The transformer on an old one of these went bad and I replaced it with this. Was an exact match and fit perfectly.

Beware! Will not work with LED bulbs. Useless to me.

Simple to install

Excellent quality and easy to install

Exact replacement for difficult-to-find, more expensive offering from other vendors - but the price is still daunting. I needed this because transformer burnt out in one of 24 installed in different rooms 15 years ago.. Two-thin-pin bulb-insert connectors work both with halogen and LED bulbs.Note that I would only buy these as replacements, not as first-time installs , because (1) much more expensive than simpler, newer generation cans (although I could not find newer cans with transformers and do not understand how newer cans would step-down the voltage), and 2), Tricky for first-time removal of old ones and install of these ones because of difficulty of first-time figuring out spring retainers for fastening in the ceiling. The springs are stiff to disengage and engage and not obvious to see and recognize for beginners like me.Better clamping into ceiling and clamping of lens attachment than other same-generation, equivalent-use cans.

This is a very well built housing for retro ( or new ) lighting installs. Juno was thoughtful enough to include a cut-pattern to accurately make the precise hole in the ceiling. All components seemed well finished. The buyer will need a key hole saw - or a hacksaw blade holder --to make a clean ceiling cut-out. This project requires patience and intermediate DIY skills !

Just what I wanted delivered as quoted

I've installed over 20 of these, first a bunch of them in our kitchen renovation, then I put some in our dining room, and then some more in our hallway. First, the light from good quality MR 16 bulbs like Ushio, is just beautiful. Use Juno trims, which are also great, but costly, and study your bulb selection carefully. There are many websites that help the beginner lighting designer. The 'Lighting Bible' is a helpful book from the library. I found Taunton's book on kitchen design and renovation the best short yet detailed guide to selecting lights and installing them in a kitchen excellent. Buy a good 4 inch drill saw and learn to cut the holes nicely, learn how to spot the interfering joists and strapping that will make installing these units difficult. Plan your light placement carefully, if this redo is for your wife, then bring her into the detailed discussion of where each light is going to be placed and exactly how the cone of light will be placed on the counters or floor or cabinets. Give yourself a lot of time for planning every part of where the lights will be placed, it will save a lot of heartache later. Leave yourself at least 18" of unused cable to wire in these units, I think 2 feet is better. The junction boxes can easily become very crowded, if they were a bit larger that would make installing faster/easier. Managing the springs that hold the unit flush against the ceiling is a real skill. I've done at least 20 of these and sometimes it becomes a hassle to get a unit set fully in place. So, learn how to spot an easy spot to install the unit, and how to spot places to avoid. This takes practice and attention. Be extremely careful with the specs on clearance from insulation and wood in the ceiling. These are nice lights, but all MR 16 bulbs run extremely hot. Burning down the house is not good renovation. These things get so hot they can easily ignite insulation and/or wood if placed too close. So, read those precautions and follow them carefully. Remember to get a permit from your local building inspector and have him inspect your work in progress. Our local inspector was a master electrician and he was a great help. I don't like how the arm holding the transformer and junction box is attached to the light can. It flops around too much, and there is no easy way to straighten out an arm that is leaning over. I think the engineers could do a little more work on this aspect as well. Finally, these 'cans' are pretty expensive. The can plus the trim can easily run around $90 each, so if your doing the usual kitchen with 15 or more lights, that's getting into real money just for these units. I wired mine, and had some experience in an earlier life with electrical work. I would not recommend wiring these for a beginner in home wiring, just a bit challenging in several ways. But, the light qualify from these and a good bulb is beautiful. You also have a huge range of choices with the MR 16 bulb, color temp, light cone angle, wattage, and the huge range of trim effects. Also, remember to use the low voltage magnetic type dimmers, again be careful ordering as there are at least three different types of dimmers for recessed lights. I found the technical assistants guys at the bulb companies and the switch companies to be very helpful. Juno is a good quality brand in this work area. Finally, the light in the kitchen is beautiful. We're likely to continue using these lights in the family room and living room.

I had to squeeze these into a fairly tight space during my installation, but they still went in fairly easily. Installation should be a cinch in larger overhead spaces. I used LED bulbs (to reduce heat in the smaller space), I paired this with the Juno Lighting 449-WH 4-Inch Aiming Elbow Recessed Trim for a great clean look. Overall a good purchase.
