The Dynamic LED Heat Sink Housing is a combination heat sink and housing for LEDs; specifically designed to hold a 20mm Carclo optic lens and a 20mm metal core printed circuit board (MCPCB) star LED. The Dynamic housing is a two piece design, machined from 6061-T6 billet aluminum, that easily screws together, concealing your LED and optic. Additionally, the Dynamic housing includes 4 small channels around the diameter of the sleeve to increase surface area and aid in passive air cooling. The completed size of the unit is small, sleek, light weight and while not technically waterproof it can be used in conjunction with clear silicone or our LED Seal.

Seen in the video to the right and as mentioned earlier this LED housings connects together via male & female threads. The two piece housing consists of a slug and sleeve, with the slug having male threads that screw into the female threads inside the sleeve piece. Before screwing the pieces together, the LED gets placed on the slug with either a thermal grease or epoxy and the optic will sit on top of the LED. The slug has a small 1/8" diameter hole through the center for wires to pass through and connect to the LED and the bottom of the slug has 1/2" national pipe thread (NPT) for mounting. And finally, to connect the housing the slug threads should also have thermal grease or epoxy on them before screwing into the sleeve. The LED and optic will self-center as you thread the two pieces together. We recommend our Arctic Silver Thermal Grease for the best heat transfer.


There are two variations of the housing designed to accommodate either a 1-Up and 3-Up LED.  The DLH-1UP-EH holds a 1-Up LED star, optic holder and lens; the DLH-3UP-EH is built to hold a 3-Up LED star and optic. Before adding an item to your cart, you'll need to decide whether you're going to use a 1-Up or 3-Up LED and select your housings accordingly.

1-Up Design

1-Up Dynamic LED Housing Heat SinkAny of our Cree or Luxeon 1-Up LEDs can be used inside the DLH-1UP-EH. There is a channel (see image on right) machined on the top surface of the slug piece that allows 24 AWG gauge wires to go from the LED star solder pads, underneath the star and through this channel, these wires then pass down through the center hole and out of the housing. The height of the optic holder and lens require the height of the housings to be slightly taller that the 3-Up version. Specific dimensions are listed below in the characteristics table.

3-Up Design

Any of our Cree or Luxeon 3-Up LEDs can be used inside the 3-Up housing (image below). These LEDs include a center hole on the MCPCB that matches up with the center hole of the slug. This allows 24 AWG gauge wires to go from the LED solder pads and down through the LED and heat sink. 3-Up Dynamic LED Housing Heat SinkThe height of the 3-Up (triple) lens is shorter than the 1-Up version; specific dimensions are listed below in the characteristics table.


The Dynamic LED Housings are modules only and not light engines; they do not include an LED driver. Just like any raw LED, these modules will require an appropriate power source and integrated circuit or LED driver. For selecting the correct LED driver, we have a complete guide on understanding LED drivers here.  Our recommendation for drive current is:  350mA for a 3-Up and 700mA for a 1-Up.

Need more light/power? Take a look here at our 5-10 Watt LED light engine housings. They feature the same design but with more heatsinking surface and added room for an LED driver.

Mounting Accessories for Dynamic LED HousingMounting

The bottom of the slug piece has female 1/8 IP threads (3/8 OD), which pairs with our 'all thread' nipple product and swivel (pictured on the right).  This is the most popular way to mount them as you can use the hex nuts that come with the nipple.  There is also 1/2" NPT thread on the outside base of these housings, which can be used for mounting; however we have seen these heat sinks used in a wide variety of applications where the threads weren't used at all. 1/2" NPT accessories can often be found in the electrical and plumbing sections in your local hardware store.
