GutReise 10pcs E10 Screw 4.5V Yellow Flood Light Led Bulb Flood Light Lamps +10pcs E10 Base (4.5V, Yellow)

I ordered these, ignoring the feedback, thinking I may have better luck. No chance, they are a complete waste of time and money. Somehow, I inadvertently placed two orders of these and tested 20 bulbs. ZERO functioned.Should be a simple thing, an LED with resistor to limit the current to ~20 mA, depending on the desired voltage the replacement light was called for. In my case 6V. It's highly possible the polarity is wrong for the LEDs, but additionally the LED isn't attached to the steel base sufficiently to prevent it from twisting apart from the base. This, of course, separates the resistor's connection to the positive contact in the bottom of the base. Poor design, potentially incorrect construction.

These are pretty anemic lights. They throw very little light compared to incandescent bulbs of the same size and voltage rating, and because of the design of the lens, they throw it mostly to the sides. They seem to be designed to work with the reflector in a flashlight, but they're really too dim to be worth much as flashlight bulbs. There's nothing inherently defective about them - they might be fine for some kind of decorative project, but don't expect much else. On the plus side, they do come with screw-in bases and the bases seem well constructed.

These are a nice bulb but what I discovered in my Railroad lantern is that the lantern is actually wired backwards for these bulbs, basically the + plus is on the screw side not the tip on the bottom as you might think so they will not work in some lanterns. I bought a 6v lantern battery adapter and basically installed the batteries (4 D cells) in the adapter backwards (adapter needs to me slightly modified, no big deal if you are handy with a dremel tool) and then they work fine. Other types of lanterns may be wired differently I'm not sure because I've only used them on railroad lanterns, but the adapter is well worth the money and will save you a lot of money on buying 6v lantern batteries.

Great little bulbs. I like that they come with separate sockets, which you can solder on or mount without worrying about damaging the bulb. The holes in the sockets readily take an 18 gauge wire. No troubles soldering. Caution: it is easy to damage the bulb when twisting it in - they bottom out at the end of the thread but with metal still showing. If you keep twisting, the plastic will turn but the base is in, so you'll rip it apart. It takes very little force to do this. Otherwise, great. (I bought 6V white.)

I like the quality of these bulbs and was pleased to find that I could get them in several colors as well as in spot or flood.They are not quite as bright as I would have liked however they will serve the purposeAlso wish the blubs were available in multicolor sets. If you are looking for a few red, a few blue and a few white, you would have to buy 3 separate packages each with 10 of each color.

Bulbs arrived quickly. Installed one bulb which worked perfectly. Light is bright and bulb fit into socket without any play or looseness. Have not used connectors that came with bulbs but will think of a way to utilize them as I don't have that many lights to replace. Definitely will buy again if need arises.

These lights worked great to replace bulbs in the Christmas tree that belonged to my grandmother.I like the color and the lights do not get hot. I like that too.

These LEDs are bright white and exactly what I needed to replace the football lights in my cart. The only con I can think of is that care must be taken not to over tighten or the dome may separate from the base.
