<div>Alan,</div><div id="yui_3_16_0_ym19_1_1504906585377_9882">No, I got it right, 48,000 lumen for the pair and there are also 96,000 Lumen per pair. Now thats' bright;-) I am not sure how they will work but for the 10 minutes it took to put bulbs in my fixtures, it is worth a try. I do NOT want to rely on one light source. Imagine you drive 4 hr to the dive location then 1 hr to get on site then you dive 380 feet to the wreck and you spot the gold and your light quits. At 380 feet it is dark! I currently have three separate light sources with separate power sources and separate switches. </div><div>Hank</div><div id="yui_3_16_0_ym19_1_1504906585377_9896"><br clear="none"></div>
