12,000 Kelvin - A vibrant and intense blue light - Mimics the illumination found in tropical rivers and lakes. Thanks to its well-balanced spectrum, sera Blue sky can be utilized on its own or paired with sera Deep sea as a lighting solution for marine aquariums. When combined with SERA Tropic Sun, it creates the ideal lighting for freshwater aquariums. Effective aquarium lighting is essential not only for fish but also for any live plants thriving in your aquarium. Plants require light for photosynthesis, which allows them to create food from carbon dioxide and water. For instance, tropical plants necessitate 12 hours of light each day, while plants from cooler waters need lighting that changes with the seasons. IMPORTANT: The lifespan of aquarium lamps is 12 months. The lamp's spectrum gradually shifts, and after this period, it will no longer serve effectively as an aquarium light for its intended purpose. To achieve optimal results, it is recommended to replace aquarium lights every 12 months. In essence, watts indicate the energy consumption of a light, lumens measure its brightness, and Kelvins define the color of the light.Shipping Notes

Not what I’d hoped
Color: Multicolor a (5-pack), Size: Small
The fabric is nice, soft without being overly bulky. The design was almost what I wanted. I’ve been trying to find underwear that won’t ride up and is comfortable to wear under leggings. The fabric has a LOT of stretch around the legs and deforms quickly. Then it rides up and wrinkles. Smaller leg openings might make the difference.

Great & Comfortable
Color: Multicolor B (5-pack), Size: X-Large, Color: Multicolor B (5-pack), Size: X-Large
I have bought 2 packs of this underwear. I love wearing them. They are very comfortable, and the size fits perfectly. I like most of the colors. The Bamboo Cool lettering on the front does come off after washing though. Otherwise the underwear has been great to wear.

Better than woxer imo
Color: Multicolor B (5-pack), Size: Large
I've been buying Woxers, but theyre super expensive for what youre getting. These are similar in feel and style so i switched over. Another nice thing is i dont have to deal with wedgies like i do with the woxers.
Theyre not perfect for wearing when its hot, youre still gunna sweat and these dont wick away sweat super well. But i havent seen many brands that do, and these are not the worst.
Im 5'7" and 145lbs and these are comfy and tight enough but not snug. They still leave a bit of indentation on the love handles. You CAN tell that youre wearing them under pant if they are tight.

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.

Well made, light fabric. Waist doesn't roll.
These bamboo underwear really do keep you cool.
They fit true to size, and wear easily. the wide elastic waist band doesn't roll on me.
They are comfortable to wear, washed and dried easily.
The material has some stretch to it, but not a lot.
Well made, no stray strings. Perfect fit for me.
Just what I was looking for.
