<div dir="ltr"><div>Jon on the R300, I am using four 5K lumen Bridgelux Vero-18 lights for a total of 20K lumens. Each light is packaged in a 1 atm enclosure. The LED driver on each is a Lightline REC-24-1.20, which in connection to the array pulls 1200mA at 30V and 36W power. The driver is mounted on a custom PCB that gives polarity and overcurrent protection. Even though the driver is dimmable, I use them at full power. These LEDs pull so little current that I am thinking on adding two more.</div><div><br></div><div>I am with Hank, the more light the better.</div><div><br></div><div>Cliff</div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Aug 27, 2017 at 9:29 PM, Jon Wallace via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br>
While we're in the middle of an LED investigation, can those of you actively diving with LED lighting give us a guideline on a range of lumens we should be striving for (per lamp), how many lamps, spot or flood?<br>
<br>
I know Alec was using an oil-filled 3000 lumen lamp on SNOOPY before selling it. I've been looking at PRIMELUX 8100 lumen lamp that seems like it could be easily adapted for oil or air compensation. Generally I would say more light is better but also need to be careful about power consumption so I don't want to purchase more light than is necessary for general operations.<br>
