New 18,000W Single Ended lamps use a sturdier GX51 lamp base for which ARRI engineers have designed a special lamp holder. The new lampholder alleviates mechanical stress from the lamp pins, which now serve only as an electrical connection. The lamp clamping mechanism is self-aligning and uses a rugged, recessed lamp lock handle. To ensure that crews can easily use 12,000W lamps or versions of 18K Single Ended lamps with G38 bases, the new lampholder accepts either lamp type with no modification or adjustment required.
