- Compatible with all A-Size dedolight accessories and optics.

The 400W HMI focusing light head by dedolight embodies everything professionals have come to expect from the brand. Its double aspheric lensing creates the cleanest and most controllable beam in its class. Few users are prepared for the range this popular light head achieves without additional accessories: a native flood-to-spot range of 50°–4.5° and a focal intensity ratio of 1:20, adjusted simply by turning the focusing knob.

Consider the time saved compared to traditional 400W HMI fixtures, which require multiple attachments to change beam angles—this dedolight pays you back in efficiency.

This light can also be requested with a tungsten ceramic HMI lamp, which delivers four times the output of traditional tungsten lamps. Using either lamp, the flicker-free DEB400DT electronic ballast allows switching between 400W and 575W, with dimming up to 40%.

Beyond the native light performance, a wide range of optional attachments can be added in seconds, without tools. If you’re accustomed to using other 400W HMI projection systems, you must experience this light with its DP400 projector—or the DPBA-1419 Intensifier (boosting output up to 528% in a tight, parallel spot)—before considering any other 400W HMI system.
