Was tired of buying bulbs for my dewalt lights. Bought 2 of these to put in my dw908 & dw919 Fit very well just screw off the old lens and remove bulb screw on replacement led thats it done better light and way more battery life lil pricey but worth the money if you use these light for work!

The first thing I did was take mine apart. It has a DC-DC convert so it has about the same brightness at 12V or 18V.

Here are my measurements (plus or minus)

8 Volts 0.000Amps = 0.00 Watts (theoretical min of 12v pack 0.8v*10cell=8V)

9 Volts 0.250Amps = 2.25 Watts

10Volts 0.450Amps = 4.50 Watts

12Volts 0.360Amps = 4.32 Watts

14Volts 0.305Amps = 4.27 Watts

16Volts 0.260Amps = 4.16 Watts

18Volts 0.230Amps = 4.14 Watts

20Volts 0.205Amps = 4.10 Watts

21Volts 0.195Amps = 4.095 Watts (theoretical max of 18V pack 1.4V*15cell=21V)

This should run 33% longer on an 18V battery vs 12V battery.

I wish I had a way to measure lumens or luminous flux(whatever). Package says 110 Lumens.

I would guess this is a Buck DC-DC since LED's usually require around 2-3 Volts. Diodes tend to be one of the big losses in energy so at higher voltages you can get better efficiency. Im guessing thats why the Watts are going down with higher voltages because the DC-DC converter is running more efficient. Maybe later I will get board and reverse engineer the circuit.

Smoother, better filled, whiter light with good color rendering.

Strong center spot with good wide angle distribution.

Draws 240mA at 18V for 4.3 Watts of power consumption = a very bright flashlight.

Run time about 10 hours with 2400mAH rated 18V XRP batteries.

This is over 3 times the run time of the 900mA standard bulb, with much brighter and more useful light

Not cheap but it makes the DW919 far more useful.

Honest reviews on DEWALT DCL0900 Replacement LED Bulb

This is the perfect solution to replace the old-style xenon bulb in a DeWalt work light. I've always disliked the xenon bulbs, they don't put out that much light and get very hot. The LED light is brighter, whiter and so much cooler. I'm sure the battery life will be better as well.

I bought this for my DEWALT DW908 18-Volt Pivoting Head Cordless Flashlight. The light runs cooler now and I'm sure the battery life will improve but I haven't tested it myself yet. I'll probably order another one for my flexible neck 18-Volt flashlight.

UPDATE I was at a DeWalt factory service center store recently (Sept 2012) and they were selling this item for over $40. While my review title says "a little pricey" the Amazon price is a lot better than the DeWalt direct price.
