Very Interesting would like to see some closer photo's of the lights. I to would be willing to test some out for you.


Thx! Will get more photos when I decided the final design for lamps. The lamps you see in this pic are my earlier designs.

The inner voltage is 24V DC, and can be connected to 100~240V AC or external 24V battery case.


Without AC power connection, you can still use this light at about 8000 Lumens for 3.5 hours (4 Lamps at Max with standard battery config.)

For use in the US, I would suggest 12 volt version. This would facilitate vehicle mounting applications. Also, a small electric telescoping tower or mast that could be operated by wired, IR, or radio remote control.

Thank you all people. We have good progress on the sample production.


The samples will be sent out soon, in 1 or 2 weeks.


You will find it easy to carry, to install and to use.

Hi all.


I will send out the first sample to our fellow member Solvarex tomorrow.


And will send more day by day.


One question:


Who will be OK to receive and test them in thanksgiving holidays? The samples will be sent to you priorly.


Thank you all very much!

I will be able to test during the Holiday's. When off of work, I have more time to do stuff like this. My back yard is completely dark at night, no other lighting around. Can test the night that it comes in technically. Would love to test this product for you.

I'd be willing to test 'em. I work in a Park system, and we often have incidents in the woods & such with no available lighting. We work with generators & floodlights.

And if you want the testing to also take place in Canada, I would love to test one out for you. No issue with Thanksgiving holidays here, as we celebrated Thanksgiving last month. I'm Canadian Forces Military Police, and my area includes a lot of unlit areas.

I work EMS/Fire/Rescue/and Emergency Management. Alot of my work is in the country with no lighting. I can defiantly try these out, as one of the main functions I work with is providing additional specialty lighting at scenes. We have portable light plants that we use, as well as numberous generator/light stand combos that we use and provide at anything from fire scenes to vehicle wrecks to crime scenes to death investigations. I could defiantly provide some good real world feedback and testing, as part of my compound is somewhere around 30 acres of open fields surrounded by trees.


Thanks,


Paul

Haven't been to the office yet to check it out but the office staff have confirmed its arrival. Looks like the light unit is out of customs and should be here early this week, if Canada Post is to be believed. Review to follow!

Good afternoon. Im knew to this forum. My fire department is now part of a haz mat task force that covers a vast majority of Nassau County Long Island NY. I would love to get some more info on this and maybe even try them out. PM me if you have any questions.

It's here! I'm not in the office but my GM opened it and texted me. Now bear in mind she's not really into this kind of stuff, but her words were "I'm really impressed!" so it's gotta be good! Now I'm anxious to get down there and see it! Should have pics and first impressions tonight.

Well, we have it. This unit is NICE.


The main system is housed in a Pelican-style suitcase-sized case with wheels, about 21" x 18" x 8". It has double throw latches for easy opening and handles on three sides for carrying and stowing/removing in just about any position. A retractable plastic handle is integrated with it to pull the unit along without carrying it. Nameplate, purge valve, and rubber seal are standard. Total weight of the packaged unit is 34.5 lbs with all lamps, masts, chargers, and the battery.


On the outside of the case are several connectors, switches, and mounting points for the lights. The four mounting studs are approximately 1" diameter solid aluminum and about 1.5" high, mounted to the top of the case. The base of each stud is an aluminum flange within the case about 3/16" thick and held in place by four hex screws. These things are SOLID and provide the foundation for placement of the lightheads.


The side of the case features four sockets with potentiometers for connecting the lightheads. Each socket is protected by its own captive screw-off cap with a rubber seal for weather protection. The sockets and mating plugs on the lightheads are splined so they will only plug in one way. The pots above the sockets permit for the dimming of the lamps to reach a desired intensity; you don't necessarily need full power all of the time. Beneath the sockets is the large power switch which activates all four lamps, along with an LED indicator which presumably indicates battery strength. Towards the bottom are two more sockets, a two-prong and a three prong which facilitate the AC adapter and charger respectively.


Opening the unit reveals the substantial circuit board, wiring, and battery. The battery is a behemoth of a unit that is held securely in place with velcro on two sides. It is 24 volt, 10 Ah with a Li-Fe chemistry, which provides a huge safety margin over traditional Li-ion or Li-Po batteries. There is a small strap included to help tie the battery down but seriously, it's not necessary. Just one patch of velcro holds it in so securely that when I tried to take it out, I couldn't! Gotta try harder next time. The circuit board contains the driver circuitry and connection points for the wiring to the case and battery, all beautifully loomed and very professional. It uses PC-type standoffs to secure itself to the case which is one weak point on this system. During shipping someone must've not been especially careful and dropped the parcel, which caused one of the standoffs to shear and allow the circuit board to loosen up. Fortunately it is held in place with two more standoffs and the foam in the case and won't be going anywhere, but I believe this part could use a revisit by the engineering team.

On to the lightheads!


The case contains four aluminum telescopic masts, each about 12" long. The sections are held captive within each other and are clamped/released with plastic throw levers, much like a camera tripod's legs. Extended length is just over 55" from end to end. The bottom lever secures the mast to the aluminum stud on the case, while the top lever permits the mounting of the lighthead.


Also within the case are four LED lightheads. We received two flood and two spot. The aluminum bodied lightheads each contain four LEDs with TIR style optics. The spot head is clear in front of each diode while the flood has a textured diffuser over each diode. The face of the lamp is protected by glass. The housing itself is roughly 3" square in dimension but has a rounded profile when viewed from the front. The back of the lamp assembly has a large aluminum heatsink with an individual square-post design. The main housing surrounds this with additional slots cut for heat dissipation. The top of the lamp features a polymer handle used to aim the beam while the bottom contains the mount for the mast. The mount is an aluminum swivel ball (again, like a camera) held tightly with a wingnut set screw, and a 0.5" diameter by 1" long aluminum stud with which to mate with the telescopic mast. Power is provided with a heavy duty, rubberized, coil cord with screw-on plug to match the one on the case. Entry to the lighthead is done with a solid plastic base which the cord passes through, and is tightened down with a concentric nut that passes over it and tensions around the cable 360 degrees.


The unit also came with two external power devices, the AC adapter which allows use of 100-240VAC to power the unit and comes with a standard North American NEMA 1-15 style plug hardwired to the unit, and the Li-ion charger which has a Europlug input cord that is detachable. The charger also claims to accept 100-240VAC input and the AC connection is a standard two-prong input which can be sourced locally.


Now since I'm writing this in the daytime I can't really give a good comparison for brightness yet, but we fired it up in the shop and....DAMN.


For a prototype this is one slick unit. We want to keep this one and buy more but it will really depend on the price. Regardless, I'm adding one to my personal crew kit, no question. This sure beats hauling a generator, extension cords, gasoline, and halogen floodlights around! Granted LED technology might not quite be up to producing the same volume of light as a 500W halogen when viewed from a practical price perspective, but the convenience and versatility of this unit far and away exceeds using a halogen setup.


Pics soon!

The reveal! Forgive the iPhone pics but it really takes better stills than my Pentax, and my girlfriend is too protective of her 40D to let me borrow it. :(


The whole package.

The unfortunate sheared standoff. From what the office staff tells me, Zheng packaged this thing like a tank! Guess Canada Post can find a way to bust anything! :mad:
