panels and they are AMAZING so I'm comparing them to these lights. .This panel is said to emit around 8200 lumens. That's a lot because it lights up my entire work area. These round out Lights are rated at 1400 lumens which means I need about 6 of these round lights, I connected 1 just to see how much light comes out (in a 7ft by 7ft bathroom) and it seemed quite to be dim. I know that an old school 100w incandescent bulb should easily light up a bathroom this size. A 100w incandescent bulb puts out about 1200 lumens so a round fixture like this should suffice. Well I guess that all 4 bulbs (5600 lumens total) would be required to match a 100 watt bulb In summary, a pack of 4 100 watt bulbs (1200 lumens) costs about $5, with one bulb for a 7 x 7 feet tall s bathroom that would need 4 of these 1400 lumen LEDs to illuminate the same room ($35). The color is terrible, but I am guilty of the charge. I was stunned by the low price and couldn't make out the color temperature of 6000k-6900k. For normal use it should be somewhere between 4500k-5000k otherwise everything turns blue. Therefore I cannot use these lamps. Why is my rating so high? Well, this product is easy to install. Haven't installed anything yet, but it's as simple as figuring out where you want to mount it using an 8" hole saw, plugging in the power and using the clamps and you're good to go. I give this product high marks for its mechanical design. I mention the mechanical design because the electrical design is very poor. Not just bad, but very bad. I'm the kind of person who likes to open things up to see. However, the chart in the product photos is pretty accurate, but I did it. Measure the voltage the transformer is outputting and it reads around 79 VDC. The transformer shows 40-60VDC. That is a difference of almost 20 V DC. A lot of things, especially LEDs, are very intolerant of voltages of +2V or more, let alone 20V. So I found that all LEDs are connected in series, which is possible for high voltages, but knowing how LEDs (diodes ) work, when an LED lights up, it either burns out completely and the circuit opens, the light goes out. When one LED burns out but burns out, the voltage on the remaining LEDs increases and you see effects like dark spots (where the burnt LED is located), the light gets brighter or flickers due to the increase in voltage, but complete failure soon follows or there will be a chain reaction. Having opened one, I cannot return the product, but I may be able to refurbish it for safer performance and longer life. I'm impressed with the mechanical construction but very disappointed with the electrical construction. Nowadays there is some enthusiasm for LEDs from China, which use a color temperature of 6000-6900K, which is terrible for the eyes. Have you ever thought that today there are new products like "Blue Light Goggles"? Stick to a color temperature of 4000k-5900k and maybe the 'thinnest' light isn't a good idea. This limits the ability to connect all the LEDs. In any case, don't let the low price get you down. Research, research, research. You'll probably pay more, but you'll probably be disappointed if you have to buy and install LOTS of these before realizing you need SPF 1000 sunscreen and sunglasses when you turn on the lights.
