<div dir="auto">I use City Theatrical mini dimmers with LED tape a fair bit these days. I get the 12V tape and rechargeable 3V batteries (123 size), and run them in series. If I need more power and have the space, I parallel in more sets or use 12V lithium iron phosphate UPS batteries.</div><div dir="auto">Hth,</div><div dir="auto">Steven</div><div dir='auto'><br></div>

It has a provision to illuminate it with a battery powered LED, that gets inserted into a clear tube that runs through it. However, a reviewer comments that they wish it were brighter. So, I have significant doubts that it will be bright enough for our needs.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">I imagine I would want at least 1,000 lumens of light. Ideally, it would be dimmable. I just looked at what was available for under cabinet LEDs, and found ones that would fit in that tube (I would put two back-to-back), and have the lumens I want. But, none of the 120vAC ones are dimmable, and probably wouldn't dim nicely at the low end if they did. I have a DMX to LED dimmer system that will work 5 to 24 DC. So I decided to check out the car work lights, that are hard-wired into the car. But, I have doubts they will fit into the tube.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">I am also a bit concerned about heat. Being installed in the inflatable, sealed with a vinyl tube around it, is going to reduce its cooling. So, perhaps bare LED strips are the way to go. If needed, I could perhaps wrap the LED strip around some metal tubing. That will both act as a heat sink, and I can get airflow through it, if I can find some old metal vacuum cleaner tubing.<br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Another related concept is to make my own inflatable shapes. But, use the fan-inflated type that uses nylon fabric. Then, airbrush with some transparent paint to add images and color. But, I have never attempted this. I see all kinds of paints advertised as transparent. But, will it stick to nylon?</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Any advice on the above?<br></div><div><br></div><div class="ydpc126ebb1signature"><div style="font-family:Helvetica, Arial, sans-serif;font-size:16px;"><div dir="ltr" style="font-family:Helvetica, Arial, sans-serif;font-size:16px;">-Joe<br></div></div></div></div></div>
