Video Light - what's the best battery or option to have it on constant?

[magnus2]

<p>I recently bought a lowel id video light (which is great) but the battery time is around 30minutes. IF I work somewhere there is electricity I would prefer to plug it in and not having to worry that the light will run out - or buy a bit bigger battery which lasts an horur or so?</p>

<p>Does anyone have a recommendation ?</p>

<p>I would think if you add one or more batteries and wire them in parallel that would give you more time. But you should experiment with it first. And don't hold me responsible if it kills your light!</p>

<p>You should have no problem finding a battery suitable for 2 hours or more of operation. That would be sufficient for a day's shooting if you turn the light off between clips.</p>

<p>Look through the video chapters at B&H for ideas. There are belt packs for serious (50W or more) power. Anton-Bauer makes the best on-camera batteries. A-B has a two or three Li-Ion batteries which have the best power/weight ratio. Mine will run a 20W light for over three hours, including the camera (50W). Lead-acid batteries are the cheapest for the power, but very heavy. Ni-Cd batteries withstand an heavy current draw (better than Li-Ion) but are subject to "memory" effects. Keep your checkbook warm.</p>

<p>You might also look at one of the LED light panels ($$). The color temperature is approximately daylight, and the power draw is about 25% that of an hot light. Be aware that video lights do not have a lot of output. (Think video = 1/30 sec, f/1.8 at ISO 800 (+18 db).)</p>
