I don't install lights commercially, not yet anyway, something I would definitely love to do someday. But right now, im looking for lights for my christmas tree this year. I would like to switch to all LED for safety and energy savings purposes. My tree is usually about 12' high, and 8-10' at the base. Last year iirc I used 6 sets of 25 bulb multi c9's, and 6 sets of mini white lights. I signed up with Holiday Light Source, I haven't decided yet if I want to go with the warm white, or pure white for the mini's. But im worried about the c9's. Every set ive seen (walmart, lowes) are very dim. Are there any commercial grade sets available that actually put off some light? Im not stuck on c9's either, c7's would work. Looks like HLS only has rectified left in the c9 multi. Can someone suggest some bright c7/9's or any other suggestions that might save me money and last a while. Thanks guys!
