💡 Sylvania SYL64036 M400/U/ED37 Clear Metal Halide Lamp 400 W 4000K - Buy Now! Review

I have been using these lamps for decades. Don't be fooled, there is a big difference between "no-name" onions and Sylvania onions. These are industrial lights - I've had many unnamed bulbs that fell apart before I even took them out of the box. Spend a few euros more and be happy.

These bulbs are used to light my camp and when one went off the owner charged $100 for it. I thought these Revain bulbs might be incompatible or somehow worse, but they are brighter than the existing bulbs and the color is much less hazy. I've had two lightbulbs installed for over a month. So far no problems.

This bulb works great in my lamp. I would say it's a very bright white and the light output looks the same as any other lamp I've used.

The color is pleasant. When we sold the house, it was still working perfectly.

I'm glad I didn't spend money on a more expensive "brand name" garden bulb, I got the results I was aiming for.

After spending a lot of money on LEDs and expensive sodium bulbs I was able to find very good reviews on this particular bulb, I'm very happy with Sylvania and BT37 I haven't tried other well-known brands, but I compare it to HPS bulbs which are much more expensive. Don't waste your money on CFLs, LED or HPS, metal halide bulbs run cooler, try it and you can see and the light quality is amazing, everything alive reacts to metal halide, it didn't work with my digital ballast but it did with my…

The lamp was well packaged and arrived in perfect condition. These lamps have at least 2 tips of different lengths. At first this didn't work in my lamp. After examining and purchasing a lightbulb at a local Lowe's store, I found that the grommets come in a variety of lengths. My mount required a longer tip. This bulb and the one sold by Lowe had no electrical contact. I solved the problem by soldering a large solder pad onto the tip to contact it. Now everything is in order. This bulb was $10…
