Mole-Richardson 8811 is a daylight-balanced TweenieLED 100W 4.5" Fresnel. Apart from the black powder-coated finish, the TweenieLED head looks and performs the same as a legacy light allowing you to swap a standard light for a TweenieLED or mix them. In fact there's a retro-fit kit available to convert your old style light to an LED.
On-board local 100 - 10% dimming means you'll probably be restricting your scrimming to half-scrims, saving you a lot of ladder climbing. Besides comfort, you'll be saving on air-conditioning and head running costs in the studio. The TweenieLED's maximum draw is 0.5 - 1.0A as compared to the legacy lamp's 1.7A - up to an 80% reduction in energy consumption. This means that you can run double the amount of LEDs as legacy lights without raising the temperature. Let's also consider the cost and downtime of re-lamping. LEDs last about 50,000 hours and are virtually maintenance-free.
The 90-250VAC TweenieLED has a 4.5" lens, passive cooling and aluminum alloy and steel construction. It has 22 degree to 56 degree spot to flood variation and a 5/8" receiver for standard Baby pins. The #18 AWG power cable is 25' long and ends in a NEMA 5-15 Edison (US) plug.
