No cfl 3000k leds. I don't understand Tommy boys reference to the post by Waira it had to with ph and bloom booster. Maybe telling me that 3000k is better suited to bloom like a hps verses mh. I was trying to order online to avoid the 2 hour round trip to lowes or home depot it sets my leg on fire. Time to man up and do what I have to do. I should be able to find bulbs in the recommended 3500k to 4000k range for about $1.50 each while I'm there. Thanks to both of you for the quick and helpful replies.
