Cathodes on patio

I am looking for a cheap way to light up the patio. I was looking at the tiny bronze LED modules but it would probably take about 40 of those to light up the patio. I was looking at the cathodes and they are suprisingly cheap and long enough to take up a good area. Would these be a good solution for lining under the handrail of the patio?

Be sure to WATERPROOF the tubes/connectors/and transformers

I was thinking bout cutting into the bottom of the handrail to make it flush into the wood. You think that would keep water from getting to the cathodes?

I wouldn't recommend cathodes because of the weather and they are very fragile.

It just seemd cheaper and brigher compared to having to purchase 40 of the modules. I also looked at the weather proof LED strips but its about same price as 40 modules.

The Cathodes CAN be used but I'd STILL seal the ends up with silicone the biggest worry is trying to keep the transformers watertight as any water in them will kill them ... I used them in my grill for my car and even sealed up they'd still fry pretty regularly 1/2 a year ...
If it was me I'd do 1 watt flood bulbs

Personally I'm over cathodes and in the middle of a love affair with LEDs . LEDs provide a deeper, richer color where as all cathode colors seem a bit washed out after becoming accustomed to LEDs .

That said, however, there's no particular reason cathodes couldn't work for the kind of application you're looking at . They still have a leg up on LEDs in price, and in the ability to spread light evenly without the directionality of LEDs . But as stated above you -must- fully weatherproof the transformers, tubes, and cable connectors even if they are installed up under a handrail . In a stationary application like yours without the stresses of the automotive environment (broad variations in heat, vibration, impact with pebbles and road hazards) I imagine they'd be quite reliable .

Remember as you picture the installation in your mind that for every two cathode tubes, there will be one transformer that will need to be positioned with those tubes . You cannot just run one long daisy chain of tubes . The transformer is small but will represent a bit more of a challenge to mask in the installation than the tubes themselves . The wires between the transformer and the cathode tubes cannot be extended .

On the other hand, the ability of the cathodes to cast light in a 360 degree field isn't going to be utilized if they're recessed into a handrail .. in fact that kind of installation would be more ideal for LEDs with a wide viewing angle, which would likely cast a brighter light as well .

Why not order one pair of cathodes and one LED module or LED linear light (whichever style you think looks best for your application) and spend some time out with the handrail test fitting them and checking out the output from each in person to help you make your choice ? You may not use one in the final install but its a small price to pay to make sure you're making the right decision .

Good idea, Cooper. That makes the most sense. I think I will order a couple and give em a test. Thanks!
