I have a bunch of old hydrogalaxy LED lights that I started with...I still use them for vegging sometimes, and they all still work great, and run cool. They changed their name, but are still out there! I'm currently running a MH Hortilux blue for veg, but only because my plants are sickly and i thought it might help them. But it would be way too hot for a small tent I think.
Which leads to another tip. Keep things clean, remove all dead foliage, always disinfect your grow containers after every use, and keep good ventilation in the tent....All very important things, or you can wind up with sick plants like me! An ounce of prevention is worth a pound of buds!!
