    LUMII 400W SUNBLASTER HPS GROW LAMP The 400w LUMii SunBlaster Auto HPS grow lamp could possibly be the perfect dual spectrum grow lamp. With increased output and an emphasis on the blue spectrum, they’ll encourage equal amounts of growth during the vegetative stage and bloom, meaning no need to change lamps for optimum flower production. The crystal glass used on the 400w LUMii SunBlaster has a constant thickness that allows the light to emit evenly. LUMii also avoided using a barium film which can darken or blacken the glass, giving reduced output, so with less gas impurities, the emitted light is a lot cleaner and more stable. Combined with an E40 mechanical double layer fitting, the SunBlaster has a lifespan of 32,000 hours and the output is as follows: 140 lumens per watt / 56000 lumens in total Now do the same for this.

Great quality
Color: Pink
Not the pretty pink that’s in the advertising photos they’re using, and my camera is always spot on with colors. Heavy and a great pot though!

A Must-Have for Home Cooking
Color: Red
This Dutch oven is excellent for everyday cooking. It’s solid, heavy duty, and heats evenly, making it perfect for stews, soups, roasts, and baked dishes. The 6QT size is ideal for family meals, and the lid fits tightly to lock in moisture and flavor, giving tender and delicious results every time. It works great in the oven or on the stovetop and holds heat really well for slow cooking. Overall, it’s a reliable, versatile, and affordable Dutch oven that performs like more expensive brands.

Great quality. Easy to clean. Nice appearance.
Color: Red, Size: 4.3-Quart
Solid, heavy pot for cooking and baking. I bought it mainly for making soups, stews and breads. I have only tried soups thus far. The pot cleaned up very easily. The bottom of the pot heated uniformly. Nothing was stuck to the pot when I was simmering on the glass top stove. I have not had the chance to bake yet, but seeing how evenly it held heat while cooking, I am thinking this will be perfect. I bought the red color. It gives a nice pop of color in my kitchen. This pot will probably last me a long time. I would buy one if I needed a replacement, or a gift for someone.
