Lumapower DX1 P7 Drop In Kit Review

[ernsanada]

I received the Lumapower DX1 P7 Drop In from Lumapower.

You can also purchase the Lumapower DX1 P7 Drop In or complete light from Battery Junction.

My DX1 originally came with a 5 Watt Luxeon and a K2 Led.

The DX1 P7 Drop In is very easy to install.

SSC P7 C-Bin LED driven at 2.5A.

My DX1 is using 2 AW Protected 18650's.

Also came with a OP Reflector which smoothes out the beam very nicely.

SSC P7 C-Bin

The kit comes with a OP Reflector and the SSC P7 Drop In.

Installed the rear screw from my previous module. The screw helps make contact to flat +ve anode of the 18650 batteries.

I removed the other module from the top of the battery tube.

Install the SSC P7 Module. The module screws in.

These are the lux readings I got. I am using a Meterman LM631 Light Meter measured at 1 meter. I waited 2 minutes before taking the readings. The Lumapower DX1 P7 is using AW's Protected 18650's. The ElektroLumens 2D, 3C Maglite P7 is fully charged Radio Shack C Nimh Batteries 1.2V 4500mAh.

Lumapower DX1 P7 (OP) - 7940 Lux @ 1 meter

Elektro Lumens P7 2D 3C Maglite (SMO) - 14,600 lux @ 1 meter


Refer to Elektro Lumens P7 2D 3C Maglite Review for more information.


The Elektro Lumens P7 2D 3C Maglite has higher lux readings because it's using a SMO Reflector. The Lumapower DX1 P7 is using a OIP Reflector.



In these beam shots the Elektro Lumens P7 2D 3C Maglite is using a modified 2D Battery Tube that fits 3C batteries.

The Elektro Lumens P7 2D 3C Maglite is using a B Bin SSC P7 driven at after 2 minutes. 2.92A. The light is Direct Drive.

The Lumapower DX1 is using a SSC P7 C-Bin LED driven at 2.5A.

The Lumapower DX1 P7 OP Reflector helps eliminate the "doughnut" holes usually associated with the SSC P7's.

Great review like always.:thumbsup: I've been waiting for your review since I saw you mention in the Manufacturer's Corner > Lumapower DX1 thread you had received a DX1 P7 kit. I also remember ElektroLumens saying he was pretty sure the Mag he sent you was a "B" bin. The OP takes quite a bit away for a DX1 to be only half as bright as your MagLite. There is the fact the that the Mag draws 2.9 amps vs 2.5 for the DX1. But I would have thought the Mag having a lower luminosity bin would have evened things out. I know you try to stay clear of making that kind of comparison. But it's a little surprising, if not disappointing. Thanks again for a great effort!

These are the same beam shots of the Lumapower DX1 P7 and the Elektro Lumens P7 2D 3C Maglite.

I used a faster shutter speed and kept the aperature the same as the other beam shots at 32'.

All shots taken at 32'

Great review and pics as always ernsanada! I have been tempted to buy one of these, but it looks like the P7 mag has both a brighter spot and spill. I do like a light running on 2x18650's over 3 nimh batts though. This review made my decision a little harder!

Great work as always!

Lumapower, as usual, has sought balance in their product; not total output.
Lower current = longer runtime, Regulated = steadier output, smaller/lighter package, OP/SMO = additional spill, greater usability.

Al Combs - the DX1-P7 isn't half as bright - a lux measurement like this doesn't measure total output it measures the hotspot at a known distance which is an indicator of how much the light can throw - not how much total light it's putting out.

I think a Intergrating Sphere may tell a different story on the lumens or lux measurements.

I also like the OP Reflector. It smooths out the beam gets rid of the "charateristic doughnut hole" associated with the SSC P7's with a SMO Reflector..

 

[MattK]

From the pics the 2D/3C seems brighter so I wouldn't be surprised at all if total output is higher, especially since it driven harder - my guess though is more like 15% - assuming 20% more current but with lower efficiency.

Any sense on runtimes?

These are the modules that fit the DX1.

Left to right, SSC P7, Luxeon V, K2

A knurled ring is needed on the Luxeon V and K2 to hold the module into the battery tube. A different reflector is also used.

The small screw is needed on all modules to make contact with the battery. The small screw is screwed into the back of the modules.

The Luxeon V and the K2 has a little more side pill which is hard for the camera to pick up.
