## Description

Review: Excellent LED bulb with impressive CRI to deliver good quality light. - These bulbs are high quality and very bright, with an impressive CRI that delivers excellent light quality. Bulbs with poor CRI tend to produce unfocused light and do not allow objects to reflect their true colors, which is not the case here. The neutral white option still feels quite cool, though it is certainly not the harsh blue tint typically associated with 6000K lighting. Given the amount of light these bulbs produce, the warm white version may be more suitable for general home use. That said, the neutral white works very well in my new open-plan kitchen and complements its modern look. I cannot comment on lifespan yet, but desertcart’s after-sales service is generally good from my experience.
Review: Great quality and very bright! - These lights are very bright at maximum, they dim very easily and smoothly, without flickering (as some from different companies have in the past) I can’t really comment on the durability as I have only just received them. They do the job perfectly and were a decent price too.

### ⭐⭐⭐⭐ Very (too?) bright white
*by S***D on 6 January 2026*

These bulbs are incredibly bright, very white and if anything far more on the cooler tone on appearance than I'd expect from a 'neutral white' light. Great if you want something clinical, not so great for home use.
