What is low-voltage landscape lighting?
A 12V system: a transformer steps mains power down to twelve volts, and buried cable feeds fixtures that are safe to handle and legal for a homeowner to touch. It is the standard for residential landscape lighting because the low voltage removes the shock risk, the cable does not need to be in conduit at code depth, and fixtures can be moved as planting grows. The guide covers transformers, wire gauge and voltage drop.
Low-voltage or solar?
Solar costs less up front and needs no wiring, but output falls off through a Houston winter, the batteries degrade within two or three seasons and brightness is not consistent across a run. Low-voltage costs more to install and gives the same light on night four hundred as on night one. The guide sets the two side by side on cost, lifespan, brightness and maintenance.
Is professional installation worth it?
Sometimes not, and the guide says so. For a handful of path lights along a short walkway a good DIY kit is a reasonable buy. The case for professional work is transformer sizing, voltage drop across long runs, beam angle selection and aiming, and fixtures that survive more than three Houston summers. It is the aiming that most homeowners underestimate.
How long does it actually last?
Solid brass and copper fixtures routinely run fifteen to twenty-five years in this climate. Integrated LED modules typically give thirty to fifty thousand hours, which at roughly six hours a night is fifteen to twenty years. Cheap painted aluminium is usually the first thing to fail, often inside three years. The guide breaks down what fails, when, and what it costs to put right.
What colour temperature should I use?
2700K for almost everything on a house: it flatters brick, limestone, stucco and skin tone. 3000K works better on heavy green planting where warm light can read muddy. Anything at 4000K or above looks like a car park. The most common mistake is not the number, it is mixing temperatures across one property by replacing failed bulbs piecemeal.
When should I book Christmas lights?
September and October. Houston installers take bookings from late summer and the good dates are gone by mid-November, which is exactly when most people start thinking about it. Installations run from the first week of November, most homeowners want them lit by Thanksgiving, and takedown runs through January. The guide lays out the real calendar.
Why we publish these
Most lighting company websites answer questions in a way designed to make you pick up the phone rather than to actually inform you. The page looks like an answer, gets three sentences in, and turns into a call to action. We would rather publish the real answer, including the cases where the honest recommendation is a cheaper option, a repair instead of a replacement, or no purchase at all.
There is a commercial reason as well as an honest one. Outdoor lighting is a considered purchase that most homeowners make once. The people who read three or four of these guides before calling already know what they want, already understand why brass costs more than aluminium, and have a realistic budget. Those conversations are shorter and better for everyone. The people who read them and decide not to buy were never going to be happy with the price anyway.
Every guide is written from what this crew sees on Houston properties, not from a manufacturer’s marketing copy. The failure modes described are the ones we dig out of flower beds: corroded splice connections, transformers undersized for the run they were asked to feed, fixtures buried by two seasons of growth, and the mixed bulb colours that come from replacing failures one at a time with whatever the hardware store had in stock.
Comparing quotes
What to ask any installer
If you are collecting quotes, these are the questions that separate a system built to last from one built to a price. Ask all of them, of everyone, including us.
What are the fixtures made of? Solid brass or copper, or painted aluminium? This is the single biggest predictor of how the system looks in year five. How is the transformer sized? You want a number and the reasoning: total fixture wattage plus headroom, not “we always use the 300 watt”. What wire gauge, and what is the voltage drop at the far fixture? A long run on undersized cable means the last fixtures are visibly dimmer and burn out early. Is the LED integrated or a replaceable lamp? Both are defensible; you just need to know which, because it determines what happens in year twelve. What colour temperature, and is it the same everywhere? Who aims the fixtures, and when? Aiming has to happen after dark, with the system live, and often a second time once planting fills in. What does the warranty actually cover — fixtures only, or labour too, and for how long?
An installer who answers those seven crisply is worth talking to. One who deflects to a monthly payment figure is not. If you would rather go deeper on any of them, the guide on low-voltage systems covers transformers, gauge and voltage drop properly, and the lifespan guide covers materials and warranty.
About these guides
Common questions
Who writes these guides?
Elwin Brown, the owner, with input from the crew. They are based on what actually happens on Houston properties rather than on manufacturer literature, which is why the numbers in them sometimes disagree with what a fixture box claims.
Are these specific to Houston?
Yes, deliberately. Heat, humidity, clay soil that moves, heavy summer storms and mature live oak canopies all change what works here. Advice written for a dry climate will tell you things about fixture finishes and cable burial that do not hold up in Harris County.
Will a guide ever tell me not to hire you?
Several of them do. The guide on whether professional installation is worth it is explicit that a short path-light run is a reasonable DIY project, and the lifespan guide will often point you toward repairing an existing system rather than replacing it, because repair is usually a fraction of the cost.
How often are they updated?
When something changes that matters — LED efficacy and pricing have both moved a lot in recent years, and lifespan figures have moved with them. If a number in a guide is out of date, tell us and it gets corrected.
Can I get an answer to something not covered here?
Call (832) 303-0428 and ask. There is no charge for a question and you will not be put into a follow-up sequence for asking one. If it is a question we get more than a few times it will probably become a guide.
