    i ordered a 50 watt version that easily reaches the claimed output at around 31 volts at around 1.65 amps with blindingly bright light, and even worked just fine at 3 amps(around 100watts) with massive heatsink. I am using it for a custom flashlight..

    I ordered 4 parts of the 50 watt version of this lamp. Delevery time was 25 days which which is quite normal. 3 part has CSUNDA marked on the top, one part was from an other maker. The lens of this COB leds are not made of glass as mentioned in the description. They are also not very well centered on the chip- see picture. All parts are working O.K. for me ...

    Olá, produto chegou muito rápido mas infelizmente não enviaram a cor correta! e não foi enviado a lente. Independente da falha de envio gostei de comprar no site..

    50W COB lens is not GLASS, but Silicone. SOLDER PADS are COATED with SOLDER MASK and was VERY HARD TO SOLDER to. Had to SCRAPE pad for a very long time with small screwdriver to CAREFULLY remove this coating and get down to some pad which solder will stick to. MAke sure you wiggle your solder joint after it has cooled. Several joints popped off and I had to re-scrape pad over and over in order to get solder joint to actually work. Watch out.

    Ordered the 50 Watt version , just received. The lens on this COB led in NOT glass however an very clear silicon based plastic. Also stands out it's small size (28x28 mm) for a 50 Watt COB led. For sure it should and will be mounted on a capable heatsink. Will test this chip the coming time. Delivery time better than predicticted ! Looks good, thnks Banggood
