For the white spectrum these bulbs perform very well and nice and bright and ever serve as zigbee repeaters for your zigbee mesh network. However when using the rgb color functions the 100% brightness level is severely dim compared to other higher end smart rgb bulbs. Personally if you want brighter colors and zigbee function I'd recommend the ikea tradfri rgb e27 bulbs even though they cost twice as much. However if you just need white spectrums most of the time and some dim rgb other times, these fit the bill well.
