Discount R7s J78 Energy Saving Warm White 24 SMD LED Halogen Light Lamp Bulb

Customer Ratings:

I have four of these in my bathroom to substitute the four 150 watt bulbs originally in the fixture. I was delighted to find these halogen substitutes. Before the room would get hot over time due to the heat and used 600 watts(!) to light it, now cool, low wattage light. While not quite as bright as the halogens, these provided nice whiter light at very adequate brightness, and I'm very pleased.

I'm using this bulb to replace a 100w T6 halogen in an old 3-way desk lamp. At first I had some trouble with installation, the bulb is a few millimeters longer than a standard double ended t6. The back of the unit is covered by an aluminium heatsink shroud. One of the downsides to this design is that it produces a much narrower cone of light than a halogen would.

The lumens produced is roughly equal to a 50w halogen bulb. This amount of light is perfect for my needs in my size desk lamp, I've always felt the original 100w halogen bulb was overkill on the highest setting.

The color consistency of the LED bulb is very poor, casting a nasty greenish yellow light that is nowhere near warm white. I have tried to correct this with various blue gels but have been unsuccessful so far.

The unit is non-dimmable, it will strobe and buzz at any level less than full power.

This is my seventh LED bulb; I've purchased different units at all price ranges. The more expensive bulbs have the best color consistency, dimmability and heat management. Cheaper bulbs were mislabeled as flood instead of spot, most would not work in any dimmers at all, and the color quality of light produced is worse than many florescent lamps. However if all you want is to save money and energy, then this and other cheap LEDs are a fine solution. Although I would rather pay double for dimmability and color quality and will not buy another cheap LED bulb in the future.
