constant-current LED driver or constant-current driver is used to regulate the amount of current that is supplied to an LED or LED array to maximize LED lifetime. If current is not regulated, LED brightness can fluctuate and life span can be shortened. The constant-current driver is used for LEDs or light fixtures that require a stable output current and operate within a range of voltages. Most finished LED products already have a constant-current driver or resistors to regulate current. If you’re building an LED fixture or replacing a constant-current driver, it’s important to verify that the output current and voltage of the driver is compatible with the LEDs’ current and voltage. If your LED product already has a constant-current driver or uses resistors in the LED array, you might need a constant-voltage power supply.

If your LEDs are dimmable and you want to change their brightness, choose a Magnitude Dimmable Power Supplies. These dimmable power supplies work by varying the power on the AC input side of the power supply by means of a TRIAC dimmer. This change in power on the AC input side will vary the voltage on the DC output side and control the intensity of the LEDs. TRIAC dimmers are common hardware store and household dimmers, which include brand names such as Lutron and Leviton.

Pulse-Width Modulation Dimming: Pulse-width modulation (PWM) dimming can be used to control dimmable power supplies such as Mean Well LPF Series. This type of dimming control adjusts the output current based on the duty cycle. As the duty cycle increases, current will increase and the LEDs will be brighter. Conversely, if the duty cycle decreases, the current will decrease and the LEDs will be dimmer. Pulse-width modulation for these drivers is based on a 10-volt signal level with a frequency between 100Hz-3KHz. The MLD-5A are compatible for this application.

Resistive Dimming: Resistive dimming can be used to control dimmable power supplies such as 12-Volt Mean Well HLG-40-240 Series or 12-Volt Mean Well HLG-600 Series or here.

The efficiency of a power supply or driver indicates the percentage of power that goes toward making your LED product function. An efficiency of 80 percent or higher is recommended for operating LEDs. 

When choosing a driver or power supply, the size of an LED product’s housing or area of installation is important. If you wish to put a constant-current LED driver inside of a product, the driver must be small enough to fit in the product’s housing. Similarly, if the driver or power supply is used outside of the product’s housing, it should fit the area of installation. Drivers and power supplies are available in a variety of sizes to suit your needs.

A Class 2 driver or power supply is in accordance with limited power levels defined by the National Electric Code (NEC) and fulfills the requirements of Standard UL 1310. Output is limited to 60 volts DC and 100 watts. Because power sources with this rating have limited output, it might not be possible to power as many LEDs or lights as those that don’t have a Class 2 rating. However, these power supplies and drivers provide protection from fire and electric shock.

A Class II rating refers to a double insulation layer between AC input and DC output wires. These drivers and power supplies do not require a ground connection.

Pendant lights are popular among many home designs. These versatile ceiling pendants unequivocally fit the bill in a variety of zones where points of light and design converge. Adding ceiling pendants over the kitchen island has been a design element we’ve seen and loved for a while, but interior designers and trendsetters are taking it a step further. We are starting to see designs incorporating unique, stylish pendants over dining tables, above the bath vanity, over the dressing table, by your favorite reading chair and over chic desks.

Whether your lighting design taste sways toward sparkling crystal or rustic farmhouse, selecting the correct size and number of pendants is key to creating a space that is both functional and beautiful.

Most people have air conditioning in their homes and though the temperatures don’t really drop too much even during winter here, there are definitely days on which there is a nip in the air, and if you have tiled flooring, it’s bound to get uncomfortably cold. While heating systems do help solve this problem, many homeowners are now transitioning to radiant heat. This provides very pleasant warmth to your body and feet as it warms the surface of the floor.

These under floor heating systems are suitable for hard floor surfaces such as living rooms, kitchens, entertaining areas, bathrooms etc. Since the air circulation is very gentle, there is a marked reduction in the amount of dust particles that get circulated, it’s a great relief for people that suffer from asthma and allergies.

When you are planning on getting this system installed, it’s important that you hire the services of a well-established and credible company; they will understand what your specific requirements are and then provide you the kind of solutions you need.

This type of heating uses heating cables that are well-embedded in the flooring concrete slab and it provides the right amount of heating. It essentially stores the heat during the night and then slowly releases it during the day and provides continuous warmth.

As you can see, there are a number of other advantages to getting underfloor heating systems installed.

One of the best ways to relax outdoors is by sitting in your own private hot tub. After a long hard day at work, a soak in the hot tub can help rinse away all the stresses of work and life in general. A hot tub is also a great way to entertain a few friends on the weekend. Once you have picked out the tub that you have been dreaming of, the next step is getting it set up and ready for you to enjoy.

Setup

Although you may be extremely excited to start filling your new toy up with water for that first use, hot tubs require an electrician. Santa Monica homeowners will need an electrician to help wire the hot tub to the home. These wonderful devices are not something you can simply plug into the patio outlet.

The tub or sauna will need to be hard-wired into the home’s power. Typically, because of the electric requirements, a dedicated breaker will be needed. Depending on the available service, you may need an additional breaker installed.

It is not uncommon for permits to be required for the setup and installation of a hot tub. An inspection may also be needed. A qualified professional will need to make sure the hot tub is wired correctly and safely. These are all things that will need to be handled by an electrician. Santa Monica residents can call The Electric Connection to discuss the setup of their new hot tub.

Maintenance

Like anything that is run by electricity, there are times when the unit will fail. Never try and fix the hot tub yourself. In many cases, you could end up voiding your warranty by doing so. If you ever run into trouble with your hot tub, call an electrician to take a look and save yourself time and money from a voided warranty. The Electric Connection is here to help you get your hot tub up and running.
