    Default Havis Shields HID - some pics/beamshot

    Just had a few minutes to play with this...

    These were taken in a garage in bright sunlight, I had to crank back the exposure to put it into perspective, which is why it looks like night!!






    Enjoy...

    P.S. The humble little yellow glow to the right of the HS HID is an MN20 (250 lumen) lamp in an M3T running fresh batteries...

    Distance to the wall is about 8ft...

    Thanks for the pics symes. I hate to say it, but that strap/clamp with the raised nut and bolt looks really hokey. I'd really like to get a look at the back end of the HS, including the switch. What is the switch like on this light?

    You're right the bolt does look a little 'hokey', but given the large lump of, what I assume to be, glass that has to be held in place and be watertight, I think its probably a good solution. The rest of the unit is entirely thick rubber and appears to be sealed. I see no way into the unit without taking the glass out. The retention ring is at least partly sunk into the rubber housing.

    The manual says "contains no user serviceable parts" - this appears to include the lamp assembly.

    The switch is small push on/off button on the side of the body which is rubber covered again for water resistance. I imagine that it is intended to be able to be operated in a pair of fire gloves. It requires a lot of pressure to engage and disengage, and if you didn't hear the ballast kick in, you wouldn't really know you had it on, but consequently, it isn't likely to change status if it got knocked over on a rescue scene etc...

    With the right portable power source, bag batteries, bottle batteries etc... it makes a perfect S&R light. I tried it quickly the other morning and the beam penetrated about 300 ft into the trees behind our house where new home construction is going on. The spot still seemed brighter than heck even at that distance. Makes me ALMOST wish that I could switch the reflector to a SF style one that would shorten the throw but increase the flood - there is way enough light here to do that...

    Interestingly, after being bright white the first few times turned on, I noticed that the beam had a small yellow tint to one part. On turning it off, there appeared to be small yellow liquid in the discharge area of the lamp. Now it seems to be variable whether it shows or not, but this reminded me of some recent fun and games with the X990.

    Have fun,

    Simon

    Thanks for the beamshots but would you mind resizing these a bit for those with small monitors or low resolution graphic cards? [img]/ubbthreads/images/graemlins/wink.gif[/img]

    symes, do you think you could get some outside beamshots compared to another light??? Anything would be really great. Thanx [img]/ubbthreads/images/graemlins/wink2.gif[/img]

    I'll try and get some night pics compared to a few like

    Cheap 2MCP 12V spot, Surefire M6/500, Tigerlight

    Right now, I've just been running it with the car 12V output....my goal is to use it on my boat so I'll have all the 12V I need.

    The SLAs are ok but heavy. I have some exit sign 6Ah SLAs that I use for power outages etc... and could bag up those. However, for portable use, I'd probably rather go with one of the cycling bottle Li-ion type deals - weight is the big thing it seems.

    There are a bunch of rescue built 12V belt bag supplies though I know, that some fire guys have available - might check those out.

    the yellow in the beam is normal

    my hid thor has the slice of yellow on the bottom of its beam.

    my hid vector has the slice of yellow on the top-the reflector it inverts the beam

    Just the salts in the bulb......

    I was also thinking about using a bottled li-ion pack, but their is no direct 12 accessory adapter on those and I don't feel like doing a wire-strip-connection hack job on it. I just want to plug it in and go. [img]/ubbthreads/images/graemlins/smile.gif[/img]

    what is the min and max operating voltage ?

    how much current does it draw at 13 volts ?

    does it take long to warm up ?

    I do not think the metal hoop is bad lookin.

    can you rotate the part that sticks up towards the bottom of the light >
    a lith ion pack would be kool.

    you could use a fanny pack or a money belt

    to make a nimh c cell pack for it.

    I use 12 cells in my hid vector

    battery voltage sag and other voltage drops probably keep battery pack voltage under 16 volts.

    and I do not rapid charge the battery pack so voltage per cell at end of charge is 1.38 volts.

    I was thinking of going the NiMH route myself. The Hallis website claims a 3 amp draw at 12 volts.

    Markdi,

    Your using 12 C Nimh rechargables? How do they perform and how is the runtime?

    I was told that it drew 3.5 to 4 amps [img]/ubbthreads/images/graemlins/thinking.gif[/img], and I was told that by you, markdi, or Battery Charger.

    yes it draws around 3.5 to 4 amps but I was wondering if
    any one had a more precise current draw value.

    I have not done a runtime test on my vector hid

    I have ran it for over an hour.

    It should run at least 70 80 minutes or so

    What do you think the runtime for the HS would be if it was hooked up to Phaserburn's $29 12v 6Ah? anyone?

    Thanx [img]/ubbthreads/images/graemlins/happy14.gif[/img] That's long enough to keep me happy I suppose. But, what do you think the runtime would using a battery that is 3 amps with everything else the same?

    it depends on the capacity internal cell resistance of the battery in question.

    smaller batterys usually have more internal cell resistance.
    so for a given current draw level you loose more energy internally in the battery as heat.


    my hid thor at 35 watts runs for around 1 hour 30 minutes
    with the original 7 amp sla

    my hid vector with a 3 amp sla runs about 20 minutes.

    nimh is much better - lower internal cell resistance

    lion batterys even better

    OK More pictures....

    This time in the basement, (still haven't got out after dark yet...), with some but not much ambient light. (Exposure fixed at 1/45s F2.8 ~100mm, distance 30ft. Again, this exposure makes the Tiger and M6 look a little dim compared to the overall eye effect at the time, but serves to show just how bright the high power lights are in practice.

    We have, a Vector 2MCP 12V spot (fresh charge), Havis Shields 35W HID (powered from 6Ah SLA Exit sign batteries, UK LC100 HID (fresh Duracells), Tigerlight (Fresh charge), SF M6 (about 2 mins on the batteries).

    Vector


    Havis Shields (allowing 30 sec warm up and stabilisation)


    UK LC100 HID


    Tigerlight


    Surefire M6


    And another of the Havis Shields after about 2 mins runtime - seems a little brighter still


    Enjoy,

    Simon

    so is tha havis twice as bright as the vector ?

    11 to 12 of these would make a nice small-light battery pack.

    http://www.onlybatteries.com/showite...temID=12386.25

    11 of them would probably run the havis shield for about an hour.
    50.16 watts

    voltage sag under load(including the cord to the havis)
    might make 12 cells possible. 54.72 watts

    Nice Shots symes!!! [img]/ubbthreads/images/graemlins/happy14.gif[/img] I thought my Light Cannon was bright [img]/ubbthreads/images/graemlins/rolleyes.gif[/img]!

    Now, if Jeff shipped my HS around December 29 or 30, I am guessing it should be here within the next two days if it shipped through USPS. I can't wait!!

    C ya,
