If you are looking for a specific lamp for the flowering stage, the Philips SON-T-PRO 1000w lamp will surprise you with both efficiency and effectiveness.
This bulb provides a reddish/orange light very similar to that of the sun in the last stages of summer, so the plant will speed up all the processes, as it feels that winter is near.
Obviously, if you choose the Philips SON-T-PRO you will need another bulb specifically for the vegetative phase, because with one that emits such orange light plants will tend to glean too much.
The bulb has a lifespan of 4 crops, I do not recommend more uses, as it usually loses efficiency due to wear and tear although light consumption stays the same. You can grow in a space of up to 9.8 3x3ft (3 m2) with a good reflector and of course you should install a 1000w ballast.
