I have 50 to 100 of each with much more I can get. The 18 and 42w lamps are 2700k and the 26w is 4100k. They are maxlite brand and I have them listed on eBay right now as well. Interested in trades for sodium anything, especially SOX of course. Interested in two 50w hps tallpacks also. Will figure out how to ship internationally if necessary. Will also consider selling lamps outright as well for $3 ea. plus shipping (will try to find the best rate possible). Quantity discounts will be considered. Thanks!!
