Help choosing a lamp

[ratkilla 42]

Just wanting some info if any one can help with a lamp and battery set up. What im wanting is a lamping kit that the battery life lasts a hard long nights lamping, will a 12v 20Ah battery pack and the lamp will be a clulite lamp is this the top spec battery for the longest life duration, if so any ideas how long the battery would last ?

[Guest world.hunters]

not sure on how long that will last but all depends on how long you will actually be using the lamp as around where i live a clulite with a 12v 7 amp will last the night as we dont get many runs but as we are starting to travell further afield i have got myself a lightforce with a 12v 14amp battery pack.

 

between the 2 i would say the beem is better with the lightforce as you can make it a tight beam or a wide beam by simply turning the rim around the lamp, but i know alot of folks have had problems with the wires in these lamps and they usually end up stripping it out and rewiring them, although i have not had a problem as of yet.

 

the clulite is smaller and i personally think better made of the 2 it just feels alot stronger and would expect it could withstand more damage then the lightforce.

 

so the choice is yours but like iv said with the question on battery life it all depends on how long you will actually be lamping for.

 

 

hope this helps

About 3 weeks with a clulite

the drain on the lazerlite is half of what a lightforce is being 50W bulb in the clulite and 100W in the ligt force. with that battery and a lazerlite you'll get about 4.8 hrs of continuous lamp on time but the batt will be toatally drained then, so effective lamping time of around 4.5-4.6 hrs. still a long time.

 

same batt with a lightforce and 100W bulb will last you 2.4 hrs continuous lamp on time obviosly the batt will be pancake flat then.

 

wonder what the lightforce is like with a 50W bulb in? i use a lazerlite and its plenty bright enough for bunnies just could do with being a touch tighter i think. anyone tried the lightforce and a 50W bulb??

cheers.

a fully charged 16amp battery (wet cell) gives me a good nights lamping with a lightforce, 75watt bulb in it

i use the lightforce blitz with a 50 watt bulb in with a 12v 14amp belt pack off the back of the van(nearly always on this way)it lasts a good 4/5 hours no probs edited to add the beam is no different with the 50 watt bulb

i use a light force stricker lamp with a 18ah 12v battery the battery is light enougth to carry in a rucksack on your back and many times it last me from dusk till dawn when fully charged the battery was made to power a golf buggy and apparently it will power one of them for approx 8-9 hours constantly but i find that a battery dose not last along while being used intermittadly as the nature of lamping as they do when they are left on constantly so if you decide to test the battery of your choice for live of charge leave the lamp on time how long till batterys charge has gone then knock an hour or two off thats how long lamping live is in the battery.

What's the most lightweight kit then, if you're not planning to be out for hours?

I belive Chief is the man to ask on this subject

ELECTRIC POWER is the combination of the pressure or VOLTAGE times the flow or AMPERAGE. This combination is called WATT or WATTS. This is generally the unit of power that we use in assessing electrical systems. It functions as a common denominator for different voltages and amperages. For example:

 

10 Amps at 24 Volts = 240 Watts (Amps x Volts = Watts)

or

1,550 Watts at 120 Volts = 12.5 Amps (Watts / Volts = Amps)

 

One Watt powered for one hour is called a WATT HOUR.

1,000 Watts powered for one hour is called a KILOWATT HOUR.

just put the wattage of your bulb and your battery in amps in the above formula for continous

use times,for example a 100 watt bulb at 12volts=8.3 amps,so a 100 watt bulb would need 8.3 amps an hour,you have a 20 amp battery you could power it continous for approx 2 1/2 hours.

Another way is 20 amp battery at 12 volts=240 watts,this could supply 240 watts for one hour

hope this helps,

higgins this is all to technical for me couldnt you just put up all the variables for us thik feckers TOMO

cheers HBG, think ill look out for a cheap lightforce 170 and get a 50W bulb in it. the clulite is allright just could do with tightening the beam a bit i think.

 

what lamp you using tommo.

 

to see what the drain is just diveide the bulb wattage by 12v.

 

lightforce and 100W bulb: 8.3 amp drain so just divide the AH on your abttery by 8.3 and youll have the hours it will last for from a full charge.

 

lazerlite 50W bulb 4.16 amp drain so again divide the AH of your abttery by 4.16 and youll have the continuous on time from a full charge.

 

remember at this time the batterys will be totally flat and no good to run anything!

cheers,

Thanks for all the replys lads. The lamp's not for me its for a mate whos out in the states who im going to stay with, some may know him on here for his up and coming wrestling courier that he keeps on updating us on lol Now i'll find a decent setup and get ordering because when i got mine a while back it took about 3-4 weeks to come

clulite bag of crap lightforce everytime

20ah battery is the same weight as 17ah or 18ah. the heat on my back is what gets me, drowned with sweat. you wont go wrong with a blitz unless you need a scope mounted lamp
