bosch 10.8v blue worklight

[big-all]

had it few days very impressed with the quality with the features and how long it lasts
if bright about a 40 or 60w old fashioned bulb has 2 power settings they seem to be about 15-20 percent duller but 55% more run time
it has a carabiners type loop
a magnetic in the carabiners base
a hanging loop and a great selection off angles

i have some figures but may have confused a 2.5ah and a 2ah but will update with further tests lol

a 9 year old 1.3ah battery on low power lasted a few mins short off 6 hrs [17.00-22.54hrs]

a 2.5ah 1 year old on low 10h 14m [13.30-23.44 this may have been the 2ah]
same battery on full 6h 22m [10.40-1700 again may be the 2ah but more likely the 2.5]
the worklight is indeed expensive at £35-40 but well worth the money as its compact and light

ok actual

1.3 low 5.54m high 3.25m
2ah low 12.16m high 6.21m
2.5 low 14.37m high 7.29m

decided to get a 4ah battery
i wonder how close to 24hrs it will get

I have a nice torch that goes with my 10.8v tools, it's fairly bright but too much throw and too little flood for use as a worklight. I have been thinking of ways to improve that but had trouble doing a conversion. Wish there was something like yours for my battery system.

[big-all]

what make/system do you have?

[Rorschach]

It's the Workzone (aldi) set which also happens to be the same as Draper Stormforce. My set is mixed between the 2 brands. The torch came with the workzone set, it's a 1W LED and it's a pretty handy torch, weighs hardly anything without the battery and the run time is really good, in theory with the 1.3ah battery it's about 5 hours. What I would have liked though is something positionable and with more flood. I have have a 12v LED floodlight that I made a little base for, it runs from a main adaptor but I can run it from a car battery or the 10.8v tool battery if I want to but that's not as convenient as having the neat package like yours.

these work really well very very bright

will only last about 1 hr on a 1.3ah battery you just need a lump off metal as a heat sink

BA, have you seen that all the Bosch 10.8v is being rebranded as 12v now

Those are the same as in my LED floodlights, I have experimented with that and they do run pretty well off the 10.8v battery, problem is you get max of about 2 minutes before they burn themselves out because there just isn't adequete cooling in a torch body, you need the big heatsink capacity of the aluminium housing of the floodlight. In just a few seconds of running the back of the LED got hot enough to stick to the skin on my finger!

i run several off tool batteries
2 in series run nicely off off a dewalt or ryobi 18v battery
you can also get them as 32v where instead off the 3 segment in each row being in parallel with each other the are in full series so perfect for a 24v[28.8v] bosch battery
you need to keep in mind a fully charged battery will be about 20% over volt so a 10.8v battery is actually a bit high for the first 1/3 off capacity as its around 13v
where as a 18v will give 21.6v perfect for 2 in series that will be 18[2x9v] and 24v[2x12v]
if run as near to the bottom voltage as possible you will get perhaps 20-25% less light but 2times the run time

i also run groups off these but suspect modern chip types are more efficient

That looks like what is in my current torch. Identical voltage, shape and output is about that too, maybe a touch higher. Do you have any idea of something I could replace it with that might put a little more light but also give good runtime and most importantly run cool?

[big-all]

i dont think you will get anything much different you may get say a 5-10% difference in any one direction or even 5% less heat 5% more run time and 5% less consumption but it may ruin a perfectly functioning torch for somthing that may not be any better or possibly worse as not specifically designed with the new led

[big-all]

these look interesting as 3-3.2v four in series will be 12-12.8v so work perfectly with a fully charged 10.8v[12.96v]

There is a voltage dropping circuit built into the torch, the voltage across the LED is just over 3v even though the battery is 10.8v
