	Introduction to :HID & Xenon Portable Task, Search & Rescue Lights The HID & Halogen Type Flashlights sub-section of Personal Illumination Options is a collection of illumination products that span the vertical range of products that are typically used by specialists requiring high intensity illumination that is portable and yet that may shed light on subjects substantially further away than even the largest Police type flashlights are capable of illuminating. As such, they represent a narrow scope of products that share a common feature of using a High Intensity Discharge (HID) lamp or high wattage Halogen bulb, 9V-12V power sources and in some cases, rechargeable batteries. The evaluation criteria for this special class are similar to the general flashlight evaluation criteria but with the addition of discussion specifically aimed at rating real-world throw- since the ability of such lights to illuminate subjects at great distances away- makes them indispensible to workers as well as emergency responders.
	Description The Havis Shields-35W HID & 100W Halogen search lights are a sibling pair of hand-held searchlights that share the same reflector and 'chasis' but which are otherwise different products with differing power-trains and bulbs. These lights are both powered by 12V DC sources-the primary method being to connect the terminal Cigarette Lighter plug, into the socket of an automobile. Alternatively, a portable battery with a Female Cig socket connector may also be used for roaming use. Unlike the run of the mill handheld searchlights and lanterns, the HS35 & HS100 are totally enclosed in a heavy duty casing of hard rubber like material called Elastomer. This makes them industrial looking and lends to thier simple practicality. The HS35 uses a 35 HID lamp that only draws 3 Amps to put out 3,200 Lumens. In contrast, the HS100 uses a Halogen bulb that puts out 1,800 Lumens at 8.5 Amps. This in theory means that the HS35 is much more efficient. Even still, the HS100 has a unique property that gives it an edge for certain applications. Both products are intended to be used near a motor vehicle where they can illuminate a worksite or important target distances of between 200 and 400 meters. An accessory shoulder carried battery pack untethers these lights for convenient use away from a motor vehicle. ------------------ Sales Source:http://www.havis.com ------------------ Specifications Dimensions:L=8" ,H=6.5" Bezel Diameter=6" Net weight:HS100HAL(40oz) / HS35HID(48oz) Casing: Black Hard Rubber Elastomer Lens= Heat & shatter resistant Pyrex Bulb type: 35W HID Xenon & 100W Halogen Color Temperature: 35W HID (5,500ºK) / 100W Halogen (3,400ºK) Average Bulb Life Expectancy:35W HID(2,500Hrs) / 100W Halogen (50-100 Hrs) Power-12V DC Charge Time For NiCad BatteryPack=12 hrs for full charge DC, Input Requirements:12V Draw: 35W HID(3 Amps) / 100W Halogen (8 Amps) Run-time 35W HID Xenon (100Minutes) & 100W Halogen (35Minutes) Accessories: NiCad Battery Pack and Charger ------------------ ABOVE, Left , Handle \| Center,Detail of Pushbutton Click Switch Right, Detail of Retaining Ring Screw ABOVE, Shows various hand held positions ABOVE, Left, Attached to 12V NiMh Pack via an adapter Right, Detail of Female and Male Automotive Connectors ABOVE, Mobile Power Kit with Spotlight plus shoulder carry 12V DC NiCad powerpack and A/C Wall Adapter/Charger ABOVE, Note: HID bulb in center ABOVE, Left, Detail of 100W Halogen bulb ABOVE, Warning Label on 100W Halogen Light Evaluation Results & Summaries Ease of Use Excellent. The user simply locates and depresses the Click for On/Off switch button on the left side near the handle, to turn the light On and Off in a similar to many battery powered lanterns. Focus is fixed at the point of maximum spot. Charging the optional battery pack involves the insertion of male connector of the wall adapter into the female connector on the battery pack. Handling the light is easy thanks to an excellent mid point balance and a convenient 45º angled handle. The design of this pair of lights allows for at least three comfortable hand held positions in addition to two flat surface positions. Clamps and other attachment solutions may also be used to support the lights via their handle. There is no tripod bushing or other attachment connector. Because there is no way to change focus or brightness, these lights lack any superfluous controls- making their use self-evident enough for almost anyone to divine, without a manual or instructions. 5 points ------------------ Task performance optimization Throw-HS35HID = 12'Diameter Hotspot at 400 Meters (MDOI) Throw-HS100HAL= 6' Diameter Hotspot at 300 Meters (MDOI) Good. Both these lights throw a punchy combination beam at distances that far exceed what one might achieve using a Police type flashlight. For illuminating subjects at a great distance or located in very dark caverns or caves, these lights are effective. The Halogen is most effective at overcoming the 'washed out' colors that users tend to perceive when using a near daylight source in a context when the ambient illumination is dim or non-existent. In addition, the Amber/Straw hue produced by the HS HAL 100 is preferred for piercing haze, fog or smoke. In circumstances where an efficient, cool-running and long lived bulb are paramount, the HS HID 35 has the upper hand. Both lights benefit from the use of the accessory battery pack for applications that would preclude the use of an extension cable to connect the lights to an automobile's battery .A fully integrated set of lights that piggy-back onto a battery pack could be a welcome development for customers that would rather not deal with any cabling at all. 4.5 points ------------------ Documentation Quality Good. The instruction booklet is regionalized (English- as evaluated) . It's written and illustrated in precise, concise and professionally laid out step-by-step sections that enhance optimal information absorption and that minimize mistakes. Typographic font size is ideal and diagramming is highly professional. Being in 8.5"X11" format it's not very pocketable- only serviceable. 4.75 points ------------------ Balance, Grip-ability, Stow-ability, Tabletop Stand-ability Very Good. Though both these light use an identical casing, the HS HID 35 is heavier due to it's dependence on a Ballast. Nonetheless, they are both very easy to manage with bare or gloved hands. Wet or oily hands will welcome the 'grippy' rubber surface and perforations that run the length of the handle. Both lights prefer being perched on their bellies and pointed straight ahead, though flipping them over allows for a serviceable ( if precarious) 45º up angle- useful in changing a vehicle tire, looking underneath a vehicle or even illuminating a building. 4 points ------------------ Items of Note: Excellent Customer Relationship Management \| Battery pack may be awkward for some applications \| Straight cable versions could be welcome options 5 points
