<span class="link_user">@XiceX</span>,no me I'm about 55cm in super lumens mode (660w) hps no problem, it all depends on the temperature I have an air conditioner so if you have a temperature that does not exceed 28 it's good but your lamps are far away in everything cases approach a minimum of 60-65 cm
