Home Depot LEDs
Home Depot LEDs
I just bought these since they are a replacement for the MR16 style and at 5.5 watts that's like roughly half an amp of draw..not too bad vs the 20watt amp and a half draw. They pretty bright but at $20 a pop, they are a bit on the expensive side. On the good side, if they last as long as they say, that would easily save me money replacing these things if/when a normal halogen goes bad. Here's what they look light inside my housing. There almost identical to the halogens except the outside diameter is just a hair bigger. Here is my pin connection, I can use existing two pin connector I found a bunch of, or I can crimp some pins and pot some new connectors.

Re: Home Depot LEDs
I like it. I am investigating all kinds of lighting options. Will they support PWM signals for dimming. I am going to be working in a low visibility area and depending on suspended particulate the lighting will need to change.
Dose the housing have a plexi lens or are you just using the factory lens?
Thanks

Re: Home Depot LEDs
Well, on the box it says not to be used with dimmers..so I'm leaning towards no dimming. I have a 1/4" thick acrylic piece in front of the LED. I will try dimming them and see what happens with an Ardunio and a transistor. If I blow it up..so be it. For science!!

Re: Home Depot LEDs
That sounds great. I will probably be using them on my project. Keep me informed. I was looking into high output led plates but they are ridiculously bright ( 5000L )and require about 20v . plus I think smaller lights like these will be nicer because I can have more for a better array.
If you do the arduino transistor test. let me know the specs ( what is the pwm limits i would probably say half 127 would probably be low enough)
my guess is they don't want you using a dimmer because they appear to be for in door use (120v ac ) converted to dc and most dimmers operate on the ac so the rectifier regulator circuit in the light fixture would be getting pulses
I am just going off my experience with residential construction
and what depths have you taken those light housings to. Just curious.

Re: Home Depot LEDs
Nice work. Can you explain your housing in a little more detail? Also, what kind a wattage are you giving them? Do they need a special driver or are they wired direct to relay?
Re: Home Depot LEDs
Hey,
whats about the cooling part? Your LED will become very hot inside your PVC-housing...

Re: Home Depot LEDs
Heat. Well, I'm sure they will build up some heat. But I figure since they will have an off and on switch and won't be on 100% of the time and housing will be surrounded by much cooler water, I don't think that will be a big issue at the moment. The construction is a mock up of the how to section on Homebuiltrovs.com main site. I just modified it a little so I can replace the bulbs if needed. I'll have a solid state relay or a mosfet handling the On/Off. Depths unknown but I'll have a complete assembly done and in the water soon.

- I used these to squish the o-ring down then ban-sawed the rest off.

- I liked these couplings since it has a nice shelf for the o-ring to sit on.
