<div dir="ltr">Hi Jon,<div><br></div><div>I tried one side by side with a Trustfire just now and it's actually really hard to tell. Its just that the Trustfire is a pencil thin beam and the new ones are the exact opposite. That in itself should be an advantage for the new ones. In a pinch, I'd say they are about the same total output, but that's very very approximate. One thing I wonder about... the new lights have a very wide operating range of voltage, they work with anything from 12V to 48V. I'm running them on 12V and wonder whether higher voltage would equate to higher output. </div>
<div><br></div><div>To answer your other question, the mounting bracket is stainless. I'm thoroughly impressed by the build quality, they didn't skimp on these.</div><div><br></div><div><br></div><div>Best,</div><div>

How does the light of both compare to your eyes? They are both
listed at about the same lumen output. The Trustfire uses three
1000 lumen CREE led's whereas this floodlight uses sixteen 200 (or
so) lumen led's. I realize the trustfire is more of a spotlight
but just curious how they match up as perceived by your eyes in
terms of total light output.<br>

<div>Hi Alec,</div>
<div>Those lights on your link look good. Let us know how you get
on with your test next week, I and im sure others would be
interested to know how they perform.<br>
Thanks</div>

<div dir="ltr">I used Trustfire lights for a season on Snoopy
but the experience was all around bad. I bought two, one of
which did not work due to a faulty connection at the endcap
(which acts like a switch). The factory shipped me a new
end-cap that fixed the problem. In fresh water they worked
well, but when I went to Islamorada last year they lasted
less than a day in the salt water. After just hours, one
stopped working altogether and both lights were very visibly
corroded. Silly me, I hadn't thought this through. The
Trustfire lights close the circuit when you screw in the
endcap on the handle. They use the light body itself as a
conductor, like a car uses its chassis. I think the issue is
that if you put two such lights in salt water, you will get
stray currents between them.

<div>On next week's dive I'll be testing new lights, which
are LED flood lights intended for tractors or off road
vehicles. I've been really impressed with how solid these
are. They are wired with two cables, rather than using the
light body as a ground. Second, they have a little screw
that serves no visible purpose, but which when removed
allows you to fill them with mineral oil. It took a while
to get the last bubbles out, but with patience you can
fill these with oil and remove all bubbles in about an
hour. The front plastic has a little give to absorb the
compression if I have any bubbles left, but I think I have
none. To fill them I used a syringe with a "dispenser
needle" which is a blunt syringe needle you use for
filling things rather than giving someone an injection.
The lights are IP67, so supposedly water-tight, but my
only mod was to reinforce the cable gland with some epoxy.
We shall see how they work, but my hopes are up, I think
these might finally be the ideal sub lights and can be
used virtually off the shelf. I recommend not buying them
until Snoopy returns from next week's dive, but here is
the link if you want to take a look in the meantime.</div>
