Concept 101L Cordless Remote Control LED Picture Light- 11 1/2 inch Polished Brass

The ultimate picture light-cordless, bright, dimmable and remote controlled..
Advanced solid state circuit using PWM (Pulse Width Modulation) technology to provide over 100 hours of life (on brightest setting!).
Lamp uses 4 "D" batteries, remote control uses 2 "AA" batteries (not included).
Superior Quality "Warm White" SMD LED's included to provide warm color rendition and even light distribution.
Universal remote-one remote controls multiple lights.

6200K Color Temperature | Voltage Range: 9-40 | CREE XP-L | 30,000+ Hour Life | Backed by 5-Year Warranty.
Adjustable beam to fine-tune alignment for precise optical outputs.
Pulse width modulation to eliminate flickering in most applications Certain vehicles will still require resistors.
Quiet, high efficient cooling fan to keep LEDs running at full brightness throughout bulb life.
Before purchasing, please check clearance requirements as these bulbs are larger than stock.

TNB runs more smoothly with no friction, making the fan silent, powerful and highly durable (200,000hrs).
PWM function automatically adjusts fan speeds according to the CPU temperature for efficient cooling and minimized fan noise.
Bearing Type: Teflon Nano Bearing.Noise Level: 10 - 21.5 dBA.Air Flow: 64.75 CFM Maximum.PWM (Pulse Width Modulation).

Featuring a slim and compact look-the ultimate picture light-cordless, bright, dimmable and remote controlled.

The Orion Dew Zapper Pro is an advanced 12-volt DC dew prevention and elimination system which can power up to four heating bands to prevent dew accumulation on all your optics (heating bands sold separately).
Microprocessor-controlled circuitry delivers pulse-width modulation for precise temperature control of up to four heating bands.
Each heater output has its own temperature control knob with adjustment from 0% to 100% so you can set each one to your preference.
Heating bands are power-efficient, drawing only 0.25 amps to 2.8 amps at maximum output (heating bands sold separately).
Don't let dew dampen your spirits, or your telescope optics, get the made in the U.S.A. Orion Dew Zapper Pro today.
