Inspiration by Ra The Maxablaster

Project - Make a LarryK14 (Par 64 GE-Q4559X 28 volt 600 watt Lamp) and then fit a 1000W Landing Light (Par 64 GE-4556 28 volt 1000 watt Lamp)

Using Parts List

JM-SST (JimmyM Soft-Starter with Trim)
DeWalt V36 Pack (10xA123) (eBay)
inc. DeWalt built-in charger
DeWalt Pack Power-Charger (eBay)
UK Homebase 5,000,000 CP Lantern
Par 64 GE-Q4559X 28 volt 600 watt Lamp (SkyGeek)(Google +Try Variant Spellings)
Par 64 GE-4556 28 volt 1000 watt Lamp (SkyGeek)(Google +TVS)
Muldental 6.0 sqmm, 0.75 and 0.50 UltraFlexible Silicone Cable (also Google Super Flex)
2x Deans 50A Male and Female (1 Female PCB mounted)
1Meg Pot

Note: Q4559X (MBCP 765,000)with halogen capsule is brighter than standard Q4559 (MBCP 600,000)

Note: 4556 not listed in current GE/Silvania/Ushio literature

Alternative. . . 4557 Dual filament version 400/1000 ? (MBCP 600,000) ~ Bigger, less bright hot spot but more total output than Q4559X same as 4556 . . .

I wanted to use the De-Walt pack almost as is - stripped of outer casing but utilising the standard charger. The pack in V1 form is very simple as everything stays where it is and just need to be strapped together. The V2 pack (Slim and Tall) need. the built-in charger to be relocated and the balancing wires extended.

An Emergency Cut-Out Switch is made from a Deans Female on PCB and a Male with a wire loop. This has the added function of providing an external position to check current using a DC Clamp Meter.

Artists Mock-Up



1000W Filament



600W Filament (in Halogen Capsule)



Dremel edge ring to accomodate deeper PAR64



Dremel Battery Bay - Less needed for V2, only requires a small amount from the rear door bottom edge and fillets on cross screw housings



Dremel slot for copper heatsink (remote mounted FETs from JM-SST)



1 FET removed from JM-SST, mounted on heatsink and second added !



FETs in place



Easy V1 pack - everything is where it was in the original DeWalt package



More work - Extend balance connectors and cut slots in top cage to allow underside connectors to bed in nicely



V1 - Chamfer front edge of connector to allow easy access to battery bay



V2 fit in with the bottom edge taken down about 1/8 inch



6.0sqmm cable and 50A Deans - The standard DeWalt connections are not rated as highly so are only used for charging



Charging V2 pack



FETs mounted and cabled (White is gate signal and Black is Neg In and PWM-Lamp Neg, Small black is Batt-Neg to the JM-SST)



JM-SSTmounted -> Red - Switched Pos, White - Gate Signal, Black - Batt Neg



Deans Emergency Cut-Off PCB and Main Switch to JM-SST



FET Copper Sink + Xtra External heat sink ( I had it spare so . . . )



Emergency Cut-Off, JM-SST Trim Pot and Volume Knob (now connected - working well - HMMMMM)



Cut-Off again



Final (?) Item

Hi

Added Voltmeter (Battery Pack Voltage)

and second power pack for double runtime and less stress . . .



Amazing how long "just" adding a voltmeter and a second pack takes . . .

Sleeper mega mod!!

Re: 1000W Build . . . Pix

That looks like a well-thought-out build.

What is the metal box on top of the battery pack?

It seems like that PAR lamp would get too hot for the plastic case. Does it reflect enough out the front to keep temps down?

Oh, and this thread seems startlingly devoid of any pictures with the lamp on...

Re: 1000W Build . . . Pix

Pardon the stupid question, but is that a HID?

 

[paulr]

Re: 1000W Build . . . Pix

HID = high intensity discharge = basically an arc lamp. They are around 3x as efficient as incandescents but have various shortcomings and are expensive. In portable lights most of the ones we see are 35 watts and 3000 or so lumens. The 1kw light in this thread is not HID, it's a monstrous incandescent. Wow!

Still work to be done . . . !

Metal Box is the DeWalt built in Charger/Balancer.

PAR lamp throws almost all the heat right out of the middle of the lens. Almost none gets backwards - Remarkable.

BUT the Pack . . . More on that in a moment.

Test run last night and then sleep as had worked allmost all day soldering and fitting and posting photos . . . too tired to add words and do more photos !

That about sums it up - Thanks paulr (correction)

Now - Heat

The PAR64 1000W produces a lot of heat out of the front but doesn't get hot in the back and sides - so that's great.

BUT - CAUTION

Pack gets very HOT during a "long" run. Maybe the DeWalt pack strapping is not rated at 35A - the std. output/charge connections are almost certainly not, which is one reason why I added the Deans. All the data on the RC-Groups threads and other sources say that the A123 cells don't heat up much even under extreme load (30A+). Tried an extended 3 minute run and nothing got too hot - or so I thought - but in fact the pack was boiling hot and at 35A the power drop at the end was truly precipitous. Whether from heat or over-discharge a cell had failed 0.0V (the others were at 2.9V)

So no extended runs, and I have ordered a small Volt Display to add on the top to monitor Pack Voltage.

More photos when I get a chance . . .

Pete

Re: 1000W Build . . . Pix - Now with Added Words

Smashing Build! I really like how you made the heatsink. How warm do those things get?
My regulator will use a MOSFET driver, which can drive 1-4 MOSFETs. Instead of building more boards for specific L14K type designs. I thought I would just make the JM-SSR capable of driving multiple MOSFETs in it's base form. Then just add external MOSFETs.
I know plasmaman had a failure using a single MOSFET and a 1000W bulb. So it looks like 600W is OK with a heatsink on a JM-SST, but 1000W requires dual FETs.
Bravo!
How about beam shots?

I know what an HID is, it just wasn't immediately clear if this was an HID or not to me. Though I should have figured it out from a picture of the filament.

Re: 1000W Build . . . Pix - Now with Added Words

Hello petrev,

Congratulations on your outstanding build. Excellent pics and post too.

I have a Q4559X. How does the 4556 compare? Is it considerably brighter? Is the beam similar? Does it throw farther? How is the spill?

I am curious because my HyperBlitz beats my Q4559X LarryK14 in all areas except spill.

Is there any way for you to take comparison shots between the Q4559X and the 4556? There are a few CPF members that are familiar with the former and it would be great to get an idea of how much brighter the 4556 is.

Regards,
Mark

Hi Mark

I think it is quite a bit brighter, maybe more focused but not sure (maybe not quite as white as not overdriven - but still impressive - trouble is they both make you go a bit blind ! ). I really need to get it next to another one or get out there and do the photos - My nice camera is bust and my Pocket Camera just isn't as easy for taking manual shots, but I will get to it soon . . .

Plasmaman is building one - he has the LarryK14 that inspired me to do a similar mod and then we found the bigger bulb and thought - Why Not?
At some point (soon) we will get them together and do a side by side comparison . . . easy to load either lamp of course.

Love your HyperBlitz by the by

Cheers Pete

That would be great and I'm really looking forward to it.

Love your HyperBlitz

Thank you, it is a lot of fun. I need to build something considerably brighter now though. The madness never ends....

Mark

Man!! That is kickin'!
1000+ watts!
I sure wish you could make it to the Dallas Fort Worth area this summer with that monster. :thumbsup:
Keep up the good work! :goodjob:

Re: 1000W Build . . . Pix - Now with Added Words

HOLY!

Let.there.be.LIGHT! :tinfoil:


I like the way the charging grommet's used for the trim pot, and the copper heat sink slit.
:goodjob:

What I don't get is why..the two battery packs, V1 and V2. And two lamps.
Pity about the Dewalt pack, getting so hot. Disappointing.

Thanks for the photos.

Hi Cat

Thanks for spotting the trim pot behind the charging grommet - I thought that worked out really neat too.

Why two battery packs ?
Well the idea was to produce a simple pack from the DeWalt that could be charged using the standard charger that is available really cheaply (?) to U.S. so that people without A123 chargers might benefit . . .

That is the V1 - Straight out of the Std. Pack and just strap it all together and add the BIG output cables and Deans plug - easy and quick !

V2 is just because I might be getting another host that has a narrow/taller battery compartment so I decided to try to make a pack that would fit both hosts.

If someone wants to copy this build then just do the simple V1 - it works fine and only needs a bit more Dremel work on the inside.

. . . And - Why two Lamps ?
Answer - Personally I think the Std. LarryK14 Q4559X is probably the most "sensible" as it runs for a bit longer (22A vs 36A) and everything will be less stressed - but - as I saw the 1000W lamp existed I just had to find out if it would work and whether it was much brighter/sharper/impressive ??? I think I will probably actually "use" the Q4559X version more often but the 1000W is now just a swap away when extra is needed.

Well done Pete. V-Nice.

Ta Mate

This is great. :thumbsup: I might upgrade my Larryk. Comparison shots between the original and this would be interesting.

Hope to get some beam shots tonight if I don't screw it all up fitting the Volume-Mod !!!!!!!!!

Cheers
Pete
