Halogen to LED work lights

Two questions:

I have two sets of Craftsman halogen work lights.

One is a twin unit and uses 500 watt or less halogen bulbs. I know I can insert a LED and it will work. I plan on keeping one side as Halogen (extra bright along with heat if needed) the other side with an equivalent 300 watt T-3 LED. But is there a 500 watt equivalent LED I can use? What is the brightest LED T-3 replacement?




The second work light is a single halogen Craftsman model 9.83991 and uses a two bulb configuration to allow 150/300/500 watt brightness as you push the switch. Can I use a LED in this unit? Will I need to replace both bulbs and will I get the three levels (or at least two levels) of brightness? Can I mix LED and halogen?

I don't know for sure but would say very doubtful.
The problem is trying to jam a lot of wattage in a small area. LED's must cool off or they'll fry.

You could probably get a high power LED assembly to go into that light but not in the tube socket.

Then I guess I stick with the 300 watt equivalent LED. According to several YOU TUBE videos they work out very well.

Any T3 led with the same base, length and same or less watts equivalent as the old halogen and operates from 120 vac should be OK. The driver in the base of an LED lamp operates from 120 vac gets hotter than the globe. Don't know if this is hotter than the base of the halogen. I think it is impossible to get 500 watt brightness with two lamps when the other options are 150/300 watts of brightness. Sounds like a marketing thing.

I've never used on of these, but they look like it would match what you're looking for. You'd have to ensure that it fits in your fixture.

Philips makes a cob LED specific for these work lights and for use with any halogen 18mm. So I went and bought two and decided to make the twin unit all LED since the single unit with two bulbs did not seem to work with the any combination of two LED's or one LED and halogen. So the single unit with duel bulbs will be my halogen, when I need heat and the twin unit just for light. The brightness of the LED's seems equal to the halogens.

Putting the new LED lamp in parallel with another new lamp or old halogen in your fixture must change the impedance of the LED driver causing it to become inoperable. Does the LED lamp packaging contain any restrictions? Will the new LED lamp operate by itself in the fixture? Did the old halogen operate with a new LED installed?

The duel work lamp is a Craftsman model 9.83991 and can be at three levels. Found this in the manual and may explain a lot to those of you who better understand this than I.

Your lamp has a four position push button switch for operating at three
light levels:
1. Press Once
Low- 150watt
(resistor cuts power on 300 watt bulb)
2. Press Twice
Medium- 300watt
3. Press Third Time
High- 500watt
4. Press Fourth Time
Turns the lamp off

So I decided to keep the duel light with halogen (but both bulbs at 200 watt, since they come in two packs) and the twin unit with LED's. Both lights work very well.
