before you purchase this product I would like to point out that the life has not exceeded 3 1/2 months due to the durable overheating in the reflector in my case. This corresponds to a daily 10h burning time just 1000h.
There is also a version with integrated reflector apparently not from the most suitable material, as for example, the switch could no longer be used after a few switching operations.
Conclusion In spite of the good price and the appropriate wavelength and light output of this product is not recommended.
Sincerely
