Projection Size (Projection Distance): 61 inches to 230 inches (at 0 cm to 90 cm) Purchased after internal cleaning and replacement of consumable chips, and only tested for about 30 minutes. (This product is less likely to have issues like dead pixels that are common with DLP projectors immediately after purchase.) The LED lamp usage time cannot be confirmed through settings, so it is unknown. I have switched to Aladdin, so I haven't used it other than to check its operation after purchase. Regarding the image quality, I only checked it by projecting onto a textured wallpaper since I don't have a screen. (I do not guarantee a clear image.) Since the chip has been replaced with a new one, there were no dead pixels. Accessories: AC adapter Remote control (with batteries for operation check) Mouse (rubber part is deteriorated) Mouse pad Instruction manual (probably a copy) Regarding the image, since I haven't projected onto a screen, there may be subtle color differences. Although it has been cleaned, there may be some remaining dirt.
